They only contribute typed fragments to semantic +slots, and the adapter builder owns the algebra for those slots. + +### Patch laws + +Patches should satisfy these laws unless a comment explains why not: + +- Determinism: same input and context produce the same output and trace. +- Locality: a patch only touches its declared phase or slot. +- Idempotence: applying the same patch twice should usually be equivalent to + applying it once. +- Monotonic trace: if a patch changes output, it emits exactly one trace entry. +- Validation boundary: final target validation happens after all patches for a + target have run. +- No hidden I/O: request, prompt, schema, and target patches are pure. + +Idempotence is especially useful for model quirks. A patch like +`target.openai-chat.include-usage` should set `include_usage: true`, not append a +second usage directive.

Start with AI SDK pure lowering tests for OpenAI-compatible and OpenAI + Responses. Convert their inputs into `LLMRequest` fixtures and snapshots into + provider target snapshots. +2. Use AI SDK stream/model tests to build provider chunk fixtures for OpenAI + Chat and Responses. +3. Use Pi tests for regression cases AI SDK does not cover, especially + cross-provider handoff, tool ID normalization, media in tool results, + reasoning signatures, and cache behavior. +4. Keep live/e2e tests optional behind env vars. The package's required test + suite should be deterministic and fixture-based. + +## Prior art + +### AI SDK + +AI SDK's provider architecture is mature and worth studying. It is not "bad" +code, but it is shaped by a broad public API, browser/server use cases, UI +helpers, provider package compatibility, telemetry, callbacks, retries, tools, +and legacy evolution. That makes the code heavier than what this package should +start with. + +Useful ideas to borrow: + +- A narrow provider interface. `LanguageModelV3` has `doGenerate` and + `doStream`, plus provider/model identity and supported URL metadata. +- A standardized provider prompt separate from user-facing prompt inputs. +- A standardized stream-part union with text, reasoning, tool input, tool calls, + files, sources, metadata, finish, raw, and error parts. +- Provider-specific request lowering isolated in provider packages. +- Tool preparation separated from tool execution. +- Tool execution as a stream transformation that can delay finish until tool + results are emitted. +- Test-server and fixture-heavy provider tests. +- Explicit `providerOptions` and `providerMetadata` escape hatches. +- Stream parts for partial tool input, not just final tool calls. + +Things to avoid copying directly: + +- A very large `streamText` orchestration surface that mixes prompt + standardization, retries, telemetry, callbacks, tool loops, result promises, + UI streams, and output parsing. +- User-facing UI message concerns in the core model package. +- Wide provider option bags as the main extensibility mechanism. +- Heavy overload/type gymnastics for public SDK ergonomics before the internal + algebra is stable. +- Direct `ReadableStream`-first internals when Effect `Stream` can keep errors, + interruption, scope, and services explicit. + +The best AI SDK lesson is: keep the provider contract small, but expect the +orchestration layer to grow if tool execution, UI streams, callbacks, retries, +and structured output all live in one function. This package should split those +concerns from the beginning. + +### Effect Smol unstable AI + +Effect Smol's `effect/unstable/ai` modules are closer to the desired shape. +Relevant files live under `../effect-smol/packages/effect/src/unstable/ai`. + +Useful ideas to borrow: + +- `Prompt` and `Response` are Schema-owned domain models with encoded and + decoded representations. +- `Tool` and `Toolkit` use Schema for parameters, success, and failure outputs, + then decode inputs and encode outputs at execution boundaries. +- `LanguageModel.make` separates provider implementations from higher-level + generation and stream orchestration. +- `Response.StreamPart(toolkit)` builds a stream-part schema that is specialized + by the active toolkit. +- `disableToolCallResolution` makes tool execution optional instead of forcing + one runtime policy. +- `CodecTransformer` is exactly the right abstraction for provider-specific + structured-output schema rewriting. +- `OpenAiStructuredOutput` and `AnthropicStructuredOutput` show how to transform + Effect Schema ASTs while preserving decoded types. +- `ResponseIdTracker` is a small focused service for incremental prompts and + previous response IDs. +- Tests use `withLanguageModel(...)` to inject fake model services without + mocking the whole world. + +Things to avoid copying directly: + +- The high-level `LanguageModel` and `Chat` APIs are broad application APIs, not + just a provider adapter core. +- Some type-level machinery is optimized for public Effect ergonomics and may be + too heavy for a first prototype. +- The unstable AI modules do not solve all provider-native lowering and patch + needs; they provide a strong domain/runtime shape, not a full replacement for + provider adapters. + +Most important Effect Smol inspiration: schemas should be executable contracts, +not documentation. Prompt parts, response parts, tool params/results, structured +output codecs, and provider chunks should all be decoded or encoded at explicit +boundaries. + +## Ideal testing strategy + +The test suite should be a pyramid with deterministic tests at the base and a +small number of live provider tests at the top. + +```text +many: schema, lowering, patch, parser, event, property tests +some: adapter contract tests with recorded chunks/responses +few: live provider smoke tests behind env vars +rare: cross-provider e2e handoff tests +``` + +### Unit and fixture tests + +Most tests should be ordinary unit tests over pure data. + +These are the core tests: + +- Decode valid and invalid `LLMRequest` values with Effect Schema. +- Lower `LLMRequest` fixtures into provider target drafts. +- Validate drafts into provider target ASTs. +- Snapshot final redacted provider request bodies. +- Apply patch plans and snapshot patch traces. +- Decode provider stream chunks from captured fixtures. +- Raise decoded chunks into `LLMEvent` sequences. +- Normalize usage from provider payloads. +- Parse partial tool-call JSON into stable input events. +- Verify tool schema sanitation for providers like Gemini. +- Verify media routing for user input and tool results. + +These tests should not hit the network. They should run fast and be safe in CI. + +### Adapter contract tests + +Every adapter should share the same contract test suite where possible. + +Contract cases: + +- text-only request lowers to valid target and emits text events +- tool-call request lowers tools and emits tool input/call events +- reasoning request emits reasoning events when chunks contain reasoning +- usage payload normalizes into `Usage` +- provider error payload normalizes into `ProviderRequestError` or + `ProviderErrorEvent` +- malformed chunks produce `ProviderChunkError` +- terminal provider event ends the stream even if the body remains open +- aborting the stream interrupts parsing and transport cleanly + +The contract suite can be parameterized by adapter: + +```ts +runAdapterContractTests({ + name: "openai-chat", + adapter: OpenAIChatAdapter, + fixtures: OpenAIChatFixtures, +}) +``` + +Adapter-specific tests still exist for native weirdness, but the shared contract +prevents every provider from inventing its own semantics. + +### Property tests + +Property tests help for algebra and parsing invariants. They are not a +replacement for provider fixtures because provider APIs have many arbitrary +rules. Use them where the property is ours. + +Good property-test targets: + +- Patch planning is deterministic regardless of input patch array order when + `phase`, `order`, and `id` are fixed. +- Empty patch plan is identity. +- Patch-plan composition is associative for pure patches. +- Idempotent patches remain idempotent. +- Patch traces are stable and contain exactly the selected patches. +- Target builder `concat` is associative for slots that claim monoidal behavior. +- `append-keyed` rejects duplicate keys or keeps a deterministic winner, + depending on the declared law. +- Header merge is case-insensitive. +- JSON schema sanitation is idempotent. +- Tool-call ID normalization always produces provider-legal IDs and avoids + collisions for a generated corpus. +- SSE parser handles arbitrary chunk boundaries. +- Text/event streams split across arbitrary byte boundaries decode to the same + event sequence as unsplit streams. +- Partial JSON parser never throws for arbitrary prefixes; it returns either a + partial object, empty object, or typed parse error. + +Libraries to consider: + +- `fast-check` is the pragmatic TypeScript choice. +- Effect's test/schema tooling can help generate schema-shaped values if that + becomes ergonomic enough locally. + +Property tests to avoid: + +- Do not generate arbitrary provider request bodies and assert provider behavior. + The provider behavior is not algebraic and will produce noisy tests. +- Do not snapshot property-generated values. Assert laws and invariants instead. +- Do not make property tests depend on network calls. + +### Golden fixture tests + +Golden tests should cover provider-native inputs and outputs that are easy to +break accidentally. + +Fixture layout: + +```text +test/fixture/ + openai-chat/ + text.request.json + text.stream.sse + text.events.json + tool-call.request.json + tool-call.stream.sse + tool-call.events.json + openai-responses/ + anthropic/ + gemini/ +``` + +Golden tests should store redacted provider requests and captured stream bodies, +not secrets or full live transcripts. When a provider changes, update fixtures +deliberately and keep a note about the upstream behavior change. + +### Live integration tests + +Live provider tests are useful but should be few, explicit, and optional. + +Use live tests for: + +- proving credentials/auth/headers work +- detecting provider API drift not represented in fixtures +- smoke-testing one text-only request per major protocol +- smoke-testing one tool-call request for OpenAI Chat, OpenAI Responses, and + Anthropic +- validating cache/reasoning behavior that cannot be trusted from static + fixtures + +Live test rules: + +- Skip unless the required env vars are present. +- Use cheap models and tiny prompts. +- Assert structural behavior, not exact wording. +- Use generous timeouts but keep the number of live tests small. +- Never run live tests in default PR CI unless explicitly configured. +- Record sanitized request/response fixtures from live tests when adding a new + regression. + +Example live test categories: + +- `OPENAI_API_KEY`: OpenAI Chat text and tool call +- `OPENAI_RESPONSES_API_KEY`: Responses text, reasoning metadata if available +- `ANTHROPIC_API_KEY`: Anthropic text, tool call, cache metadata smoke +- `GOOGLE_API_KEY`: Gemini text and schema/tool smoke +- `OPENROUTER_API_KEY`: OpenAI-compatible proxy smoke + +### Cross-provider tests + +Cross-provider handoff is important for coding agents because histories can move +between models. These tests should mostly be deterministic fixtures. + +Important cases: + +- OpenAI Responses tool-call IDs replayed into OpenAI Chat-compatible providers. +- Copilot/OpenAI tool-call IDs replayed into Anthropic. +- Gemini thought signatures preserved when returning to Gemini. +- Tool results with images replayed into providers that do and do not support + media in tool results. +- Reasoning content replayed into providers that require native reasoning fields. +- Histories with interrupted/pending tool calls converted into valid provider + histories. + +Only a very small subset of cross-provider tests should be live. Most should use +captured histories and assert target request validity. + +### Mutation and differential tests + +During migration from AI SDK, differential tests are valuable. + +For providers still backed by AI SDK, compare: + +- our lowered target request vs AI SDK lowered request where observable +- our event stream vs AI SDK full-stream event sequence for captured chunks +- our usage normalization vs AI SDK usage normalization + +This does not mean copying AI SDK behavior forever. It gives us a migration +guardrail while replacing the abstraction. + +Mutation-style checks can be simple: + +- Remove a required patch from the selected patch set and assert a fixture fails + target validation or violates an expected target snapshot. +- Corrupt a stream chunk and assert a typed chunk error. +- Remove a tool result from history and assert the prompt patch repairs or + rejects the history according to protocol rules. + +### What to optimize for + +Prioritize tests that catch these failures: + +- Provider 400s caused by subtly invalid message ordering. +- Tool call arguments streaming incorrectly or failing to parse partial JSON. +- Tool call IDs invalid for the next provider. +- Reasoning/thinking fields omitted or sent to the wrong native path. +- Cache-control metadata attached at the wrong level. +- Media routed into tool results for providers that reject it. +- Token usage double-counting cached or reasoning tokens. +- Streams hanging after a provider terminal event. +- Abort not cancelling transport or parser work. +- Config/native extension patches mutating undeclared target paths. + +The ideal default suite is many deterministic tests plus property tests for our +own algebra. Live requests are a smoke/regression layer, not the main source of +confidence. + +## MVP plan + +### Phase 1: Package skeleton and schemas + +Goal: define the standalone API without touching opencode runtime behavior. + +1. Add `packages/llm` or `packages/opencode/src/llm-core` with no imports from + opencode session modules. +2. Add `schema.ts` with `ModelRef`, `LLMRequest`, `Message`, `ContentPart`, + `ToolDefinition`, `LLMEvent`, `Usage`, and errors. +3. Add `target.ts` with `TargetBuilder`, `TargetFragment`, and `TargetSlot`. +4. Add `patch.ts` with `Patch`, `PatchContext`, ordering, apply helpers, and + traces. +5. Add schema decoding tests for valid and invalid requests/events. + +Acceptance criteria: + +- The package compiles independently. +- No session-specific types are imported. +- A consumer can construct and validate an `LLMRequest`. + +### Phase 2: OpenAI Chat adapter without tool execution + +Goal: prove lowering, target fragments, transport, SSE parsing, and event +raising for the simplest useful protocol. + +1. Add `provider/openai-chat.ts` with `OpenAIChatDraft`, `OpenAIChatRequest`, and + chunk schemas. +2. Lower system parts, messages, generation options, and tools into a draft. +3. Validate the draft into a provider target with Effect Schema. +4. Implement SSE parsing from `Response` to decoded chunks. +5. Raise chunks into text, tool-input, tool-call, usage, and finish events. +6. Test entirely from captured fixture chunks and target snapshots. + +Acceptance criteria: + +- A text-only fixture produces the expected `LLMEvent` sequence. +- A tool-call fixture assembles partial JSON input into one `tool-call` event. +- Target snapshots show provider-native OpenAI Chat payloads. + +### Phase 3: Patch engine with real quirks + +Goal: validate composability against known exceptions. + +1. Implement prompt patches for unsupported media and empty content. +2. Implement schema patch for Gemini JSON Schema sanitation as a protocol-neutral + schema transformer. +3. Implement target patches for OpenAI-compatible usage, Alibaba thinking, and + GPT-5 defaults. +4. Attach patch traces to prepared requests and provider request errors. +5. Test patch selection against synthetic `ModelRef` fixtures. + +Acceptance criteria: + +- Patches can be selected by provider, protocol, model ID, capabilities, and + request flags. +- Patch traces are deterministic and snapshot-tested. +- Conflicting fragments can be detected by the target builder. + +### Phase 4: Optional tool runtime + +Goal: prove the package can provide an AI SDK-like loop without forcing every +consumer to use it. + +1. Add `tool-runtime.ts` with max step handling. +2. Execute `ExecutableTool`s when tool calls are emitted. +3. Append tool result messages and continue the stream. +4. Surface tool execution failures as `tool-error` events. +5. Keep permission, UI, and persistence decisions outside the package. + +Acceptance criteria: + +- In-memory tool fixtures can complete a two-step tool-call conversation. +- Consumers can still choose to manually handle tool calls without the runtime. + +### Phase 5: Opencode integration adapter + +Goal: use the package from opencode without migrating every provider. + +1. Add a small translator from opencode's current session state into + `LLMRequest` outside the package. +2. Add a translator from `LLMEvent` into current session processor events outside + the package if needed. +3. Gate native OpenAI Chat behind an experimental config flag. +4. Keep AI SDK as the default path during evaluation. +5. Compare request payloads and event sequences for simple prompts and tool + calls. + +Acceptance criteria: + +- The package remains session-agnostic. +- Native OpenAI Chat can run one real request behind a flag. +- Existing AI SDK behavior remains the default fallback. + +### Phase 6: Add more protocols + +Goal: prove the abstractions hold for less uniform providers. + +Order: + +1. OpenAI Responses for GPT-5 and OAuth-like flows. +2. Anthropic Messages for thinking, cache control, and strict tool rules. +3. Gemini for schema sanitation and thinking config. +4. Bedrock once Anthropic and Gemini target ASTs are stable. + +Acceptance criteria: + +- Each protocol has target schemas, chunk schemas, fixture tests, and patch + tests. +- Provider-specific weirdness lives in adapter-local lowerers or named patches. +- No consumer code branches on provider internals to build request payloads. + +## MVP defaults + +Use these defaults unless implementation proves they are wrong. + +- Land the first version under `packages/opencode/src/llm-core` only if creating a + workspace package slows the prototype. Keep imports package-clean either way. +- Treat patch IDs as internal until config, plugin, or public docs reference them. + Once referenced externally, require stable IDs and deprecation notes. +- Keep `ModelRef.native` and `LLMRequest.native` as + `Schema.Record(Schema.String, Schema.Unknown)` for the MVP, but decode every + consumed native value through adapter-owned schemas before use. +- Prefer native structured output when an adapter has strong fixture coverage for + that model/protocol. Prefer forced tool calls for providers where native JSON + schema is known to be brittle. +- Leave retries outside the package for the MVP. The transport abstraction should + make retries injectable later without changing adapters. +- Pass resolved auth headers in `ModelRef.headers` or `TransportContext`. + Adapters may add protocol headers like beta flags, but should not discover + credentials. +- Expose raw provider chunks only through debug hooks and fixture helpers, not as + required consumer events. Stable consumers should depend on `LLMEvent` plus + patch traces. +- Make `stream` the only required adapter runtime path. Implement `generate` by + accumulating `LLMEvent`s so streaming and non-streaming behavior cannot drift. +- Keep tool execution opt-in. The default adapter stream ends at tool-call events + and finish events; `ToolRuntime` is a helper layered above it. + +## Migration risks + +The main migration risk is not type modeling. It is behavioral parity around +provider-specific invalid histories and streaming edge cases. + +High-risk areas: + +- Cross-provider replay of historical tool calls and tool results. +- Partial tool input JSON and providers that emit missing or malformed args. +- Reasoning/thinking content that must be preserved for one provider and removed + or converted for another. +- Cache-control metadata attached at message vs content-block vs provider-option + level. +- Streams that emit finish markers before the HTTP body closes. +- Usage accounting with cached input, output, and reasoning token fields. +- Provider-specific schema sanitation, especially Gemini/OpenAPI-like schemas. + +Mitigation: + +- Start with OpenAI Chat because the request shape is simple and opencode already + relies heavily on OpenAI-compatible providers. +- Add OpenAI Responses second because it exercises IDs, reasoning, item-style + input, and modern GPT-5 behavior. +- Convert current `src/provider/transform.ts` branches into named patches one at + a time. Each extracted patch needs a fixture before removing the old branch. +- Run differential tests against AI SDK fixtures during migration, but do not make + AI SDK parity a permanent product requirement. +- Keep the current AI SDK path as the default until a native adapter has fixture + parity for text, tools, reasoning, abort, usage, and provider errors. + +## First implementation slice + +The smallest useful implementation should be docs-to-code mechanical. + +1. Create `llm-core/schema.ts` with only schemas and errors. +2. Create `llm-core/patch.ts` with pure patch planning and trace tests. +3.

The Schema classes in `src/schema.ts` are the canonical runtime data model. Convenience functions in `src/llm.ts` are thin constructors that return those same Schema class instances; they should improve callsites without creating a second model. + +### Request Flow + +The intended callsite is: + +```ts +const request = LLM.request({ + model: OpenAIChat.model({ id: "gpt-4o-mini", apiKey }), + system: "You are concise.", + prompt: "Say hello.", +}) + +const response = yield* client({ adapters: [OpenAIChat.adapter] }).generate(request) +``` + +`LLM.request(...)` builds an `LLMRequest`. `client(...)` selects an adapter by `request.model.protocol`, applies patches, prepares a typed provider target, converts that target into a `TransportRequest`, sends it through `Transport.Service`, parses the provider stream, raises common `LLMEvent`s, and finally returns an `LLMResponse`. + +### Adapters + +Adapters are provider/protocol boundaries.

If a behavior is not universal enough for common IR, keep it as a named patch with a trace entry. Good examples: + +- OpenAI Chat streaming usage: `target.openai-chat.include-usage` adds `stream_options.include_usage`. +- Anthropic prompt caching: map common cache hints onto selected content/message blocks. +- Mistral/OpenAI-compatible prompt cleanup: normalize empty text content or tool-call IDs only for affected models. +- Reasoning models: map common reasoning intent to provider-specific effort, summary, or encrypted-content fields. + +Do not grow common request schemas just to fit one provider.

Prefer Effect `Schema` for API and domain data shapes. Use branded schemas for IDs and `Schema.TaggedErrorClass` for typed domain errors when modeling new error surfaces. - Keep HTTP handlers thin: decode input, read request context, call services, and map transport errors. Put business rules in services. - In Effect service code, prefer Effect-aware platform abstractions and dependencies over ad hoc promises where the surrounding code already does so. +- Service public methods should not leak implementation dependencies. Yield required services once while constructing the layer, close over them in the returned service implementation, and keep method return types focused on the service API rather than requiring callers to provide transitive dependencies. - Keep layer composition explicit. Avoid broad hidden provisioning that makes missing dependencies hard to see. - In tests, prefer the repo's existing Effect test helpers and live tests for filesystem, git, child process, locks, or timing behavior. - Do not introduce `any`, non-null assertions, unchecked casts, or older Effect APIs just to satisfy types. diff --git a/bun.lock b/bun.lock index 2c3efd1c4076..41884b717c09 100644 --- a/bun.lock +++ b/bun.lock @@ -359,6 +359,7 @@ "effect": "catalog:", }, "devDependencies": { + "@effect/platform-node": "catalog:", "@tsconfig/bun": "catalog:", "@types/bun": "catalog:", "@typescript/native-preview": "catalog:", diff --git a/packages/llm/package.json b/packages/llm/package.json index baeff77e2117..cc916ea7c4a6 100644 --- a/packages/llm/package.json +++ b/packages/llm/package.json @@ -14,6 +14,7 @@ "./*": "./src/*.ts" }, "devDependencies": { + "@effect/platform-node": "catalog:", "@tsconfig/bun": "catalog:", "@types/bun": "catalog:", "@typescript/native-preview": "catalog:" diff --git a/packages/llm/src/adapter.ts b/packages/llm/src/adapter.ts index 0dd1d3c8eef7..3459d71c1367 100644 --- a/packages/llm/src/adapter.ts +++ b/packages/llm/src/adapter.ts @@ -3,25 +3,9 @@ import { HttpClientRequest, type HttpClientResponse } from "effect/unstable/http import { RequestExecutor } from "./executor" import type { AnyPatch, Patch, PatchInput, PatchRegistry } from "./patch" import { context, emptyRegistry, plan, registry as makePatchRegistry, target as targetPatch } from "./patch" -import type { -

Structurally match recorded requests by canonical JSON so non-deterministic field ordering doesn't break replay. - Pluggable header allow-list and body redaction hook on the record/replay layer, so adapters with non-default auth (Anthropic, Bedrock) can plug in without touching this file. - Move the cassette-name dedupe set inside recordedTests() so two describe files using different prefixes can run in parallel. - Replace inline SSE template literals and per-file HTTP layers with shared test/lib helpers (sseEvents, fixedResponse, dynamicResponse, truncatedStream). - Tighten recorded-test assertions to exact text and usage so adapter parser regressions surface immediately instead of passing fuzzy length>0 checks. - Add cancellation and mid-stream transport-error tests for the OpenAI Chat adapter. - Add cross-phase patch tests that verify each phase sees an updated PatchContext and that same-order patches sort deterministically by id. --- packages/llm/test/adapter.test.ts | 124 ++++++++--- packages/llm/test/lib/http.ts | 58 ++++++ packages/llm/test/lib/sse.ts | 20 ++ .../provider/openai-chat.recorded.test.ts | 33 ++- .../llm/test/provider/openai-chat.test.ts | 136 ++++++++----- packages/llm/test/record-replay.ts | 192 ++++++++++++++---- packages/llm/test/recorded-test.ts | 20 +- 7 files changed, 454 insertions(+), 129 deletions(-) create mode 100644 packages/llm/test/lib/http.ts create mode 100644 packages/llm/test/lib/sse.ts diff --git a/packages/llm/test/adapter.test.ts b/packages/llm/test/adapter.test.ts index e9017dc416b1..539086b6e837 100644 --- a/packages/llm/test/adapter.test.ts +++ b/packages/llm/test/adapter.test.ts @@ -1,11 +1,22 @@ import { describe, expect } from "bun:test" -import { Effect, Layer, Schema, Stream } from "effect" -import { HttpClient, HttpClientRequest, HttpClientResponse } from "effect/unstable/http" +import { Effect, Schema, Stream } from "effect" +import { HttpClientRequest } from "effect/unstable/http" import { LLM } from "../src" import { Adapter, client } from "../src/adapter" -import { RequestExecutor } from "../src/executor" import { Patch } from "../src/patch" +import type { LLMRequest } from "../src/schema" import { testEffect } from "./lib/effect" +import { dynamicResponse } from "./lib/http" + +const mapText = (fn: (text: string) => string) => (request: LLMRequest): LLMRequest => ({ + ...request, + messages: request.messages.map((message) => ({ + ...message, + content: message.content.map((part) => + part.type === "text" ? { ...part, text: fn(part.text) } : part, + ), + })), +}) const Json = Schema.fromJsonString(Schema.Unknown) const encodeJson = Schema.encodeSync(Json) @@ -42,8 +53,7 @@ const fake = Adapter.define({ .filter((part) => part.type === "text") .map((part) => part.text), ...request.tools.map((tool) => `tool:${tool.name}:${tool.description}`), -

11:04:36 -0400 Subject: [PATCH 016/196] refactor(llm): yieldable parser errors and linear runFold - shared sse helper now expects Effectful decodeChunk and process callbacks, so adapter parsers can be Effect.gen and yield typed ProviderChunkError instead of throwing across the sync mapAccum boundary. - parseJson returns Effect via Effect.try, matching the package style guide on yieldable errors. - OpenAI Chat finalizes accumulated tool inputs eagerly when finish_reason arrives, surfacing JSON parse failures at the boundary instead of at halt. onHalt stays sync and just emits from state. - generate's runFold reducer now mutates the accumulator instead of reallocating the events array on every chunk, dropping O(n^2) growth on long streams. --- packages/llm/src/adapter.ts | 9 +-

The sanitizer was previously a divergent copy in OpenCode; this lands it in the package as a tool-schema patch with deterministic tests and selects it for Gemini-protocol or Gemini-named models. Also tightens the Gemini test suite: covers tool-choice none, drops the tool-input-delta assertion that Gemini does not actually emit, and confirms total usage stays undefined when only thoughtsTokenCount arrives. --- packages/llm/src/provider/patch.ts | 63 ++++++++++++++- .../llm/test/provider/gemini.recorded.test.ts | 1 -

Findings from a parallel review (code reuse + quality + perf): src/tool.ts - Tool now carries memoized decode/encode codecs and a precomputed ToolDefinition, derived once at tool() construction time. The runtime no longer rebuilds Schema closures or JSON Schema docs per call/per run. - Constrains parameters/success to Schema.Codec so the codecs have no service requirements. Drops the 'as unknown as' casts the runtime needed previously. - Fixes a latent bug: schemas with $ref now correctly emit $defs on ToolDefinition.inputSchema (toJsonSchemaDocument's definitions were silently dropped before). src/tool-runtime.ts - Uses LLMRequest constructor instead of 'as LLMRequest' casts. - Default tool dispatch concurrency is 10 (was 'unbounded'); exposed via RunOptions.concurrency. Unbounded is still available for handlers that do not share a saturable resource. - Drops dead 'usage' state, the single-use Dispatched interface, and the DEFAULT_MAX_STEPS constant per the inline-when-used style rule. - accumulate() now factors text-delta and reasoning-delta into one helper. test/lib/openai-chunks.ts (new) - Shared deltaChunk / usageChunk / toolCallChunk / finishChunk helpers. test/lib/http.ts - scriptedResponses moved here from tool-runtime.test.ts so future multi-step adapter tests can reuse it. Also picks up parallel work that swapped HandlerInput to a 'respond' callback for cleaner Response construction. test/tool-runtime.test.ts - Uses LLMEvent.guards for typed event filtering instead of cast-and-check. - Concurrent test now uses sseEvents + deltaChunk instead of a hand-rolled body string. Includes parallel callsite updates in test/adapter.test.ts and test/provider/openai-compatible-chat.test.ts that adopt the 'respond' API in lib/http.ts. --- packages/llm/src/tool-runtime.ts | 136 +++++------- packages/llm/src/tool.ts | 65 +++++- packages/llm/test/adapter.test.ts | 4 +- packages/llm/test/lib/http.ts | 38 +++- packages/llm/test/lib/openai-chunks.ts | 27 +++ .../provider/openai-compatible-chat.test.ts | 2 +- packages/llm/test/tool-runtime.test.ts | 207 ++++++------------ 7 files changed, 233 insertions(+), 246 deletions(-) create mode 100644 packages/llm/test/lib/openai-chunks.ts diff --git a/packages/llm/src/tool-runtime.ts b/packages/llm/src/tool-runtime.ts index 69b8211f684a..e3f36bd5687f 100644 --- a/packages/llm/src/tool-runtime.ts +++ b/packages/llm/src/tool-runtime.ts @@ -1,19 +1,19 @@ -import { Effect, Schema, Stream } from "effect" +import { Effect, Stream } from "effect" +import type { Concurrency } from "effect/Types" import type { LLMClient } from "./adapter" import type { RequestExecutor } from "./executor" import * as LLM from "./llm" -import type { - ContentPart, - FinishReason, - LLMError, - LLMEvent, +import { + type ContentPart, + type FinishReason, + type LLMError, + type LLMEvent, LLMRequest, - ToolCallPart, - ToolResultValue, - Usage, + type ToolCallPart, + type ToolResultValue, } from "./schema" import { ToolFailure } from "./schema" -import { type Tool, type Tools, toDefinitions } from "./tool" +import { type AnyTool, type Tools, toDefinitions } from "./tool" export interface RuntimeState { readonly step: number @@ -29,6 +29,13 @@ export interface RunOptions { * simply stops and the last `request-finish` event is the terminal signal. */ readonly maxSteps?: number + /** + * How many tool handlers to dispatch in parallel within a single step. + * Defaults to 10.

That makes tool-loop and retry recordings unworkable: identical requests collapse to one response, and large recordings are unreadable on review. - Add `sequentialMatcher` for position-based dispatch so identical retries map to recorded responses in order via an internal cursor. - Pretty-print cassette JSON on write and reformat existing fixtures so multi-interaction diffs stay reviewable. - Add deterministic `record-replay.test.ts` covering default vs sequential dispatch and cursor exhaustion. - Add an OpenAI Chat tool-loop recorded test scaffold gated behind `OPENAI_API_KEY` so a single `RECORD=true` run captures every model round of the loop into one cassette file. - Update AGENTS.md to document multi-interaction cassettes and the matcher options, and mark the cassette ergonomics TODO complete. --- packages/llm/AGENTS.md | 24 +++++- .../anthropic-messages/streams-text.json | 24 +++++- .../anthropic-messages/streams-tool-call.json | 24 +++++- .../recordings/gemini/streams-text.json | 23 ++++- .../recordings/gemini/streams-tool-call.json | 23 ++++- .../continues-after-tool-result.json | 23 ++++- .../recordings/openai-chat/streams-text.json | 23 ++++- .../openai-chat/streams-tool-call.json | 23 ++++- .../deepseek-streams-text.json | 23 ++++- .../togetherai-streams-text.json | 22 +++++ .../togetherai-streams-tool-call.json | 22 +++++ .../recordings/record-replay/multi-step.json | 39 +++++++++ .../recordings/record-replay/retry.json | 39 +++++++++ .../openai-chat-tool-loop.recorded.test.ts | 69 +++++++++++++++ .../openai-compatible-chat.recorded.test.ts | 57 +++++++++++++ packages/llm/test/record-replay.test.ts | 63 ++++++++++++++ packages/llm/test/record-replay.ts | 83 ++++++++++++++----- 17 files changed, 571 insertions(+), 33 deletions(-) create mode 100644 packages/llm/test/fixtures/recordings/openai-compatible-chat/togetherai-streams-text.json create mode 100644 packages/llm/test/fixtures/recordings/openai-compatible-chat/togetherai-streams-tool-call.json create mode 100644 packages/llm/test/fixtures/recordings/record-replay/multi-step.json create mode 100644 packages/llm/test/fixtures/recordings/record-replay/retry.json create mode 100644 packages/llm/test/provider/openai-chat-tool-loop.recorded.test.ts create mode 100644 packages/llm/test/record-replay.test.ts diff --git a/packages/llm/AGENTS.md b/packages/llm/AGENTS.md index 3192cda82521..4ac7ff978ef2 100644 --- a/packages/llm/AGENTS.md +++ b/packages/llm/AGENTS.md @@ -137,7 +137,7 @@ Provider-defined tools (e.g. OpenAI built-in `web_search`) should go directly in ### Recording Tests -Recorded tests use one cassette per scenario.

This is the right choice for tool loops because each round's request differs (the message history grows). For scenarios where successive requests are byte-identical and expect different responses (retries, polling), pass `match: sequentialMatcher` in `RecordReplayOptions` — replay then walks the cassette in record order via an internal cursor. `scriptedResponses` (in `test/lib/http.ts`) is the deterministic counterpart for tests that don't need a live provider; it scripts response bodies in order without reading from disk.

provider-executed tool pass-through Add a `providerExecuted: boolean` flag to `tool-call` and `tool-result` events plus the persisted `ToolResultPart`. When set, the tool runtime skips client dispatch (the provider already executed the tool) and folds both events into the assistant message so the next round's history carries the call + result for context. Anthropic: decode `server_tool_use` blocks and the three server tool result block types (`web_search_tool_result`, `code_execution_tool_result`, `web_fetch_tool_result`) into `tool-call` / `tool-result` events with `providerExecuted: true`. Round-trip the same parts back into the provider when the assistant message is replayed in subsequent requests. Result block error payloads (`*_tool_result_error`) surface as `result.type === "error"`. OpenAI Responses: decode hosted tool items emitted via `response.output_item.done` (`web_search_call`, `file_search_call`, `code_interpreter_call`, `computer_use_call`, `image_generation_call`, `mcp_call`, `local_shell_call`) as `tool-call` + `tool-result` pairs with `providerExecuted: true`. Each tool's input fields are pulled out explicitly; the full item is passed through as the result payload so consumers can read outputs / sources / status without re-decoding. Tool runtime: extend the dispatch decision so provider-executed tool-calls bypass the handler lookup, and tool-result events with `providerExecuted: true` are appended to the assistant content for round-trip rather than being treated as a separate tool message. Tests: 7 new deterministic fixtures cover Anthropic decode (success + error result + round-trip + unknown server tool name), OpenAI Responses decode (web_search_call, code_interpreter_call), and tool-runtime skip-dispatch. AGENTS.md updates the runtime section to describe pass-through behavior and notes the transport-agnostic design that keeps a future WebSocket adapter (e.g. OpenAI Codex backend) as a sibling rather than a core rewrite. --- packages/llm/AGENTS.md | 13 +- .../llm/src/provider/anthropic-messages.ts | 121 ++++++++++++- packages/llm/src/provider/openai-responses.ts | 70 ++++++++ packages/llm/src/schema.ts | 3 + packages/llm/src/tool-runtime.ts | 26 ++- .../test/provider/anthropic-messages.test.ts | 168 ++++++++++++++++++ .../test/provider/openai-responses.test.ts | 74 ++++++++ packages/llm/test/tool-runtime.test.ts | 64 ++++++- 8 files changed, 530 insertions(+), 9 deletions(-) diff --git a/packages/llm/AGENTS.md b/packages/llm/AGENTS.md index 4ac7ff978ef2..67c87761cdd2 100644 --- a/packages/llm/AGENTS.md +++ b/packages/llm/AGENTS.md @@ -47,6 +47,8 @@ Adapters should stay boring and typed: - `toHttp` creates the `HttpClientRequest`. - `parse` decodes provider chunks into `LLMEvent`s.

Subject: [PATCH 033/196] feat(llm): add Bedrock Converse adapter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the AWS Bedrock Converse streaming protocol as the 5th first-class adapter in @opencode-ai/llm. Single `bedrock-converse` adapter covers all underlying models (Anthropic, Llama, Mistral, Cohere, Nova, Titan) since Converse is uniform. Wire format: messages with text / reasoning / toolUse / toolResult content blocks, system blocks, inferenceConfig, toolConfig with toolSpec + toolChoice. Image / document / cache-point content types are still TODO. Streaming: AWS event stream binary framing via @smithy/eventstream-codec. Each frame is decoded then dispatched by `:event-type` header into the chunk schema. Bedrock splits the finish across `messageStop` (reason) and `metadata` (usage) — the parser stashes the reason and emits a single consolidated `request-finish` event when metadata arrives, with an `onHalt` fallback for truncated streams. Auth: two paths. Bearer API key (newer) when the consumer sets `model.headers.authorization = 'Bearer '`. SigV4 signing via aws4fetch otherwise — credentials live on `model.native.aws_credentials` and are signed at `toHttp` time so STS-vended tokens are picked up when the consumer rebuilds the model. The adapter rejects requests with neither auth path with a clear InvalidRequestError. Routing: `@ai-sdk/amazon-bedrock` lowers to `bedrock-converse` via the new `AmazonBedrock` provider routing module; the OpenCode `llm-bridge.ts` registers it. Cassette format: response bodies under `application/vnd.amazon.eventstream` and `application/octet-stream` content types are now stored as base64 with `bodyEncoding: 'base64'` on the response snapshot — text round-tripping mangled the CRC32 fields in event-stream frames. Existing cassettes (SSE/JSON) omit the field and decode as text unchanged. Tests: 11 deterministic fixtures (prepare / lower messages / lower tool config / decode text+usage / decode tool calls / decode reasoning / decode throttling exception / auth path validation / SigV4 plumbing) + 2 recorded cassettes against live Bedrock (`us.amazon.nova-micro-v1:0` in us-east-1) for streaming text and streaming tool calls. AGENTS.md: documents the Bedrock auth model, binary cassette format, and updates the protocol coverage / cassette backlog. Deps: @smithy/eventstream-codec, @smithy/util-utf8, aws4fetch (~40KB combined; matches AI SDK's approach). --- bun.lock | 9 + packages/llm/AGENTS.md | 6 +- packages/llm/package.json | 3 + packages/llm/src/index.ts | 2 + packages/llm/src/provider/amazon-bedrock.ts | 5 + packages/llm/src/provider/bedrock-converse.ts | 677 ++++++++++++++++++ .../bedrock-converse/streams-a-tool-call.json | 23 + .../bedrock-converse/streams-text.json | 23 + .../test/provider/bedrock-converse.test.ts | 375 ++++++++++ packages/llm/test/record-replay.ts | 48 +- packages/opencode/src/provider/llm-bridge.ts | 2 + 11 files changed, 1163 insertions(+), 10 deletions(-) create mode 100644 packages/llm/src/provider/amazon-bedrock.ts create mode 100644 packages/llm/src/provider/bedrock-converse.ts create mode 100644 packages/llm/test/fixtures/recordings/bedrock-converse/streams-a-tool-call.json create mode 100644 packages/llm/test/fixtures/recordings/bedrock-converse/streams-text.json create mode 100644 packages/llm/test/provider/bedrock-converse.test.ts diff --git a/bun.lock b/bun.lock index 037d4c86ed46..9b1c8cfa0d95 100644 --- a/bun.lock +++ b/bun.lock @@ -356,6 +356,9 @@ "name": "@opencode-ai/llm", "version": "1.14.25", "dependencies": { + "@smithy/eventstream-codec": "4.2.14", + "@smithy/util-utf8": "4.2.2", + "aws4fetch": "1.0.20", "effect": "catalog:", }, "devDependencies": { @@ -5652,6 +5655,10 @@ "@opencode-ai/desktop-electron/typescript": ["typescript@5.6.3", "", { "bin": { "tsc": "bin/tsc", "tsserver": "bin/tsserver" } }, "sha512-hjcS1mhfuyi4WW8IWtjP7brDrG2cuDZukyrYrSauoXGNgx0S7zceP07adYkJycEr56BOUTNPzbInooiN3fn1qw=="], + "@opencode-ai/llm/@smithy/eventstream-codec": ["@smithy/eventstream-codec@4.2.14", "", { "dependencies": { "@aws-crypto/crc32": "5.2.0", "@smithy/types": "^4.14.1", "@smithy/util-hex-encoding": "^4.2.2", "tslib": "^2.6.2" } }, "sha512-erZq0nOIpzfeZdCyzZjdJb4nVSKLUmSkaQUVkRGQTXs30gyUGeKnrYEg+Xe1W5gE3aReS7IgsvANwVPxSzY6Pw=="], + + "@opencode-ai/llm/@smithy/util-utf8": ["@smithy/util-utf8@4.2.2", "", { "dependencies": { "@smithy/util-buffer-from": "^4.2.2", "tslib": "^2.6.2" } }, "sha512-75MeYpjdWRe8M5E3AW0O4Cx3UadweS+cwdXjwYGBW5h/gxxnbeZ877sLPX/ZJA9GVTlL/qG0dXP29JWFCD1Ayw=="], + "@opencode-ai/ui/@solid-primitives/resize-observer": ["@solid-primitives/resize-observer@2.1.3", "", { "dependencies": { "@solid-primitives/event-listener": "^2.4.3", "@solid-primitives/rootless": "^1.5.2", "@solid-primitives/static-store": "^0.1.2", "@solid-primitives/utils": "^6.3.2" }, "peerDependencies": { "solid-js": "^1.6.12" } }, "sha512-zBLje5E06TgOg93S7rGPldmhDnouNGhvfZVKOp+oG2XU8snA+GoCSSCz1M+jpNAg5Ek2EakU5UVQqL152WmdXQ=="], "@opencode-ai/web/@shikijs/transformers": ["@shikijs/transformers@3.20.0", "", { "dependencies": { "@shikijs/core": "3.20.0", "@shikijs/types": "3.20.0" } }, "sha512-PrHHMRr3Q5W1qB/42kJW6laqFyWdhrPF2hNR9qjOm1xcSiAO3hAHo7HaVyHE6pMyevmy3i51O8kuGGXC78uK3g=="], @@ -6636,6 +6643,8 @@ "@opencode-ai/desktop/@actions/artifact/@actions/http-client": ["@actions/http-client@2.2.3", "", { "dependencies": { "tunnel": "^0.0.6", "undici": "^5.25.4" } }, "sha512-mx8hyJi/hjFvbPokCg4uRd4ZX78t+YyRPtnKWwIl+RzNaVuFpQHfmlGVfsKEJN8LwTCvL+DfVgAM04XaHkm6bA=="], + "@opencode-ai/llm/@smithy/eventstream-codec/@smithy/types": ["@smithy/types@4.14.1", "", { "dependencies": { "tslib": "^2.6.2" } }, "sha512-59b5HtSVrVR/eYNei3BUj3DCPKD/G7EtDDe7OEJE7i7FtQFugYo6MxbotS8mVJkLNVf8gYaAlEBwwtJ9HzhWSg=="], + "@opencode-ai/web/@shikijs/transformers/@shikijs/core": ["@shikijs/core@3.20.0", "", { "dependencies": { "@shikijs/types": "3.20.0", "@shikijs/vscode-textmate": "^10.0.2", "@types/hast": "^3.0.4", "hast-util-to-html": "^9.0.5" } }, "sha512-f2ED7HYV4JEk827mtMDwe/yQ25pRiXZmtHjWF8uzZKuKiEsJR7Ce1nuQ+HhV9FzDcbIo4ObBCD9GPTzNuy9S1g=="], "@opencode-ai/web/@shikijs/transformers/@shikijs/types": ["@shikijs/types@3.20.0", "", { "dependencies": { "@shikijs/vscode-textmate": "^10.0.2", "@types/hast": "^3.0.4" } }, "sha512-lhYAATn10nkZcBQ0BlzSbJA3wcmL5MXUUF8d2Zzon6saZDlToKaiRX60n2+ZaHJCmXEcZRWNzn+k9vplr8Jhsw=="], diff --git a/packages/llm/AGENTS.md b/packages/llm/AGENTS.md index 67c87761cdd2..faf8f896cfaf 100644 --- a/packages/llm/AGENTS.md +++ b/packages/llm/AGENTS.md @@ -157,6 +157,8 @@ recorded.effect("streams text", () => Effect.gen(function* () { Replay is the default. `RECORD=true` records fresh cassettes and requires the listed env vars.

Removes the unsafe `as Record` cast and fixes the dead `native?.region` fallback (the `model()` constructor only writes `aws_region`). - Skip the JSON.parse → JSON.stringify → Schema.fromJsonString triple round-trip in the frame consumer. The eventstream codec already hands us a UTF-8 payload; parse once and feed the wrapped object directly to `Schema.decodeUnknownSync(BedrockChunk)`. - Replace O(n²) buffer concat in `consumeFrames` with a cursor-based state `{ buffer, offset }`. Compaction happens once per network chunk via `appendChunk` instead of per frame; frame slicing is zero-copy via `subarray`. Bounded buffer growth regardless of stream length. - Rename `ParserState.finishReason` → `pendingStopReason` (raw string) and defer the `mapFinishReason` call to the single emit site, plus the `onHalt` fallback. Tightens the helper's signature to `(reason: string)` so the chunk-typed `messageStop.stopReason` flows through without the optional widening. - Restructure `signRequest` to take an object parameter (was four positional args), and replace the manual `forEach`-into-record with `Object.fromEntries(signed.headers.entries())`. - Inline single-use `status` and `useTools` variables. - Widen `fixedResponse` to accept `ConstructorParameters[0]` so binary fixtures (`Uint8Array`, streams) flow without casts.

ProviderShared.joinText(parts) — replaces the per-adapter `text()` helper that joined an array of parts with newlines. Used by OpenAI Chat (system content, user text, assistant text), OpenAI Responses (system content), and Gemini (systemInstruction). The dead copies in Anthropic Messages and Bedrock are gone. ProviderShared.parseToolInput(adapter, name, raw) — replaces the identical `parseJson(adapter, raw || "{}", \`Invalid JSON input for tool call \`)` invocation in finishToolCall across Anthropic, OpenAI Chat, OpenAI Responses, and Bedrock. Uniform error message and the empty-string-to-"{}" fallback handled in one place. ProviderShared.framed(...) — generalizes the existing `sse()` helper so the protocol-specific framing layer is pluggable. The shared shape is bytes → frames → chunk → (state, events) with mapError / mapEffect / mapAccumEffect / catchCause as the spine; framing is the only varying step. ProviderShared.sseFraming — the SSE-specific framing implementation (decodeText + Sse.decode + filter [DONE]). The existing `sse()` helper now delegates to `framed` with this framing, keeping the adapter API surface identical. Bedrock's parseStream — collapses to a single `ProviderShared.framed` call with its own `eventStreamFraming` step. The cursor-based byte buffer + AWS event-stream codec live as inputs to framed; everything else is shared with the SSE adapters. Bedrock now has the same `catchCause → streamError` terminal-error normalization that SSE adapters have (it was missing before this refactor). Net effect across the llm package: -66 lines / +114 lines but the +114 is mostly JSDoc on the new helpers; adapter implementations shrink.

Treats empty input as `{}`.

Three more patterns lifted into ProviderShared so they're written once: ProviderShared.invalidRequest(message) — replaces six identical `const invalid = (message) => new InvalidRequestError({ message })` one-liners across openai-chat, openai-responses, anthropic-messages, gemini, openai-compatible-chat, and bedrock-converse. Each adapter keeps a short `const invalid = ProviderShared.invalidRequest` alias so the 27 callsite `yield* invalid("...")` patterns are unchanged. Bedrock's SigV4 catch path and the openai-compatible-chat baseURL guard both go through the helper now too. ProviderShared.validateWith(decode) — replaces the identical `(draft) => decode(draft).pipe(Effect.mapError((e) => invalid(e.message)))` lambda body in five adapters. Same line count but shorter, names the pattern, and keeps the `decode → mapError → InvalidRequestError` translation in one canonical spot. ProviderShared.jsonPost({ url, body, headers }) — replaces the five-adapter pattern of `HttpClientRequest.post(url).pipe(setHeaders, bodyText)` for JSON-body POSTs. Sets `content-type: application/json` last so caller headers can override everything except the content-type. Bedrock uses it for both the bearer-auth and SigV4- signed paths; SigV4 still signs against `baseHeaders` (which already contained content-type) so the signature matches what the helper ultimately sends. Net change: -73 / +86 (+13 in shared.ts mostly JSDoc; -86 across the six adapters). The `HttpClientRequest` and `InvalidRequestError` imports are dropped from the five SSE adapters and from Bedrock since they're no longer referenced directly. Verified: `bun typecheck` clean, 106 pass / 0 fail / 0 skip (unchanged). --- .../llm/src/provider/anthropic-messages.ts | 20 ++++----- packages/llm/src/provider/bedrock-converse.ts | 23 ++++------- packages/llm/src/provider/gemini.ts | 19 ++++----- packages/llm/src/provider/openai-chat.ts | 19 ++++----- .../src/provider/openai-compatible-chat.ts | 18 ++++---- packages/llm/src/provider/openai-responses.ts | 19 ++++----- packages/llm/src/provider/shared.ts | 41 ++++++++++++++++++- 7 files changed, 86 insertions(+), 73 deletions(-) diff --git a/packages/llm/src/provider/anthropic-messages.ts b/packages/llm/src/provider/anthropic-messages.ts index ea117ff70650..70a4019efbd0 100644 --- a/packages/llm/src/provider/anthropic-messages.ts +++ b/packages/llm/src/provider/anthropic-messages.ts @@ -1,9 +1,8 @@ import { Effect, Schema, Stream } from "effect" -import { HttpClientRequest, type HttpClientResponse } from "effect/unstable/http" +import type { HttpClientResponse } from "effect/unstable/http" import { Adapter } from "../adapter" import { capabilities, model as llmModel, type ModelInput } from "../llm" import { - InvalidRequestError, Usage, type CacheHint, type FinishReason, @@ -205,7 +204,7 @@ const decodeChunk = (data: string) => const encodeTarget = Schema.encodeSync(AnthropicTargetJson) const decodeTarget = Schema.decodeUnknownEffect(AnthropicMessagesDraft.pipe(Schema.decodeTo(AnthropicMessagesTarget))) -const invalid = (message: string) => new InvalidRequestError({ message }) +const invalid = ProviderShared.invalidRequest const baseUrl = (request: LLMRequest) => (request.model.baseURL ??

Schema additions on the Converse target: - BedrockImageBlock for { image: { format, source: { bytes } } }. Supported formats per Converse docs: png, jpeg, gif, webp. - BedrockDocumentBlock for { document: { format, name, source: { bytes } } }. Supported formats: pdf, csv, doc, docx, xls, xlsx, html, txt, md. - BedrockCachePointBlock for the positional { cachePoint: { type } } marker. Currently emits the only Bedrock cache type, 'default'. A TODO marks where to map ttlSeconds → ttl ('5m' | '1h') once we have a recorded cassette to validate the wire shape. Lowering: - TextPart and SystemPart cache hints emit a positional cachePoint marker right after their text block. Both 'ephemeral' and 'persistent' CacheHint types map onto Bedrock's 'default' since Bedrock does not distinguish — this matches the convention the Anthropic adapter uses (cache?.type === 'ephemeral' check). - MediaPart routes by mediaType: 'image/*' → image block, everything else → document block. MIME type → format mapping is via IMAGE_FORMATS / DOCUMENT_FORMATS records typed with 'as const satisfies' so the keys stay narrow at compile time. - A small textWithCache helper collapses the 'push text, push cachePoint if cache is set' pattern that would otherwise repeat at three callsites (system, user-text, assistant-text). - Bytes are encoded via ProviderShared.mediaBytes — the shared helper Kit landed in c3346f7dc. Bug fix: lowerSystem was dead code in the previous draft. The prepare() function still inlined the pre-cache .map(...) that discarded system cache hints. prepare() now calls lowerSystem so the cachePoint markers actually flow through. Tests (7 new fixtures, all green): - Cache hint on system / user-text / assistant-text emits cachePoint after text in each context. - No cache hint → no cachePoint emitted (regression guard). - Image lowering covers png / jpeg / jpg-alias / webp. - Uint8Array image bytes are base64-encoded ([1,2,3,4,5] → AQIDBAU=). - Document lowering with filename round-trip and missing-filename fallback to 'document.'. - Unsupported image MIME (image/svg+xml) is rejected with a clear error message. - Unsupported document MIME (application/x-tar) is rejected with a clear error message. Recorded cassettes for cache hints, images, and documents are still TODO — the wire shapes are exercised deterministically here and will be validated against a live model in a follow-up cassette pass. Verified: bun typecheck clean, 113 pass / 0 fail / 0 skip (was 106; +7 from the new fixture tests). --- packages/llm/src/provider/bedrock-converse.ts | 170 ++++++++++++++++- .../test/provider/bedrock-converse.test.ts | 172 +++++++++++++++++- 2 files changed, 332 insertions(+), 10 deletions(-) diff --git a/packages/llm/src/provider/bedrock-converse.ts b/packages/llm/src/provider/bedrock-converse.ts index 280a21860b49..e0042ee27b5d 100644 --- a/packages/llm/src/provider/bedrock-converse.ts +++ b/packages/llm/src/provider/bedrock-converse.ts @@ -7,9 +7,11 @@ import { Adapter } from "../adapter" import { capabilities, model as llmModel, type ModelInput } from "../llm" import { Usage, + type CacheHint, type FinishReason, type LLMEvent, type LLMRequest, + type MediaPart, type ProviderChunkError, type ToolCallPart, type ToolDefinition, @@ -49,6 +51,7 @@ export type BedrockConverseModelInput = Omit const BedrockToolUseBlock = Schema.Struct({ toolUse: Schema.Struct({ @@ -84,8 +87,66 @@ const BedrockReasoningBlock = Schema.Struct({ }), }) -const BedrockUserBlock = Schema.Union([BedrockTextBlock, BedrockToolResultBlock]) -const BedrockAssistantBlock = Schema.Union([BedrockTextBlock, BedrockReasoningBlock, BedrockToolUseBlock]) +// Image block.

The policy mirrors the AI-SDK applyCaching path (packages/opencode/src/provider/transform.ts:229): mark the first 2 system parts and the last 2 messages with an ephemeral cache hint, gated on `model.capabilities.cache.prompt`. Adapters lower the hint structurally — Anthropic emits `cache_control: { type: "ephemeral" }` on the marked block, Bedrock emits a positional `cachePoint: { type: "default" }` after the marked block (added in 9d7d518ac). The capability gate keeps non-cache adapters (OpenAI Responses, Gemini, OpenAI-compat Chat) hint-free. Why a Patch and not bridge code: - packages/llm/AGENTS.md TODO explicitly calls for cache hint patches - Other consumers of @opencode-ai/llm get caching for free - The bridge stays focused on shape conversion (MessageV2 \u2192 LLMRequest) - Patches compose via ProviderPatch.defaults (now includes this one) - The capability gate is a typed predicate, not provider-name matching Implementation: - New `cachePromptHints` patch in provider/patch.ts. The `withCacheOnLastText` helper uses Array.findLastIndex (codebase idiom) and short-circuits when no text part exists so messages with only tool-result content are returned identity-equal. - `EPHEMERAL_CACHE` is a single shared CacheHint instance — no per-request allocation, preserves `instanceof` for any consumer that checks class identity. - Added to `ProviderPatch.defaults` so existing callers that pass `defaults` get cache support automatically. Tests (5 new in patch.test.ts): - Marks first 2 system parts on cache-capable models. - Marks last text part of last 2 messages. - Targets the last text part when a message has trailing non-text content (assistant text + tool-call). - Returns content unchanged (identity-equal) when no text part exists, so pure tool-result messages don't allocate. - No-op when the model does not advertise prompt caching. Bridge cleanup: - Removed `applyCachePolicy`, `withCacheOnLastText`, `updateMessageContent`, `EPHEMERAL_CACHE` from llm-native.ts (-30 lines of bridge-side cache code). - Dropped now-unused `CacheHint`, `LLMRequest`, `Message` imports. - The bridge's only responsibility is now MessageV2 lowering; callers wire `patches: ProviderPatch.defaults` at client construction. OpenCode tests rewritten: - Old: assert on `request.system[N].cache` (bridge internals). - New: assert on `prepared.target` after running through `LLMClient.make({ adapters, patches: ProviderPatch.defaults }) .prepare(request)` — verifies the full lowering end-to-end. - Anthropic: target.system[0..1] carry `cache_control: ephemeral`, target.messages[1..2] carry it on the final text block. - Bedrock: target has `cachePoint` markers after each cached block. - Non-cache (OpenAI Responses): JSON.stringify(target) contains none of `cache_control` / `cachePoint` / `ephemeral`. Verified: bun typecheck clean across both packages, 120/0/0 in LLM package (was 113; +7 from new patch tests counting parameter variations), 21/0/0 in OpenCode native+bridge tests. --- packages/llm/src/provider/patch.ts | 49 +++++++- packages/llm/test/patch.test.ts | 115 ++++++++++++++++++ packages/opencode/src/session/llm-native.ts | 74 +++-------- .../opencode/test/session/llm-native.test.ts | 85 ++++++++----- 4 files changed, 236 insertions(+), 87 deletions(-) diff --git a/packages/llm/src/provider/patch.ts b/packages/llm/src/provider/patch.ts index 7aa8116a0370..75e2ede07063 100644 --- a/packages/llm/src/provider/patch.ts +++ b/packages/llm/src/provider/patch.ts @@ -1,4 +1,5 @@ -import { Model, Patch } from "../patch" +import { Model, Patch, predicate } from "../patch" +import { CacheHint } from "../schema" import type { ContentPart, LLMRequest } from "../schema" const schemaIntentKeys = [ @@ -103,6 +104,50 @@ export const sanitizeGeminiToolSchema = Patch.toolSchema("gemini.sanitize-tool-s }), }) -export const defaults = [removeEmptyAnthropicContent, scrubClaudeToolIds, scrubMistralToolIds, sanitizeGeminiToolSchema] +// Single shared CacheHint instance — the cache patch reuses this one object +// across every marked part.

The bridge now lowers `MessageV2.FilePart` on user messages into `LLM.MediaPart`, unblocking image and document inputs. The first pass supports `data:` URLs only — the inline base64 form most commonly produced by the OpenCode UI for pasted screenshots and attached files. `http(s):` and `file:` URLs are explicitly rejected with a clear error so a future fetch / filesystem-read path can plug in cleanly without regressing safety. Implementation: - New `lowerFilePart` helper extracts the base64 payload from a data URL via a single regex; failure yields a typed `UnsupportedContentError` carrying both the partType and a `reason` that includes the offending URL for debuggability. - New `lowerUserPart` dispatches user-side parts: text \u2192 `LLM.text`, file \u2192 `MediaPart`. Returns identity-empty for any unsupported part type the static gate would have caught. - `userMessage` is now `Effect.fnUntraced` so file conversion can yield typed errors. `lowerMessage` (the per-message dispatcher, renamed from `messages` to free the local name) cascades the Effect through the request flow via `Effect.forEach`. - `supportsPart` static gate now allows `file` parts on user messages. Assistant messages still reject file parts (the LLM IR's MediaPart isn't valid in assistant content for any adapter we ship today). - `UnsupportedContentError` gains an optional `reason` field that appends to the canonical message as `: `. Existing static-gate failures keep the same shape (no reason). Tests (3 new, 1 rewritten): - Image data URL with filename round-trips to MediaPart with base64-stripped data. - PDF data URL preserves filename and base64 payload. - `https:` URL rejected with an error mentioning both the file partType, the message ID, and the offending URL. - The pre-existing "fails instead of dropping unsupported native parts" test now uses a reasoning part on a user message (reasoning is valid for assistants only) since file parts with data URLs are no longer rejected by the static gate. Out of scope, intentional follow-ups: - HTTP/HTTPS URL fetching (would need HttpClient.HttpClient and a decision on caching, retries, size limits). - File path / file:// URL reading (would need FileSystem.FileSystem and a permission check against the session's working directory). - File parts on assistant messages (LLM IR doesn't model assistant-side media; defer until we hit a provider that needs it). - text/plain and application/x-directory file parts that the AI-SDK path converts to text inline at message-v2.ts:791 — for the bridge, those should be converted upstream before reaching LLMNative.request rather than handled here. Verified: bun typecheck clean, 28/0/0 across native + bridge tests (was 21; +7 from the FilePart additions plus the rewritten unsupported-parts test). --- packages/opencode/src/session/llm-native.ts | 61 +++- .../opencode/test/session/llm-native.test.ts | 276 +++++++++++++++++- 2 files changed, 319 insertions(+), 18 deletions(-) diff --git a/packages/opencode/src/session/llm-native.ts b/packages/opencode/src/session/llm-native.ts index a87aa40aa31f..506666dee53d 100644 --- a/packages/opencode/src/session/llm-native.ts +++ b/packages/opencode/src/session/llm-native.ts @@ -1,4 +1,4 @@ -import { LLM, type ContentPart, type Message as CoreMessage } from "@opencode-ai/llm" +import { LLM, type ContentPart, type MediaPart } from "@opencode-ai/llm" import { Effect, Schema } from "effect" import { ProviderLLMBridge } from "@/provider/llm-bridge" import * as EffectZod from "@/util/effect-zod" @@ -23,10 +23,12 @@ export class UnsupportedContentError extends Schema.TaggedErrorClass(value: T | undefined): value is T => value !== undefined -const textContent = (message: MessageV2.WithParts) => - message.parts.flatMap((part) => (part.type === "text" && !part.ignored ?

round-trip encrypted reasoning content through the bridge MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes audit gap #3. The bridge now extracts the encrypted reasoning blob from `MessageV2.ReasoningPart.metadata` and surfaces it on `LLM.ReasoningPart.encrypted`, where the Anthropic and Bedrock adapters lower it to the wire — Anthropic emits `thinking.signature`, Bedrock emits `reasoningContent.reasoningText.signature`. Without this, multi-turn sessions with reasoning models would lose the encrypted state on every step and break the chain. The encrypted blob originates in three different places depending on how the session was started: 1. AI-SDK Anthropic sessions store it as `metadata.anthropic.signature` (per AI SDK provider-keyed convention). 2. AI-SDK OpenAI sessions store it as `metadata.openai.reasoningEncryptedContent`. 3. Future LLM-native sessions will store it as a top-level `metadata.encrypted` string (cleanest shape — provider-agnostic, matches the LLM IR field name). The new `encryptedReasoning` helper probes all three locations in order, so existing OpenCode sessions can be served by the LLM-native path without re-recording reasoning content. The full `metadata` record continues to flow through to `LLM.ReasoningPart.metadata` unchanged, preserving any provider-specific fields adapters might read in the future. OpenAI Responses encrypted reasoning round-trip is intentionally out of scope: the LLM-package adapter doesn't yet model reasoning items in the request body. That's a separate adapter feature requiring new input-item schema variants and is deferred until needed. Tests (5 new in llm-native.test.ts): - AI-SDK Anthropic signature extracted into LLM.ReasoningPart.encrypted. - End-to-end Anthropic lowering: bridge \u2192 client.prepare \u2192 target with `thinking.signature` populated correctly. - AI-SDK OpenAI reasoningEncryptedContent extracted (forward compatibility — useful when the OpenAI Responses adapter gains reasoning-item lowering). - Top-level metadata.encrypted extracted (LLM-native session shape). - No known key in metadata leaves `encrypted` undefined. Verified: 33/0/0 across native + bridge tests (was 28; +5 from the new reasoning extraction tests). --- packages/opencode/src/session/llm-native.ts | 15 +- .../opencode/test/session/llm-native.test.ts | 149 ++++++++++++++++++ 2 files changed, 163 insertions(+), 1 deletion(-) diff --git a/packages/opencode/src/session/llm-native.ts b/packages/opencode/src/session/llm-native.ts index 506666dee53d..14875bc88162 100644 --- a/packages/opencode/src/session/llm-native.ts +++ b/packages/opencode/src/session/llm-native.ts @@ -47,6 +47,9 @@ export type RequestInput = { const isDefined = (value: T | undefined): value is T => value !== undefined +const isRecord = (value: unknown): value is Record => + typeof value === "object" && value !== null && !Array.isArray(value) + // Match `data:[;param=value]*[;base64],`.

H1: Inconsistent apiKey precedence. Five of six adapters spread the caller's headers first then set the auth header (apiKey wins), but `OpenAICompatibleChat.model` did the opposite (caller headers won). That meant a user passing both `apiKey` and `headers.authorization` would get auth from a different source depending on which adapter they routed through. Flip the OpenAI-compatible adapter to match the rest, and add a comment documenting the rule: apiKey wins, callers who want their own auth header should omit `apiKey` entirely. H4: Gemini tool-schema sanitization was split across two functions that both ran on every Gemini request — `convertJsonSchema` in the adapter (lossy projection: drop empty objects, derive nullable from type-array, allowlist of preserved keys, recursive properties/items) and `sanitizeGeminiSchemaNode` registered as a default `tool-schema` patch (fix-up: integer enums to strings, dangling required filtering, untyped array typing, scalar property stripping). Both passes only ran on Gemini models; debugging a tool schema rejection meant checking both files. Fold the patch's rules into the adapter as `sanitizeToolSchemaNode`, running before the existing projection step (renamed `projectToolSchemaNode`). Compose them in `convertToolSchema` and use that in `lowerTool`. Delete the patch from `provider/patch.ts` and `ProviderPatch.defaults`. The behavior is unchanged — same input, same output — but the rules now live in one file with a header comment explaining the two concerns. The matching test in `gemini.test.ts` no longer needs to opt into a patch list; it now asserts the adapter alone produces the sanitized shape. --- packages/llm/src/provider/gemini.ts | 119 ++++++++++++++---- .../src/provider/openai-compatible-chat.ts | 6 +- packages/llm/src/provider/patch.ts | 62 --------- packages/llm/test/provider/gemini.test.ts | 10 +- 4 files changed, 104 insertions(+), 93 deletions(-) diff --git a/packages/llm/src/provider/gemini.ts b/packages/llm/src/provider/gemini.ts index 96ec060c5f59..eff963f25fed 100644 --- a/packages/llm/src/provider/gemini.ts +++ b/packages/llm/src/provider/gemini.ts @@ -136,17 +136,13 @@ interface ParserState { readonly usage?: Usage } -const GeminiChunkJson = Schema.fromJsonString(GeminiChunk) -const GeminiTargetJson = Schema.fromJsonString(GeminiTarget) -const decodeChunkSync = Schema.decodeUnknownSync(GeminiChunkJson) - -const decodeChunk = (data: string) => - Effect.try({ - try: () => decodeChunkSync(data), - catch: () => ProviderShared.chunkError(ADAPTER, "Invalid Gemini stream chunk", data), - }) -const encodeTarget = Schema.encodeSync(GeminiTargetJson) -const decodeTarget = Schema.decodeUnknownEffect(GeminiDraft.pipe(Schema.decodeTo(GeminiTarget))) +const { encodeTarget, decodeTarget, decodeChunk } = ProviderShared.codecs({ + adapter: ADAPTER, + draft: GeminiDraft, + target: GeminiTarget, + chunk: GeminiChunk, + chunkErrorMessage: "Invalid Gemini stream chunk", +}) const invalid = ProviderShared.invalidRequest @@ -158,11 +154,89 @@ const mediaData = ProviderShared.mediaBytes const isRecord = (value: unknown): value is Record => typeof value === "object" && value !== null && !Array.isArray(value) +// Tool-schema conversion has two distinct concerns: +// +// 1.

M1: Five adapters duplicated the same six-line block: const ChunkJson = Schema.fromJsonString(Chunk) const TargetJson = Schema.fromJsonString(Target) const decodeChunkSync = Schema.decodeUnknownSync(ChunkJson) const encodeTarget = Schema.encodeSync(TargetJson) const decodeTarget = Schema.decodeUnknownEffect(Draft.pipe(Schema.decodeTo(Target))) const decodeChunk = (data) => Effect.try({...chunkError(...)}) Lift it into `ProviderShared.codecs({ adapter, draft, target, chunk, chunkErrorMessage })` returning `{ encodeTarget, decodeTarget, decodeChunk }`. The result drops directly into `Adapter.define`'s `validate` field (uses `validateWith` internally to map parse errors to InvalidRequestError). Adopted in OpenAI Chat, OpenAI Responses, Anthropic Messages, and Gemini. Bedrock has a custom event-stream `decodeChunk` that takes `unknown` (not `string`) so it keeps its inline codecs. M2: Four adapters defined an identical `ToolAccumulator` interface (`{ readonly id: string; readonly name: string; readonly input: string }`). Lift to `ProviderShared.ToolAccumulator`. Anthropic extends it locally with `providerExecuted` for hosted tools. M3: The five `mapUsage` implementations had subtly different `totalTokens` policies — OpenAI Chat passed through whatever the provider sent, OpenAI Responses unconditionally summed inputs and output (publishing `totalTokens: 0` when both were `undefined`), Anthropic and Gemini guarded with conditionals, Bedrock used a `(...) || undefined` falsy fallback. Add `ProviderShared.totalTokens` with one rule: prefer provider-supplied total, else sum inputs and outputs only when at least one is defined, else `undefined`. Fixes the OpenAI Responses `totalTokens: 0` bug. M6: Anthropic's `mergeUsage` recomputed `totalTokens` from the merged input/output via two nested ?? chains and a conditional sum. Simplified to use the same totalTokens helper, with `inputTokens` and `outputTokens` extracted as locals so the merge is one ?? per field and the comment explains why merging exists (Anthropic emits usage on `message_start` and `message_delta`). No behavior changes other than the OpenAI Responses fix; existing tests pass unchanged. 120 LLM-package tests + 33 OpenCode bridge tests green. --- .../llm/src/provider/anthropic-messages.ts | 41 +++++------- packages/llm/src/provider/bedrock-converse.ts | 14 +--- packages/llm/src/provider/openai-chat.ts | 33 ++++------ packages/llm/src/provider/openai-responses.ts | 34 ++++------ packages/llm/src/provider/shared.ts | 66 +++++++++++++++++++ 5 files changed, 110 insertions(+), 78 deletions(-) diff --git a/packages/llm/src/provider/anthropic-messages.ts b/packages/llm/src/provider/anthropic-messages.ts index 9589ca27c278..e069c1210ad2 100644 --- a/packages/llm/src/provider/anthropic-messages.ts +++ b/packages/llm/src/provider/anthropic-messages.ts @@ -179,10 +179,7 @@ const AnthropicChunk = Schema.Struct({ }) type AnthropicChunk = Schema.Schema.Type -interface ToolAccumulator { - readonly id: string - readonly name: string - readonly input: string +interface ToolAccumulator extends ProviderShared.ToolAccumulator { readonly providerExecuted: boolean } @@ -191,17 +188,13 @@ interface ParserState { readonly usage?: Usage } -const AnthropicChunkJson = Schema.fromJsonString(AnthropicChunk) -const AnthropicTargetJson = Schema.fromJsonString(AnthropicMessagesTarget) -const decodeChunkSync = Schema.decodeUnknownSync(AnthropicChunkJson) - -const decodeChunk = (data: string) => - Effect.try({ - try: () => decodeChunkSync(data), - catch: () => ProviderShared.chunkError(ADAPTER, "Invalid Anthropic Messages stream chunk", data), - }) -const encodeTarget = Schema.encodeSync(AnthropicTargetJson) -const decodeTarget = Schema.decodeUnknownEffect(AnthropicMessagesDraft.pipe(Schema.decodeTo(AnthropicMessagesTarget))) +const { encodeTarget, decodeTarget, decodeChunk } = ProviderShared.codecs({ + adapter: ADAPTER, + draft: AnthropicMessagesDraft, + target: AnthropicMessagesTarget, + chunk: AnthropicChunk, + chunkErrorMessage: "Invalid Anthropic Messages stream chunk", +}) const invalid = ProviderShared.invalidRequest @@ -363,24 +356,26 @@ const mapUsage = (usage: AnthropicUsage | undefined): Usage | undefined => { outputTokens: usage.output_tokens, cacheReadInputTokens: usage.cache_read_input_tokens ?? undefined, cacheWriteInputTokens: usage.cache_creation_input_tokens ?? undefined, - totalTokens: usage.input_tokens !== undefined || usage.output_tokens !== undefined - ?

H2: Bedrock used raw `JSON.parse` and `JSON.stringify` despite the package rule against ad-hoc JSON encoders. The in-loop parse on each event-stream frame goes through `ProviderShared.parseJson` (yielded inside `Effect.gen`); the `decodeChunk` error fallback uses `ProviderShared.encodeJson` instead of `JSON.stringify` for the raw field on `ProviderChunkError`. No behavior change — just channels JSON through the shared Schema-driven codec. H3: `BedrockConverse.toHttp` built a `baseHeaders` record with `content-type: application/json` and passed it through both auth paths. The bearer path called `jsonPost` with the raw model headers (no manual content-type), the SigV4 path used `baseHeaders` plus the signed result. Two paths produced subtly different header sets and both relied on `jsonPost` overwriting/adding the same content-type key. Simplify: drop the unused bearer-side construction; rename the SigV4 input to `headersForSigning` and document why content-type must be present at signing time (signature covers it). M4: Lift `isRecord` from `gemini.ts` into `ProviderShared.isRecord` so adapters share one definition. The duplicates in `llm.ts` (LLM IR layer) and `llm-native.ts` (OpenCode bridge) stay where they are — those are at different layers and importing from `provider/` would invert the dependency direction. Net effect: the provider layer goes from 2 copies to 1. L8: `TransportError` lost everything but the message string. Surface the originating reason tag (`Timeout` / `TransportError` / `ResponseError` / `RequestError`) and the request URL when available, both as optional Schema fields. Consumers that don't care keep getting the same `message` rendering; consumers that do can finally render "timed out connecting to https://..." instead of "HTTP transport failed". M9 + L3: Two dead branches. Anthropic's `processChunk` had `?? ""` fallbacks for `partial_json` after an early-return guard already proved it non-empty. OpenAI Chat's `mapFinishReason` had `if (reason === undefined || reason === null) return "unknown"` followed by `return "unknown"` — both branches went to the same place.

Behavior is gated and shipped off by default; only callers that opt in see any difference. The full migration plan (audit gap #4) is parallel-path-with-flag, prove parity test-by-test, flip default last. This commit is phase 1: get the wire-up in place behind a flag with one protocol so we can see whether the design holds before committing to the full migration. Wire-up summary: - New flag `OPENCODE_EXPERIMENTAL_LLM_NATIVE` (also enabled by the umbrella `OPENCODE_EXPERIMENTAL`). Off by default. - The session-LLM `live` layer now consumes `RequestExecutor.Service`, and the `defaultLayer` provides `RequestExecutor.defaultLayer` so a Node fetch HTTP client backs every native stream. - `runNative(input)` returns `Stream | undefined`. `undefined` means "fall through to AI SDK." It returns a real stream only when every gate passes: the flag is set, the caller populated `input.nativeMessages` (the bridge needs typed `MessageV2.WithParts`, not the AI SDK `messages` array), the session has zero tools (Phase 2 will lift this), and the bridge routes the model to a protocol in `NATIVE_PROTOCOLS`. - `NATIVE_PROTOCOLS` is a single-entry set today: `anthropic-messages`. Other adapters are imported and registered with the client so the Phase 2 expansion is a one-line edit, not an architecture change. - Stream wiring: client.stream(req) -> Stream.flatMap(event -> fromIterable(map.map(event))) -> Stream.concat(suspended fromIterable(map.flush())) -> Stream.provideService( RequestExecutor.Service, executor). The flush stream is built lazily with `Stream.unwrap(Effect.sync(...))` so it observes the mapper final state after every upstream event has been mapped. - The mapper (`LLMNativeEvents.mapper`) emits AI-SDK-shaped session events from `LLMEvent` so downstream consumers see one shape. What this does NOT do (deferred to later phases): - No tool support on the native path (skipped, falls through). - No parity harness yet; Phase 2 builds it. - No production traffic; flag is off by default and no production caller populates `nativeMessages`. - No reasoning/cache/multi-modal coverage. Anthropic supports reasoning and cache via existing patches, so those start working as soon as a caller routes a real session through.

The test stays self-contained: - Builds a fake Anthropic `Provider.Info` + `Provider.Model` via `ProviderTest`. - Builds an `LLMRequest` via `LLMNative.request(...)` from a `MessageV2.WithParts` user message — the same call shape `runNative` uses inside `session/llm.ts`. - Creates an `LLMClient` with the same adapters list + `ProviderPatch.defaults` list as `runNative`. The adapters are imported directly from `@opencode-ai/llm`; if `runNative`'s `NATIVE_ADAPTERS` array changes, this test's `adapters` constant has to follow (commented). - Provides a single fixed-response HTTP layer that returns a scripted Anthropic SSE body. The layer helper is inlined (12 lines) rather than imported from `packages/llm/test/lib/http.ts` so the test doesn't reach across package boundaries. - Pipes the LLM stream through `LLMNativeEvents.mapper()` exactly as `runNative` does (`Stream.flatMap` + lazy `Stream.concat` for flush), runs it to completion, and asserts the key session events: `text-start` precedes `text-delta`, `finish-step` carries `finishReason: "stop"`, and `finish` carries the merged usage totals. This does NOT test the dispatch gate inside `session/llm.ts` (`!Flag.OPENCODE_EXPERIMENTAL_LLM_NATIVE`, missing `nativeMessages`, tools present, non-Anthropic protocol). Those are simple boolean conditions and don't need separate coverage. It also does not exercise the production `Service` layer — that's deferred to Phase 2 step 2 (tool support) and Phase 2 step 3 (production caller wiring). What the test buys: confidence that the conversion pipeline works and catches regressions in `LLMNative.request`, the LLM adapter set, or `LLMNativeEvents.mapper` before they would surface in a real session.

The gate in `runNative` widens accordingly: a session can use the native path when it has zero tools (existing behavior) OR when it explicitly provides `nativeTools` matching its AI SDK `tools` (new opt-in). When `nativeTools` reaches `LLMNative.request`, the existing `toolDefinition` converter folds each `Tool.Def` into the request's `tools` array and the LLM core lowers it onto the wire. This commit deliberately does NOT include the dispatch loop. A session that opts in by setting `nativeTools` and that triggers a `tool-call` from the model will see the call event but no `tool-result` because the native path has no execute handler yet. That's why no production caller populates `nativeTools`: phase 2 step 2b will land the dispatch loop and only then will real production sessions route through here. What this lays in place: - `StreamInput.nativeTools` typed against `Tool.Def[]` from `@/tool`. Aliased to `OpenCodeTool` at the import to dodge a clash with the AI SDK `Tool` type that the same file already imports. - The `runNative` gate flips from "no tools allowed" to "either no tools, or `nativeTools` is supplied". An AI SDK tool count > 0 with `nativeTools` undefined still falls through, so existing production sessions are unaffected. - `LLMNative.request` already accepted `tools: ReadonlyArray` and converts via `toolDefinition`. We just forward the input through; no LLM-bridge change. Smoke coverage: a new test in `llm-native-stream.test.ts` builds a typed `Tool.Def` (Effect Schema parameters), routes it through `LLMNative.request` + `LLMClient.prepare`, and asserts the prepared Anthropic target carries the tool as an `input_schema` block with the expected JSON Schema shape. This validates the conversion path that phase 2 step 2b will exercise from inside `runNative`. Verification: opencode typecheck clean; 35/0/0 across the three bridge-area tests (`llm-native.test.ts`, `llm-native-stream.test.ts`, `llm-bridge.test.ts`). --- packages/opencode/src/session/llm.ts | 18 ++++++- .../test/session/llm-native-stream.test.ts | 50 ++++++++++++++++++- 2 files changed, 66 insertions(+), 2 deletions(-) diff --git a/packages/opencode/src/session/llm.ts b/packages/opencode/src/session/llm.ts index 8bb876e46015..49bb014327a8 100644 --- a/packages/opencode/src/session/llm.ts +++ b/packages/opencode/src/session/llm.ts @@ -22,6 +22,8 @@ import { Config } from "@/config/config" import { InstanceState } from "@/effect/instance-state" import type { Agent } from "@/agent/agent" import type { MessageV2 } from "./message-v2" +// Aliased to avoid a name clash with the AI SDK `Tool` type imported above. +import type { Tool as OpenCodeTool } from "@/tool" import { Plugin } from "@/plugin" import { SystemPrompt } from "./system" import { Flag } from "@opencode-ai/core/flag/flag" @@ -60,6 +62,13 @@ export type StreamInput = { retries?: number toolChoice?: "auto" | "required" | "none" nativeMessages?: ReadonlyArray + // Opcode-native `Tool.Def[]` parallel to `tools` (AI SDK shape).

When the gate-passing session has `nativeTools` populated, the native runner forks an AI SDK `tool.execute(...)` the moment a `tool-call` event arrives mid-stream and injects a synthetic `tool-result` event back into the same stream when the handler resolves. Long-running tools no longer block subsequent tool-call streaming; the user sees each result land as soon as that specific handler completes. The driver loops across rounds: when a round ends with `reason: "tool-calls"` AND the dispatchers produced at least one result, the runner builds a continuation `LLMRequest` (assistant message echoing text/reasoning/tool-call content + tool messages with results) and recurses. Stops on a non-`tool-calls` finish, when `maxSteps` (default 10, mirrors `ToolRuntime.run`) is reached, or when the underlying scope is interrupted. New file `session/llm-native-tools.ts`: - `runWithTools({ client, request, tools, abort, maxSteps? })` is the public entry point. Returns a `Stream` of merged model events + synthetic tool results, ready to flow through `LLMNativeEvents.mapper` for consumption by the existing session processor. - `runOneRound` is the internal building block. It opens an unbounded `Queue`, forks a producer that streams the model and pushes each event to the queue, and forks a dispatcher (via a scope-bound `FiberSet`) for every non-provider-executed `tool-call`. Each dispatcher's result is pushed back into the same queue. After the model stream completes, the producer awaits `FiberSet.awaitEmpty` and ends the queue; consumers see end-of-stream. A `Deferred` resolves alongside so the multi-round driver can decide whether to recurse. - `dispatchTool` wraps the AI SDK `tool.execute(input, { toolCallId, messages, abortSignal })` call. Unknown-tool and execute-throws paths produce `tool-error` events instead of failing the stream (mirrors `ToolRuntime.run`'s defect-vs-recoverable boundary), so the model can self-correct on the next round. Wired into `runNative` (`session/llm.ts`): when `input.nativeTools` is non-empty, the upstream becomes `LLMNativeTools.runWithTools(...)` instead of `nativeClient.stream(...)`; the AI SDK `tools` record flows in as the dispatch table. Zero-tool sessions still take the direct-stream path (one round, no dispatch overhead). Mapper update (`session/llm-native-events.ts`): `tool-result` events whose `result.value` matches the opencode `Tool.ExecuteResult` shape (`{ output: string, title?: string, metadata?: object }`) now flow through to the AI-SDK-shaped session event with their `title` and `metadata` preserved. Provider-executed and synthetic results that don't match still fall back to `stringifyResult`. Without this, the session processor would see every native tool result as `{ title: "", metadata: {}, output: }`. Smoke test (`test/session/llm-native-stream.test.ts`): scripts a two-round Anthropic SSE backend — round 1 issues a `lookup` tool call, round 2 replies with text after the tool result feeds back. Asserts the full event sequence threads through `runWithTools`, the dispatcher, and the mapper: - `tool-call` event has the streamed JSON input parsed. - `tool-result` event carries the `ExecuteResult` shape with `title` + `output` populated (proving the mapper update works). - Round 2 text-delta arrives after the synthetic tool-result. - Final `finish` event has `finishReason: "stop"` (loop terminated). What this still does NOT do (deferred to step 3): - No production caller populates `nativeTools` yet; that's the `prompt.ts:resolveTools` change. Until that lands, the gate keeps every real session on the AI SDK path. - No parity harness comparing native + AI SDK event sequences for the same scripted session. That's step 4.

With `OPENCODE_EXPERIMENTAL_LLM_NATIVE=1` set, real production sessions that satisfy the gate now stream through `LLMNativeTools.runWithTools` instead of `streamText` — the LLM-native path goes from "plumbing-only" to "actually used." Changes: - `prompt.ts:resolveTools` collects `Tool.Def[]` from the registry loop and tracks a feasibility flag. MCP tools (which only have AI SDK shape) flip the flag off; the synthesized `StructuredOutput` tool that the json_schema branch injects also flips it. The return shape becomes `{ tools, nativeTools }` where `nativeTools` is `undefined` whenever any non-registry tool source contributes — callers fall through to the AI SDK path automatically. The registry path stays in sync because every `tools[item.id] = tool({...})` is paired with a `nativeTools.push(item)` at the same loop iteration. - The single caller (`prompt.ts:1396`) destructures the new shape and passes `nativeTools` through to `handle.process(...)`. The json_schema branch sets `nativeTools = undefined` after injecting `StructuredOutput` so the gate falls through for structured-output sessions. - `runNative` (in `session/llm.ts`) gains two safety nets that work regardless of caller behavior: 1. Coverage check: if AI SDK tools are non-empty, every key must have a matching `Tool.Def` in `nativeTools`. A partial set falls through. Defends against future callers that might emit a partial native list. 2. Filter parity: `runNative` now calls the existing `resolveTools(input)` (the in-file permission/user-disabled filter) and intersects its keys with `nativeTools`, then feeds the filtered AI SDK record to the dispatcher and the filtered native list to `LLMNative.request`. Without this, sessions could see permission-disabled tools advertised on one path but not the other. - The dispatch path uses the filtered AI SDK tools record as the execute table: `LLMNativeTools.runWithTools({ tools: filteredAITools, ... })`. Tool definitions sent to the model are the filtered native list. Every tool the model sees can dispatch. What this enables: a session opted into the experimental flag, with a clean toolset (registry-only, no MCP, no structured output), running an Anthropic model, now exercises the streaming-dispatch loop end-to-end. Tool calls fire as soon as the model finishes streaming each tool's input; results land in the stream the moment each handler resolves. Multi-round behavior matches phase 2 step 2b. What this still does NOT do (deferred to step 4): - Parity test harness comparing native vs AI SDK event sequences for the same scripted session. Until that lands, broader confidence comes from running real sessions with the flag set. - MCP support on the native path. Sessions with MCP servers configured stay on AI SDK indefinitely. - Native support for the synthesized `StructuredOutput` tool. Verification: opencode typecheck clean for `src/session/*` (the TUI-side errors visible in the working tree are Kit's parallel work, untouched here); bridge area tests 36/0/0 across `llm-native.test.ts` + `llm-native-stream.test.ts` + `llm-bridge.test.ts`; `prompt.test.ts` still 47/0/0 (no regression from the resolveTools shape change). --- packages/opencode/src/session/llm.ts | 43 +++++++++++++++++++------ packages/opencode/src/session/prompt.ts | 27 ++++++++++++++-- 2 files changed, 58 insertions(+), 12 deletions(-) diff --git a/packages/opencode/src/session/llm.ts b/packages/opencode/src/session/llm.ts index 988b5bbac707..22d97099f738 100644 --- a/packages/opencode/src/session/llm.ts +++ b/packages/opencode/src/session/llm.ts @@ -488,13 +488,36 @@ const live: Layer.Layer< const runNative = Effect.fn("LLM.runNative")(function* (input: StreamRequest) { if (!Flag.OPENCODE_EXPERIMENTAL_LLM_NATIVE) return undefined if (!input.nativeMessages || input.nativeMessages.length === 0) return undefined - // Tools without dispatch wiring would mean the model issues tool-call - // events that never get a tool-result.

Start with AI SDK pure lowering tests for OpenAI-compatible and OpenAI - Responses. Convert their inputs into `LLMRequest` fixtures and snapshots into - provider target snapshots. -2. Use AI SDK stream/model tests to build provider chunk fixtures for OpenAI - Chat and Responses. -3. Use Pi tests for regression cases AI SDK does not cover, especially - cross-provider handoff, tool ID normalization, media in tool results, - reasoning signatures, and cache behavior. -4. Keep live/e2e tests optional behind env vars. The package's required test - suite should be deterministic and fixture-based. - -## Prior art - -### AI SDK - -AI SDK's provider architecture is mature and worth studying. It is not "bad" -code, but it is shaped by a broad public API, browser/server use cases, UI -helpers, provider package compatibility, telemetry, callbacks, retries, tools, -and legacy evolution. That makes the code heavier than what this package should -start with. - -Useful ideas to borrow: - -- A narrow provider interface. `LanguageModelV3` has `doGenerate` and - `doStream`, plus provider/model identity and supported URL metadata. -- A standardized provider prompt separate from user-facing prompt inputs. -- A standardized stream-part union with text, reasoning, tool input, tool calls, - files, sources, metadata, finish, raw, and error parts. -- Provider-specific request lowering isolated in provider packages. -- Tool preparation separated from tool execution. -- Tool execution as a stream transformation that can delay finish until tool - results are emitted. -- Test-server and fixture-heavy provider tests. -- Explicit `providerOptions` and `providerMetadata` escape hatches. -- Stream parts for partial tool input, not just final tool calls. - -Things to avoid copying directly: - -- A very large `streamText` orchestration surface that mixes prompt - standardization, retries, telemetry, callbacks, tool loops, result promises, - UI streams, and output parsing. -- User-facing UI message concerns in the core model package. -- Wide provider option bags as the main extensibility mechanism. -- Heavy overload/type gymnastics for public SDK ergonomics before the internal - algebra is stable. -- Direct `ReadableStream`-first internals when Effect `Stream` can keep errors, - interruption, scope, and services explicit. - -The best AI SDK lesson is: keep the provider contract small, but expect the -orchestration layer to grow if tool execution, UI streams, callbacks, retries, -and structured output all live in one function. This package should split those -concerns from the beginning. - -### Effect Smol unstable AI - -Effect Smol's `effect/unstable/ai` modules are closer to the desired shape. -Relevant files live under `../effect-smol/packages/effect/src/unstable/ai`. - -Useful ideas to borrow: - -- `Prompt` and `Response` are Schema-owned domain models with encoded and - decoded representations. -- `Tool` and `Toolkit` use Schema for parameters, success, and failure outputs, - then decode inputs and encode outputs at execution boundaries. -- `LanguageModel.make` separates provider implementations from higher-level - generation and stream orchestration. -- `Response.StreamPart(toolkit)` builds a stream-part schema that is specialized - by the active toolkit. -- `disableToolCallResolution` makes tool execution optional instead of forcing - one runtime policy. -- `CodecTransformer` is exactly the right abstraction for provider-specific - structured-output schema rewriting. -- `OpenAiStructuredOutput` and `AnthropicStructuredOutput` show how to transform - Effect Schema ASTs while preserving decoded types. -- `ResponseIdTracker` is a small focused service for incremental prompts and - previous response IDs. -- Tests use `withLanguageModel(...)` to inject fake model services without - mocking the whole world. - -Things to avoid copying directly: - -- The high-level `LanguageModel` and `Chat` APIs are broad application APIs, not - just a provider adapter core. -- Some type-level machinery is optimized for public Effect ergonomics and may be - too heavy for a first prototype. -- The unstable AI modules do not solve all provider-native lowering and patch - needs; they provide a strong domain/runtime shape, not a full replacement for - provider adapters. - -Most important Effect Smol inspiration: schemas should be executable contracts, -not documentation. Prompt parts, response parts, tool params/results, structured -output codecs, and provider chunks should all be decoded or encoded at explicit -boundaries. - -## Ideal testing strategy - -The test suite should be a pyramid with deterministic tests at the base and a -small number of live provider tests at the top. - -```text -many: schema, lowering, patch, parser, event, property tests -some: adapter contract tests with recorded chunks/responses -few: live provider smoke tests behind env vars -rare: cross-provider e2e handoff tests -``` - -### Unit and fixture tests - -Most tests should be ordinary unit tests over pure data. - -These are the core tests: - -- Decode valid and invalid `LLMRequest` values with Effect Schema. -- Lower `LLMRequest` fixtures into provider target drafts. -- Validate drafts into provider target ASTs. -- Snapshot final redacted provider request bodies. -- Apply patch plans and snapshot patch traces. -- Decode provider stream chunks from captured fixtures. -- Raise decoded chunks into `LLMEvent` sequences. -- Normalize usage from provider payloads. -- Parse partial tool-call JSON into stable input events. -- Verify tool schema sanitation for providers like Gemini. -- Verify media routing for user input and tool results. - -These tests should not hit the network. They should run fast and be safe in CI. - -### Adapter contract tests - -Every adapter should share the same contract test suite where possible. - -Contract cases: - -- text-only request lowers to valid target and emits text events -- tool-call request lowers tools and emits tool input/call events -- reasoning request emits reasoning events when chunks contain reasoning -- usage payload normalizes into `Usage` -- provider error payload normalizes into `ProviderRequestError` or - `ProviderErrorEvent` -- malformed chunks produce `ProviderChunkError` -- terminal provider event ends the stream even if the body remains open -- aborting the stream interrupts parsing and transport cleanly - -The contract suite can be parameterized by adapter: - -```ts -runAdapterContractTests({ - name: "openai-chat", - adapter: OpenAIChatAdapter, - fixtures: OpenAIChatFixtures, -}) -``` - -Adapter-specific tests still exist for native weirdness, but the shared contract -prevents every provider from inventing its own semantics. - -### Property tests - -Property tests help for algebra and parsing invariants. They are not a -replacement for provider fixtures because provider APIs have many arbitrary -rules. Use them where the property is ours. - -Good property-test targets: - -- Patch planning is deterministic regardless of input patch array order when - `phase`, `order`, and `id` are fixed. -- Empty patch plan is identity. -- Patch-plan composition is associative for pure patches. -- Idempotent patches remain idempotent. -- Patch traces are stable and contain exactly the selected patches. -- Target builder `concat` is associative for slots that claim monoidal behavior. -- `append-keyed` rejects duplicate keys or keeps a deterministic winner, - depending on the declared law. -- Header merge is case-insensitive. -- JSON schema sanitation is idempotent. -- Tool-call ID normalization always produces provider-legal IDs and avoids - collisions for a generated corpus. -- SSE parser handles arbitrary chunk boundaries. -- Text/event streams split across arbitrary byte boundaries decode to the same - event sequence as unsplit streams. -- Partial JSON parser never throws for arbitrary prefixes; it returns either a - partial object, empty object, or typed parse error. - -Libraries to consider: - -- `fast-check` is the pragmatic TypeScript choice. -- Effect's test/schema tooling can help generate schema-shaped values if that - becomes ergonomic enough locally. - -Property tests to avoid: - -- Do not generate arbitrary provider request bodies and assert provider behavior. - The provider behavior is not algebraic and will produce noisy tests. -- Do not snapshot property-generated values. Assert laws and invariants instead. -- Do not make property tests depend on network calls. - -### Golden fixture tests - -Golden tests should cover provider-native inputs and outputs that are easy to -break accidentally. - -Fixture layout: - -```text -test/fixture/ - openai-chat/ - text.request.json - text.stream.sse - text.events.json - tool-call.request.json - tool-call.stream.sse - tool-call.events.json - openai-responses/ - anthropic/ - gemini/ -``` - -Golden tests should store redacted provider requests and captured stream bodies, -not secrets or full live transcripts. When a provider changes, update fixtures -deliberately and keep a note about the upstream behavior change. - -### Live integration tests - -Live provider tests are useful but should be few, explicit, and optional. - -Use live tests for: - -- proving credentials/auth/headers work -- detecting provider API drift not represented in fixtures -- smoke-testing one text-only request per major protocol -- smoke-testing one tool-call request for OpenAI Chat, OpenAI Responses, and - Anthropic -- validating cache/reasoning behavior that cannot be trusted from static - fixtures - -Live test rules: - -- Skip unless the required env vars are present. -- Use cheap models and tiny prompts. -- Assert structural behavior, not exact wording. -- Use generous timeouts but keep the number of live tests small. -- Never run live tests in default PR CI unless explicitly configured. -- Record sanitized request/response fixtures from live tests when adding a new - regression. - -Example live test categories: - -- `OPENAI_API_KEY`: OpenAI Chat text and tool call -- `OPENAI_RESPONSES_API_KEY`: Responses text, reasoning metadata if available -- `ANTHROPIC_API_KEY`: Anthropic text, tool call, cache metadata smoke -- `GOOGLE_API_KEY`: Gemini text and schema/tool smoke -- `OPENROUTER_API_KEY`: OpenAI-compatible proxy smoke - -### Cross-provider tests - -Cross-provider handoff is important for coding agents because histories can move -between models. These tests should mostly be deterministic fixtures. - -Important cases: - -- OpenAI Responses tool-call IDs replayed into OpenAI Chat-compatible providers. -- Copilot/OpenAI tool-call IDs replayed into Anthropic. -- Gemini thought signatures preserved when returning to Gemini. -- Tool results with images replayed into providers that do and do not support - media in tool results. -- Reasoning content replayed into providers that require native reasoning fields. -- Histories with interrupted/pending tool calls converted into valid provider - histories. - -Only a very small subset of cross-provider tests should be live. Most should use -captured histories and assert target request validity. - -### Mutation and differential tests - -During migration from AI SDK, differential tests are valuable. - -For providers still backed by AI SDK, compare: - -- our lowered target request vs AI SDK lowered request where observable -- our event stream vs AI SDK full-stream event sequence for captured chunks -- our usage normalization vs AI SDK usage normalization - -This does not mean copying AI SDK behavior forever. It gives us a migration -guardrail while replacing the abstraction. - -Mutation-style checks can be simple: - -- Remove a required patch from the selected patch set and assert a fixture fails - target validation or violates an expected target snapshot. -- Corrupt a stream chunk and assert a typed chunk error. -- Remove a tool result from history and assert the prompt patch repairs or - rejects the history according to protocol rules. - -### What to optimize for - -Prioritize tests that catch these failures: - -- Provider 400s caused by subtly invalid message ordering. -- Tool call arguments streaming incorrectly or failing to parse partial JSON. -- Tool call IDs invalid for the next provider. -- Reasoning/thinking fields omitted or sent to the wrong native path. -- Cache-control metadata attached at the wrong level. -- Media routed into tool results for providers that reject it. -- Token usage double-counting cached or reasoning tokens. -- Streams hanging after a provider terminal event. -- Abort not cancelling transport or parser work. -- Config/native extension patches mutating undeclared target paths. - -The ideal default suite is many deterministic tests plus property tests for our -own algebra. Live requests are a smoke/regression layer, not the main source of -confidence. - -## MVP plan - -### Phase 1: Package skeleton and schemas - -Goal: define the standalone API without touching opencode runtime behavior. - -1. Add `packages/llm` with no imports from opencode session modules. -2. Add `schema.ts` with `ModelRef`, `LLMRequest`, `Message`, `ContentPart`, - `ToolDefinition`, `LLMEvent`, `Usage`, and errors. -3. Add `target.ts` with `TargetBuilder`, `TargetFragment`, and `TargetSlot`. -4. Add `patch.ts` with `Patch`, `PatchContext`, ordering, apply helpers, and - traces. -5. Add schema decoding tests for valid and invalid requests/events. - -Acceptance criteria: - -- The package compiles independently. -- No session-specific types are imported. -- A consumer can construct and validate an `LLMRequest`. - -### Phase 2: OpenAI Chat adapter without tool execution - -Goal: prove lowering, target fragments, transport, SSE parsing, and event -raising for the simplest useful protocol. - -1. Add `provider/openai-chat.ts` with `OpenAIChatDraft`, `OpenAIChatRequest`, and - chunk schemas. -2. Lower system parts, messages, generation options, and tools into a draft. -3. Validate the draft into a provider target with Effect Schema. -4. Implement SSE parsing from `Response` to decoded chunks. -5. Raise chunks into text, tool-input, tool-call, usage, and finish events. -6. Test entirely from captured fixture chunks and target snapshots. - -Acceptance criteria: - -- A text-only fixture produces the expected `LLMEvent` sequence. -- A tool-call fixture assembles partial JSON input into one `tool-call` event. -- Target snapshots show provider-native OpenAI Chat payloads. - -### Phase 3: Patch engine with real quirks - -Goal: validate composability against known exceptions. - -1. Implement prompt patches for unsupported media and empty content. -2. Implement schema patch for Gemini JSON Schema sanitation as a protocol-neutral - schema transformer. -3. Implement target patches for OpenAI-compatible usage, Alibaba thinking, and - GPT-5 defaults. -4. Attach patch traces to prepared requests and provider request errors. -5. Test patch selection against synthetic `ModelRef` fixtures. - -Acceptance criteria: - -- Patches can be selected by provider, protocol, model ID, capabilities, and - request flags. -- Patch traces are deterministic and snapshot-tested. -- Conflicting fragments can be detected by the target builder. - -### Phase 4: Optional tool runtime - -Goal: prove the package can provide an AI SDK-like loop without forcing every -consumer to use it. - -1. Add `tool-runtime.ts` with max step handling. -2. Execute `ExecutableTool`s when tool calls are emitted. -3. Append tool result messages and continue the stream. -4. Surface tool execution failures as `tool-error` events. -5. Keep permission, UI, and persistence decisions outside the package. - -Acceptance criteria: - -- In-memory tool fixtures can complete a two-step tool-call conversation. -- Consumers can still choose to manually handle tool calls without the runtime. - -### Phase 5: Opencode integration adapter - -Goal: use the package from opencode without migrating every provider. - -1. Add a small translator from opencode's current session state into - `LLMRequest` outside the package. -2. Add a translator from `LLMEvent` into current session processor events outside - the package if needed. -3. Gate native OpenAI Chat behind an experimental config flag. -4. Keep AI SDK as the default path during evaluation. -5. Compare request payloads and event sequences for simple prompts and tool - calls. - -Acceptance criteria: - -- The package remains session-agnostic. -- Native OpenAI Chat can run one real request behind a flag. -- Existing AI SDK behavior remains the default fallback. - -### Phase 6: Add more protocols - -Goal: prove the abstractions hold for less uniform providers. - -Order: - -1. OpenAI Responses for GPT-5 and OAuth-like flows. -2. Anthropic Messages for thinking, cache control, and strict tool rules. -3. Gemini for schema sanitation and thinking config. -4. Bedrock once Anthropic and Gemini target ASTs are stable. - -Acceptance criteria: - -- Each protocol has target schemas, chunk schemas, fixture tests, and patch - tests. -- Provider-specific weirdness lives in adapter-local lowerers or named patches. -- No consumer code branches on provider internals to build request payloads. - -## MVP defaults - -Use these defaults unless implementation proves they are wrong. - -- Keep the first version in `packages/llm`; do not move package-generic code back - into `packages/opencode` during integration. -- Treat patch IDs as internal until config, plugin, or public docs reference them. - Once referenced externally, require stable IDs and deprecation notes. -- Keep `ModelRef.native` and `LLMRequest.native` as - `Schema.Record(Schema.String, Schema.Unknown)` for the MVP, but decode every - consumed native value through adapter-owned schemas before use. -- Prefer native structured output when an adapter has strong fixture coverage for - that model/protocol. Prefer forced tool calls for providers where native JSON - schema is known to be brittle. -- Leave retries outside the package for the MVP. The transport abstraction should - make retries injectable later without changing adapters. -- Pass resolved auth headers in `ModelRef.headers` or `TransportContext`. - Adapters may add protocol headers like beta flags, but should not discover - credentials. -- Expose raw provider chunks only through debug hooks and fixture helpers, not as - required consumer events. Stable consumers should depend on `LLMEvent` plus - patch traces. -- Make `stream` the only required adapter runtime path. Implement `generate` by - accumulating `LLMEvent`s so streaming and non-streaming behavior cannot drift. -- Keep tool execution opt-in. The default adapter stream ends at tool-call events - and finish events; `ToolRuntime` is a helper layered above it. - -## Migration risks - -The main migration risk is not type modeling. It is behavioral parity around -provider-specific invalid histories and streaming edge cases. - -High-risk areas: - -- Cross-provider replay of historical tool calls and tool results. -- Partial tool input JSON and providers that emit missing or malformed args. -- Reasoning/thinking content that must be preserved for one provider and removed - or converted for another. -- Cache-control metadata attached at message vs content-block vs provider-option - level. -- Streams that emit finish markers before the HTTP body closes. -- Usage accounting with cached input, output, and reasoning token fields. -- Provider-specific schema sanitation, especially Gemini/OpenAPI-like schemas. - -Mitigation: - -- Start with OpenAI Chat because the request shape is simple and opencode already - relies heavily on OpenAI-compatible providers. -- Add OpenAI Responses second because it exercises IDs, reasoning, item-style - input, and modern GPT-5 behavior. -- Convert current `src/provider/transform.ts` branches into named patches one at - a time. Each extracted patch needs a fixture before removing the old branch. -- Run differential tests against AI SDK fixtures during migration, but do not make - AI SDK parity a permanent product requirement. -- Keep the current AI SDK path as the default until a native adapter has fixture - parity for text, tools, reasoning, abort, usage, and provider errors. - -## First implementation slice - -The smallest useful implementation should be docs-to-code mechanical. - -1. Create `packages/llm/src/schema.ts` with only schemas and errors. -2. Create `packages/llm/src/patch.ts` with pure patch planning and trace tests. -3. Create `packages/llm/src/target.ts` with the minimal `TargetBuilder` interface. Add - fragments only when a real adapter needs them. -4. Create `packages/llm/src/adapter.ts` with the shared runner but no real provider. -5. Add a fake adapter and in-memory transport contract test. -6.

Combine them with `RECORD=true` when refreshing only one provider or scenario. + **Binary response bodies.** Most providers stream text (SSE, JSON). AWS Bedrock streams binary AWS event-stream frames whose CRC32 fields would be mangled by a UTF-8 round-trip — those bodies are stored as base64 with `bodyEncoding: "base64"` on the response snapshot. Detection is by `Content-Type` in `@opencode-ai/http-recorder` (currently `application/vnd.amazon.eventstream` and `application/octet-stream`); cassettes for SSE/JSON adapters omit the field and decode as text. **Matching strategies.** Replay defaults to structural matching, which finds an interaction by comparing method, URL, allow-listed headers, and the canonical JSON body. This is the right choice for tool loops because each round's request differs (the message history grows). For scenarios where successive requests are byte-identical and expect different responses (retries, polling), pass `dispatch: "sequential"` in `RecordReplayOptions` — replay then walks the cassette in record order via an internal cursor. `scriptedResponses` (in `test/lib/http.ts`) is the deterministic counterpart for tests that don't need a live provider; it scripts response bodies in order without reading from disk. diff --git a/packages/llm/test/provider/anthropic-messages.recorded.test.ts b/packages/llm/test/provider/anthropic-messages.recorded.test.ts index d3af483402ff..4d83f13b52f6 100644 --- a/packages/llm/test/provider/anthropic-messages.recorded.test.ts +++ b/packages/llm/test/provider/anthropic-messages.recorded.test.ts @@ -43,6 +43,8 @@ const toolRequest = LLM.request({ const recorded = recordedTests({ prefix: "anthropic-messages", + provider: "anthropic", + protocol: "anthropic-messages", requires: ["ANTHROPIC_API_KEY"], options: { requestHeaders: ["content-type", "anthropic-version"] }, }) @@ -59,7 +61,7 @@ describe("Anthropic Messages recorded", () => { }), ) -

Examples: OpenAI Chat, Anthropic Messages, Bedrock Converse. - Endpoint — URL construction (baseURL + path + query params). - Auth — per-request transport authentication. Defaults to passthrough for adapters whose auth header is baked into model.headers. - Framing — byte stream to frames (SSE today; AWS event stream next). Adds Adapter.fromProtocol(...) which composes these into the existing AdapterDefinition shape so LLMClient.make(...) and the runtime registry do not change.

They own provider-native schemas and conversion logic. For example, `OpenAIChat.adapter` owns the OpenAI Chat target schema, OpenAI SSE chunk schema, message lowering, tool-call parsing, usage mapping, and finish-reason mapping. +An adapter is the registered, runnable composition of four orthogonal pieces: -Adapters should stay boring and typed: +- **`Protocol`** (`src/protocol.ts`) — semantic API contract. Owns request lowering, target validation, body encoding, and the streaming chunk-to-event state machine. Examples: `OpenAIChat.protocol`, `OpenAIResponses.protocol`, `AnthropicMessages.protocol`, `Gemini.protocol`, `BedrockConverse.protocol`. +- **`Endpoint`** (`src/endpoint.ts`) — URL construction. Receives the request and the validated target so it can read `model.id`, `model.baseURL`, `model.native.queryParams`, and any target field that influences the URL (e.g. Bedrock's `modelId` segment). Reach for `Endpoint.baseURL({ default, path })` before hand-rolling a URL. +- **`Auth`** (`src/auth.ts`) — per-request transport authentication. Most adapters use `Auth.passthrough`: their auth header is statically baked into `model.headers` by their `model()` constructor. Adapters that need per-request signing (Bedrock SigV4, future Vertex IAM, Azure AAD) implement `Auth` as a function that signs the body and merges signed headers into the result. +- **`Framing`** (`src/framing.ts`) — bytes → frames. SSE (`Framing.sse`) is shared; Bedrock keeps its AWS event-stream framing as a typed `Framing` value alongside its protocol. -- `prepare` lowers common `LLMRequest` into a provider draft. -- target patches mutate that draft before validation. -- `validate` validates the final provider target with Schema. -- `toHttp` creates the `HttpClientRequest`. -- `parse` decodes provider chunks into `LLMEvent`s. The shared `ProviderShared.framed` helper handles transport-error mapping, chunk decoding, and stateful chunk-to-event raising; adapters supply a `framing` step (bytes → frames), a `decodeChunk`, and a `process` callback that produces events. +Compose them via `Adapter.fromProtocol(...)`: -The transport is HTTP today, with two framing dialects: +```ts +export const adapter = Adapter.fromProtocol({ + id: "openai-chat", + provider: "openai", + protocol: OpenAIChat.protocol, + endpoint: Endpoint.baseURL({ default: "https://api.openai.com/v1", path: "/chat/completions" }), + framing: Framing.sse, +}) +``` + +The four-axis decomposition is the reason DeepSeek, TogetherAI, Cerebras, Baseten, Fireworks, and DeepInfra all reuse `OpenAIChat.protocol` verbatim — each provider deployment is a 5-15 line `Adapter.fromProtocol(...)` call instead of a 300-400 line adapter clone. Bug fixes in one protocol propagate to every consumer of that protocol in a single commit. + +Reach for the lower-level `Adapter.define(...)` only when an adapter genuinely cannot fit the four-axis model. New adapters should always start with `Adapter.fromProtocol(...)` and prove they need otherwise. -- **SSE** for OpenAI Chat / OpenAI Responses / Anthropic Messages / Gemini / OpenAI-compatible Chat. Use `ProviderShared.sse(...)` — a thin wrapper around `framed` with `sseFraming` (decode bytes → `Sse.decode` → drop `[DONE]` and Retry control events). -- **AWS event stream** for Bedrock Converse. Bedrock supplies its own `eventStreamFraming` step that runs `@smithy/eventstream-codec` against a cursor-based byte buffer. +When a provider ships a non-HTTP transport (OpenAI's WebSocket-based Codex backend, hypothetical bidirectional streaming APIs), the seam is `Framing` plus a parallel `Endpoint` / `Auth` interpretation — not a fork of the adapter contract. + +### Folder layout + +``` +packages/llm/src/ + schema.ts // LLMRequest, LLMEvent, errors — canonical Schema model + llm.ts // request constructors and convenience helpers + adapter.ts // Adapter.fromProtocol + LLMClient.make + executor.ts // RequestExecutor service + transport error mapping + patch.ts // Patch system (request/prompt/tool-schema/target/stream) + + protocol.ts // Protocol type + Protocol.define + endpoint.ts // Endpoint type + Endpoint.baseURL + auth.ts // Auth type + Auth.passthrough + framing.ts // Framing type + Framing.sse + + provider/ + shared.ts // ProviderShared toolkit used inside protocol impls + patch.ts // ProviderPatch helpers (defaults, capability gates) + openai-chat.ts // protocol + adapter (compose OpenAIChat.protocol) + openai-responses.ts + anthropic-messages.ts + gemini.ts + bedrock-converse.ts + openai-compatible-chat.ts // adapter that reuses OpenAIChat.protocol + openai-compatible-family.ts // family lookups (deepseek, togetherai, ...) + azure.ts / amazon-bedrock.ts / google.ts / ... // ProviderResolver entries + + provider-resolver.ts // OpenCode-bridge resolver layer + tool.ts // typed tool() helper + tool-runtime.ts // ToolRuntime.run with full tool-loop type safety +``` -When a provider ships a non-HTTP transport (OpenAI's WebSocket-based Codex backend, hypothetical bidirectional streaming APIs), it should land as a sibling adapter with a `toWs` (or analogous) producer + a `parse` that reads frames from that transport — not by leaking transport details into core types. The `framed` helper's `framing` parameter is the seam for new wire formats; the rest of the stream pipeline (terminal-error normalization, `mapAccumEffect` state, `onHalt` fallback) is already shared. +The dependency arrow points down: `provider/*.ts` files import `protocol`, `endpoint`, `auth`, `framing` and never the other direction.

Reach for it before hand-rolling a `Stream` chain. -- `sse({ ... })` — convenience wrapper for SSE adapters. Identical shape to `framed` minus the `framing` field. -- `sseFraming` — the SSE-specific framing step, exposed in case an adapter wants to wrap or compose it. -- `joinText(parts)` — joins an array of `TextPart` (or anything with a `.text`) with newlines. Use this anywhere an adapter flattens text content into a single string for a provider field. +- `framed({ adapter, response, readError, framing, decodeChunk, initial, process, onHalt? })` — the canonical streaming pipeline used by `Adapter.fromProtocol(...)`. You rarely call this directly anymore. +- `sseFraming` — the SSE-specific framing step.

Use this anywhere a protocol flattens text content into a single string for a provider field. - `parseToolInput(adapter, name, raw)` — Schema-decodes a tool-call argument string with the canonical "Invalid JSON input for `` tool call ``" error message. Treats empty input as `{}`. Use this in `finishToolCall` / `finalizeToolCalls`; do not roll a fresh `parseJson` callsite. - `parseJson(adapter, raw, message)` — generic JSON-via-Schema decode for non-tool payloads. - `chunkError(adapter, message, ...)` — typed `ProviderChunkError` constructor for stream-time failures. +- `validateWith(decoder)` — lifts a Schema decode effect into the protocol's `validate` shape, mapping parse errors to `InvalidRequestError`. +- `codecs({ adapter, draft, target, chunk, chunkErrorMessage })` — the encode/decode bundle each protocol needs (request body encode, draft → target validate, chunk decode). -If you find yourself copying a 3-to-5-line snippet between two adapters, lift it into `ProviderShared` next to these helpers rather than duplicating. +If you find yourself copying a 3-to-5-line snippet between two protocols, lift it into `ProviderShared` next to these helpers rather than duplicating. ### Patches From 9928917899fe69d4f49cde1ec1b4338fc29dfaf3 Mon Sep 17 00:00:00 2001 From: Kit Langton Date: Tue, 28 Apr 2026 17:12:13 -0400 Subject: [PATCH 076/196] simplify(llm): remove dead ProviderShared.sse and withQuery helpers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After migration to Adapter.fromProtocol, the sse() convenience wrapper and withQuery() URL builder are no longer called anywhere — Framing.sse and Endpoint.baseURL handle their responsibilities directly.

Setting provider scopes the adapter in the registry so requests must use the same provider id, which broke session/llm-native tests that build models with provider 'amazon-bedrock' against the bedrock-converse adapter. Adapters should stay protocol-only by default and only set provider when the deployment is genuinely scoped (e.g. an Azure-only adapter that does not work for native OpenAI).

Why This Design | You are relating this to AI SDK or OpenCode's current provider stack. | + +## 1. The API You Use + +Most code should live here. + +```ts +import { Effect, Layer } from "effect" +import { LLM, RequestExecutor } from "@opencode-ai/llm" +import { OpenAI } from "@opencode-ai/llm/providers" + +const model = OpenAI.model("gpt-4o-mini", { + apiKey: Bun.env.OPENAI_API_KEY, +}) + +const program = Effect.gen(function* () { + const response = yield* LLM.generate({ + model, + prompt: "Say hello.", + }) + + console.log(response.text) +}).pipe(Effect.provide(Layer.mergeAll(LLM.layer({ providers: [OpenAI] }), RequestExecutor.defaultLayer))) +``` + +The public rule is: + +```txt +provider helper -> model reference -> LLM.generate / LLM.stream +``` + +Provider helpers should feel boring at use sites. + +```ts +OpenAI.model("gpt-4o-mini", { apiKey }) +Anthropic.model("claude-3-5-sonnet-latest", { apiKey }) +Google.model("gemini-2.0-flash", { apiKey }) +OpenRouter.model("openai/gpt-4o-mini", { apiKey }) +OpenAICompatible.model("gpt-4o-mini", { + name: "local-gateway", + baseURL: "http://localhost:11434/v1", +}) +``` + +For OpenAI, `OpenAI.model(...)` means Responses. Use `OpenAI.chat(...)` only when you specifically need Chat Completions. + +
+What this section hides + +The call site does not name adapters, protocols, endpoints, auth, framing, patches, target payloads, or stream parsers. + +Those are runtime concerns. They should be inspectable and composable, but not required for normal use. + +
+ +## 2. What A Model Reference Means + +A model reference is a route card. It says which model to call, which provider owns the deployment, and which wire protocol can talk to it. + +```ts +OpenAI.model("gpt-4o-mini", { apiKey }) + -> provider: openai + -> protocol: openai-responses + -> id: gpt-4o-mini + +OpenRouter.model("openai/gpt-4o-mini", { apiKey }) + -> provider: openrouter + -> protocol: openai-compatible-chat + -> id: openai/gpt-4o-mini + +OpenAICompatible.model("gpt-4o-mini", { name: "local-gateway", baseURL }) + -> provider: local-gateway + -> protocol: openai-compatible-chat + -> id: gpt-4o-mini +``` + +This split is the core design choice. + +| Concept | Question it answers | +| -------------------------------------------- | ------------------------------------------------------------ | +| `provider` | Who is the deployment or product surface? | +| `protocol` | Which request/response shape should the runtime use? | +| `id` | Which model/deployment id should be sent? | +| `baseURL` | Where should HTTP go? | +| `apiKey`, `headers`, `queryParams`, `native` | What deployment-specific transport data is needed? | +| `capabilities`, `limits` | What normalized features and constraints should callers see? | + +Provider identity and wire protocol often differ. OpenRouter is not OpenAI, but many OpenRouter models speak enough OpenAI Chat shape to reuse the OpenAI Chat protocol. + +
+Conceptual ModelRef shape + +```ts +type ModelRef = { + id: ModelID + provider: ProviderID + protocol: ProtocolID + baseURL?: string + apiKey?: string + headers?: Record + queryParams?: Record + capabilities: ModelCapabilities + limits: ModelLimits + native?: Record +} +``` + +`ModelRef` is not a provider client. It does not send requests. It is the stable, serializable description of what should be called. + +
+ +## 3. What Happens At Runtime + +At runtime, every request follows the same path. + +```txt +LLM.generate({ model, prompt }) + -> LLM.request(...) + -> LLMClient + -> adapter selected by model.protocol + -> provider-native target payload + -> HttpClientRequest + -> RequestExecutor + -> provider response stream + -> LLMEvent stream + -> LLMResponse +``` + +The high-level API hides that pipeline. + +```ts +const response = + yield * + LLM.generate({ + model: OpenAI.model("gpt-4o-mini", { apiKey }), + prompt: "Say hello.", + }) +``` + +The lower-level runtime sees this shape. + +```ts +const request = LLM.request({ + model, + prompt: "Say hello.", +}) + +const client = LLMClient.make({ + adapters: [OpenAIResponses.adapter, OpenAIChat.adapter], + patches: ProviderPatch.defaults, +}) + +const response = yield * client.generate(request) +``` + +
+Adapter pipeline + +The adapter is selected by `request.model.protocol`. + +```ts +const adapter = adapters.get(request.model.protocol) +const draft = adapter.prepare(request) +const patched = applyTargetPatches(draft) +const target = adapter.validate(patched) +const http = adapter.toHttp(target) +const response = yield * RequestExecutor.execute(http) +const events = adapter.parse(response) +``` + +`generate` collects the same `LLMEvent` stream that `stream` exposes incrementally. + +
+ +## 4. How Providers Are Built + +Provider behavior is split across reusable layers instead of one large provider class. + +```txt +Provider helper + creates ModelRef values + +Provider module + exports adapters and helper constructors + +Adapter + composes Protocol + Endpoint + Auth + Framing + +Protocol + owns provider-native request and stream semantics +``` + +The composition rule is: + +```txt +Adapter = Protocol + Endpoint + Auth + Framing +``` + +OpenAI Chat is a normal adapter composition. + +```ts +export const adapter = Adapter.make({ + id: "openai-chat", + protocol: OpenAIChat.protocol, + endpoint: Endpoint.baseURL({ + default: "https://api.openai.com/v1", + path: "/chat/completions", + }), + auth: Auth.openAI, + framing: Framing.sse, +}) +``` + +OpenAI-compatible Chat is the same protocol with different deployment axes. + +```txt +OpenAI-compatible Chat adapter + = OpenAIChat.protocol + + required baseURL endpoint + + bearer auth + + SSE framing +``` + +That is why these can share implementation without pretending they are the same provider. + +```ts +OpenAI.chat("gpt-4o-mini", { apiKey }) +OpenRouter.model("openai/gpt-4o-mini", { apiKey }) +OpenAICompatible.model("gpt-4o-mini", { name: "local-gateway", baseURL }) +``` + +

That lifecycle is the module earning its keep, but it does not have its own seam. + +## Proposed Shape + +Introduce a patch pipeline module that closes over the client patch set once: + +```ts +const pipeline = PatchPipeline.make(options.patches) +``` + +`PatchPipeline.make(...)` accepts the same patch inputs `LLMClient` accepts today: + +```ts +PatchPipeline.make(options.patches) +PatchPipeline.make(ProviderPatch.defaults) +PatchPipeline.make(Patch.registry([...])) +``` + +The pipeline instance is immutable and reused for each request handled by that `LLMClient`. + +```ts +export interface PatchPipeline { + readonly patchRequest: (request: LLMRequest) => Effect.Effect + readonly patchTarget: (input: PatchTargetInput) => Effect.Effect, LLMError> + readonly patchStreamEvents: (input: PatchStreamInput) => Stream.Stream +} +``` + +The names should stay patch-focused. Avoid `prepareRequest` and `prepareTarget` because `LLMClient.prepare`, `Adapter.prepare`, and Protocol lowering already use prepare terminology. + +One possible state shape: + +```ts +export interface PatchedRequest { + readonly original: LLMRequest + readonly request: LLMRequest + readonly trace: ReadonlyArray +} + +export interface PatchTargetInput { + readonly state: PatchedRequest + readonly target: Target + readonly adapterPatches: ReadonlyArray> + readonly validateTarget: (target: Target) => Effect.Effect +} + +export interface PatchedTarget { + readonly request: LLMRequest + readonly target: Target + readonly trace: ReadonlyArray +} +``` + +Then `LLMClient.compile(...)` becomes routing plus Adapter orchestration: + +```ts +const pipeline = PatchPipeline.make(options.patches) + +const compile = Effect.fn("LLM.compile")(function* (request: LLMRequest) { + const adapter = adapters.get(request.model.protocol) ?? modelAdapters.get(request.model) + if (!adapter) return yield* noAdapter(request.model) + + const patchedRequest = yield* pipeline.patchRequest(request) + const candidate = yield* adapter.prepare(patchedRequest.request) + const patchedTarget = yield* pipeline.patchTarget({ + state: patchedRequest, + target: candidate, + adapterPatches: adapter.patches, + validateTarget: adapter.validate, + }) + + const http = yield* adapter.toHttp(patchedTarget.target, { + request: patchedTarget.request, + patchTrace: patchedTarget.trace, + }) + + return { + request: patchedTarget.request, + adapter, + target: patchedTarget.target, + http, + patchTrace: patchedTarget.trace, + } +}) +``` + +Stream patching also moves behind the same module, but only after Adapter parsing: + +```ts +const events = compiled.adapter.parse(response, { + request: compiled.request, + patchTrace: compiled.patchTrace, +}) + +return pipeline.patchStreamEvents({ + request: compiled.request, + events, +}) +``` + +This is the important cleanup: `LLMClient` no longer hand-assembles phase plans, context refresh, route protection, target patch ordering, validation timing, stream patch mapping, or patch trace concatenation. + +## Performance And Simplicity + +This design should be at least as performant as the current shape, and likely a little better, because patches generally live at client construction time rather than changing per request. + +Today, every request rebuilds phase plans: + +```ts +plan({ phase: "request", context, patches: registry.request }) +plan({ phase: "prompt", context, patches: registry.prompt }) +plan({ phase: "tool-schema", context, patches: registry.toolSchema }) +plan({ phase: "target", context, patches: [...adapter.patches, ...registry.target] }) +``` + +Each plan filters and sorts its phase patches. That cost is tiny compared with an LLM request, but it is still repeated work and repeated code. + +The patch pipeline can precompile the client-level patch set once: + +```ts +const pipeline = PatchPipeline.make(options.patches) +``` + +At construction time, the pipeline can: + +- Normalize `undefined`, a patch array, or a `PatchRegistry` into one internal shape. +- Group patches by phase. +- Sort each client-level phase by `order` and `id` once. +- Store empty-phase fast paths so requests with no patches avoid allocation-heavy plan construction. + +Per request, the pipeline still must evaluate `when(context)` predicates because predicates depend on the current request, model, protocol, metadata, tools, and provider. That part cannot be safely precompiled away unless a future patch type declares itself unconditional. + +Target patches are slightly different because adapter-local target patches vary by selected Adapter. Keep the first version simple: + +```ts +pipeline.patchTarget({ + state, + target, + adapterPatches: adapter.patches, + validateTarget: adapter.validate, +}) +``` + +The pipeline can combine already-sorted client target patches with adapter patches and apply the same ordering rule. If target patch counts ever become large, the pipeline can cache the sorted merged target patch list in a `WeakMap` keyed by the Adapter or by the adapter patch array. That is an internal Implementation optimization; the Interface does not need to expose it. + +The important simplicity win is bigger than the micro-performance win. `LLMClient` would stop describing the patch algorithm in five places. The pipeline becomes a reusable compiled patch lifecycle: one small Interface, one place to optimize, one place to test. + +## What The Module Owns + +The patch pipeline module should own: + +- Normalizing `PatchRegistry | ReadonlyArray | undefined` into a registry. +- Building fresh `PatchContext` after each request-shaped phase. +- Running request patches before prompt patches. +- Enforcing that request-shaped patches do not change `model.provider`, `model.id`, or `model.protocol`. +- Running tool-schema patches against every tool definition only when tools exist and patches matched. +- Emitting tool-schema trace once per matched patch, not once per tool. +- Combining request, prompt, tool-schema, and target traces in lifecycle order. +- Combining adapter-local target patches with client registry target patches and applying the shared patch ordering rule. +- Invoking Adapter target validation after target patches. +- Applying stream patches to parsed `LLMEvent` streams with the compiled request context. + +It should not own: + +- Adapter lookup. +- Protocol lowering via `adapter.prepare(...)`. +- Target validation Implementation. +- HTTP request construction. +- Provider-specific patch definitions. +- Provider stream parsing. + +Those remain behind the Adapter, Protocol, Endpoint, Auth, Framing, ProviderPatch, and RequestExecutor modules. + +## How This Cleans Up Code Elsewhere + +`src/adapter.ts` gets smaller and more navigable: + +- `normalizeRegistry(...)` moves out. +- `ensureSameRoute(...)` moves out. +- `compile(...)` stops constructing four separate plans. +- `compile(...)` stops manually refreshing contexts. +- `compile(...)` stops manually deciding when tool-schema traces count. +- `compile(...)` stops manually concatenating patch traces. +- `stream(...)` stops manually planning stream patches. + +`src/patch.ts` becomes clearer: + +- Patch constructors and predicates remain the primitive Interface. +- `plan(...)` can stay as an internal or low-level single-phase helper. +- Lifecycle semantics move to `src/patch-pipeline.ts` instead of being implied by Adapter tests. + +Provider patch modules stay focused: + +- `ProviderPatch.defaults` remains a list of provider facts. +- Provider-specific patches do not need to know lifecycle ordering. +- Adapter-local target patches keep living on the selected Adapter. + +Tests get better locality: + +- Patch primitive tests stay in `patch.test.ts`. +- Patch lifecycle tests move to `patch-pipeline.test.ts`. +- Adapter tests keep only Adapter responsibilities and one end-to-end smoke test that `LLMClient` invokes the pipeline. + +## Why This Is Deepening + +The patch pipeline would be a deeper module because a small Interface hides a larger amount of behaviour. + +Current Interface: + +```ts +plan({ phase, context, patches }).apply(value) +``` + +That Interface is shallow because the caller must know the lifecycle. + +Proposed Interface: + +```ts +const pipeline = PatchPipeline.make(options.patches) +const request = yield* pipeline.patchRequest(input) +const target = yield* pipeline.patchTarget({ state: request, target, adapterPatches, validateTarget }) +const events = pipeline.patchStreamEvents({ request: target.request, events }) +``` + +That Interface is deeper because callers get ordering, context refresh, route protection, tool-schema handling, target patch composition, validation timing, stream mapping, and trace assembly without knowing each step. + +## Principles + +### Module + +Today, the real patch lifecycle is an unnamed module embedded in `LLMClient.compile(...)`. Naming it as a patch pipeline module gives it one Interface and one Implementation. + +### Interface + +The Interface becomes the test surface. Tests should ask what the pipeline guarantees: request patches run before prompt patches, contexts refresh, route changes fail, target patches trace after tool-schema patches, validation runs after target patches, and stream patches see the compiled request. + +### Depth + +The module becomes deep because callers learn a small lifecycle Interface instead of the full phase choreography. More behaviour sits behind less required knowledge. + +### Seam + +The seam moves from scattered calls to `plan(...)` into the patch pipeline Interface. The existing patch Interface remains the seam where provider-specific patch behaviour enters the lifecycle. + +### Adapter + +Provider-specific patches are Adapters at the patch seam: each concrete patch satisfies the patch Interface. Adapter-local target patches remain local to the selected Adapter, but the pipeline owns how those patches combine with client registry target patches. + +### Leverage + +Callers get more leverage because `LLMClient`, tests, and future request-compilation paths can reuse one lifecycle. A fix to context refresh or route protection pays back everywhere. + +### Locality + +Maintainers get more locality because patch bugs concentrate in the patch pipeline Implementation. Provider patches can stay focused on provider facts instead of lifecycle rules. + +### Deletion Test + +Deleting the current `plan(...)` helper removes only a small filter/sort/reduce. Deleting the proposed patch pipeline would make lifecycle complexity reappear in `LLMClient`, tests, and any future compilation path. That means the proposed module earns its keep. + +### One Adapter = Hypothetical Seam, Two Adapters = Real Seam + +This proposal does not add a speculative seam with fake alternative implementations. It deepens an existing real seam: many provider patches already satisfy the patch Interface, and adapter-local plus client registry target patches already vary across providers and call sites. The missing piece is locality for the lifecycle that applies those Adapters. + +## Benefits + +Locality improves because lifecycle rules live in one module instead of being embedded in request compilation. + +Leverage improves because every provider patch and every client path gets the same ordering, trace, validation timing, and route-invariant behaviour. + +Tests improve because the patch pipeline Interface becomes the test surface. Instead of constructing fake protocols, fake adapters, fake framing, and scripted HTTP flows to verify patch lifecycle behaviour, tests can exercise the lifecycle directly. + +Useful tests: + +- Adapter selection happens before request patches. +- Request patches run before prompt patches. +- Prompt patch predicates see the request after request patches. +- Request-shaped patches cannot change `model.provider`, `model.id`, or `model.protocol`. +- Tool-schema patches are skipped when there are no tools. +- Tool-schema traces appear only when tool-schema patches ran. +- Tool-schema trace appears once per matched patch, not once per tool. +- Adapter target patches and client registry target patches follow the shared patch ordering rule. +- Target validation runs after target patches. +- Stream patches see the compiled request, not the original request. +- Pipeline construction accepts `undefined`, a patch array, or a `PatchRegistry`. + +## What Not To Do Yet + +Do not change the public patch definition shape unless the pipeline proves it needs a missing field. + +Do not create a full plugin system for patch ordering. + +Do not move provider-specific patch logic into the pipeline. + +Do not make target patch typing more ambitious in this step; target patches are already typed at adapter construction sites and erased in the registry. + +Do not move Adapter lookup, Protocol lowering, HTTP construction, or stream parsing into the pipeline. + +Do not change provider behaviour while extracting the lifecycle. + +## Migration Plan + +1. Add `src/patch-pipeline.ts` with the lifecycle Implementation and focused tests. +2. Keep `Patch.plan(...)` public during migration and use it internally inside the pipeline. +3. Move `normalizeRegistry(...)` and `ensureSameRoute(...)` from `src/adapter.ts` into the pipeline module. +4. Add `patchRequest(...)` that runs request, prompt, and tool-schema phases and returns a carried request state. +5. Add `patchTarget(...)` that applies adapter-local target patches, client registry target patches, Adapter validation, and returns a carried target state with combined trace. +6. Add `patchStreamEvents(...)` that applies stream patches to parsed `LLMEvent` streams. +7. Add `test/patch-pipeline.test.ts` with lifecycle tests before changing `LLMClient`. +8. Replace handwritten phase choreography in `LLMClient.compile(...)` and `LLMClient.stream(...)` with the pipeline. +9. Keep one adapter-level smoke test proving `LLMClient` invokes patches end-to-end. +10. Move or delete adapter-level lifecycle tests that are now covered by patch pipeline tests. +11. Decide later whether `Patch.plan(...)` remains public or becomes internal. + +## Open Questions + +Should `Patch.plan(...)` remain public as a low-level primitive, or should the patch pipeline become the only exported lifecycle Interface? + +Should stream patches be part of the same pipeline module from the first extraction, or should the first extraction focus only on request-to-target compilation? + +Should the pipeline return one combined trace array, or should it preserve phase-grouped traces internally for better debugging while exposing one ordered trace to callers? + +Should route protection apply only after request and prompt phases, or should the pipeline also assert that target and stream phases cannot observe changed route state? + +Should target patch ordering keep the current global `order`/`id` rule across adapter-local and client registry patches, or should adapter-local target patches get an explicit ordering band before client registry target patches? + +## Recommendation + +Do this before adding more provider-specific patches. The current shape is already correct enough to extract safely, and the next set of provider quirks will make patch ordering and conversation-shape rules more important. A patch pipeline module would turn implicit lifecycle knowledge into a deep Interface with better locality, better leverage, and a clearer test surface. diff --git a/packages/llm/PROPOSAL.provider-profiles.md b/packages/llm/PROPOSAL.provider-profiles.md deleted file mode 100644 index 59b767d09cbb..000000000000 --- a/packages/llm/PROPOSAL.provider-profiles.md +++ /dev/null @@ -1,223 +0,0 @@ -# Proposal: Provider Profiles - -## Summary - -OpenAI-compatible provider knowledge is currently split across provider data, model helpers, resolver wiring, public provider wrappers, and tests.

To make OpenCode load those from config the same way it loads AI SDK packages, we would add an explicit native-provider loader/registry analogous to the AI SDK `model.api.npm` loader. diff --git a/packages/llm/PROPOSAL.openai-compatible-wrappers.md b/packages/llm/PROPOSAL.openai-compatible-wrappers.md index dd5c610e82d3..124b3ddaf107 100644 --- a/packages/llm/PROPOSAL.openai-compatible-wrappers.md +++ b/packages/llm/PROPOSAL.openai-compatible-wrappers.md @@ -6,7 +6,7 @@ Keep `OpenAICompatibleChat` as the shared implementation for providers that expo | Level | Use When | Example | | --- | --- | --- | -| Profile | Provider only needs `provider`, `baseURL`, capabilities, and resolver defaults. | DeepSeek text/tool basics, TogetherAI, Cerebras, Fireworks. | +| Profile | Provider only needs `provider`, `baseURL`, and capabilities. | DeepSeek text/tool basics, TogetherAI, Cerebras, Fireworks. | | Thin wrapper | Provider speaks OpenAI Chat shape but needs named options, patches, capability defaults, metadata extraction, or provider-defined tools. | Mistral, Groq, Perplexity. | | Dedicated protocol | Request lowering or stream parsing stops being OpenAI Chat-compatible. | Not justified for these providers yet. | @@ -71,10 +71,12 @@ const llm = LLMClient.make({ adapters: OpenAICompatible.adapters }) Current OpenCode bridge shape: ```ts -const resolved = OpenAICompatibleProfiles.resolve("deepseek") -// provider: "deepseek" -// protocol: "openai-compatible-chat" -// baseURL: "https://api.deepseek.com/v1" +OpenAICompatible.model("deepseek-chat", { + provider: "deepseek", + baseURL: OpenAICompatibleProfiles.profiles.deepseek.baseURL, + apiKey, +}) +// provider: "deepseek", protocol: "openai-compatible-chat" ``` Current default patches already contain provider-specific OpenAI-compatible policy: @@ -105,7 +107,7 @@ The lesson is not “copy AI SDK and create full dedicated adapters.” The less ## Proposed Shape -A thin wrapper is a provider-local module that reuses the common OpenAI-compatible adapter and protocol, then exports provider-specific model helpers, resolver, and patches. +A thin wrapper is a provider-local module that reuses the common OpenAI-compatible adapter and protocol, then exports provider-specific model helpers, adapters, and patches.

are worth showing off. + +The short version: the public API is small, providers are built from composable pieces, stream parsing normalizes very different APIs into one event model, and tests can run against deterministic fixtures or replayed live HTTP cassettes. + +Use this as a code-reading path. Open the linked files in order and skim the referenced sections. + +## 1. Start With The Use Site + +Start with the runnable tutorial: [`example/tutorial.ts`](./example/tutorial.ts). + +It shows the package from the caller's point of view: + +- Pick a provider model. +- Build a provider-neutral request. +- Collect a response with `LLM.generate`. +- Stream normalized `LLMEvent`s with `LLM.stream`. +- Define typed tools with Effect Schema. +- Build a fake provider from protocol pieces. + +The public shape is intentionally boring: + +```ts +const model = OpenAI.model("gpt-4o-mini", { apiKey }) +const response = yield * LLM.generate({ model, prompt: "Say hello." }) +``` + +The interesting part is that the boring use site can route through OpenAI Responses, OpenAI Chat, Anthropic Messages, Gemini, Bedrock Converse, OpenRouter, Azure, or an arbitrary OpenAI-compatible server without changing the caller's mental model. + +## 2. The Public Runtime Is Small + +The public `LLM` namespace lives in [`src/llm.ts`](./src/llm.ts). + +Read these pieces first: + +- `LLM.make` builds a runtime from providers, adapters, and patches. +- `LLM.layer` provides that runtime as an Effect service. +- `LLM.generate` and `LLM.stream` are thin service calls. +- `LLM.request` turns ergonomic input into canonical schema classes. +- `LLM.streamWithTools` delegates to `ToolRuntime`. + +The canonical data model is in [`src/schema.ts`](./src/schema.ts). That file defines the runtime shapes that every provider lowers from or emits back to: `ModelRef`, `LLMRequest`, `Message`, `ContentPart`, `LLMEvent`, `Usage`, and the typed error classes. + +The key design choice is that the public request model is provider-neutral. Provider-specific wire bodies are not represented in `LLMRequest`; they live in protocol-local payload schemas. + +## 3. Name The Big Pieces + +Before following one request through the runtime, name the main concepts: + +- `LLMRequest`: the canonical provider-neutral request. This is what callers build and what patches/protocols read. +- `ModelRef`: the selected model plus routing metadata. `model.adapter` chooses the runnable adapter route; `model.protocol` records the wire protocol semantics. +- `Protocol`: the wire-format brain. It converts `LLMRequest` into a provider-native payload and parses provider-native stream chunks back into `LLMEvent`s. +- `Adapter`: the runnable deployment. It combines one `Protocol` with an `Endpoint`, `Auth`, `Framing`, headers, and adapter-local payload patches. +- `PatchPipeline`: the tweak layer. It can rewrite the canonical request before lowering, rewrite tool schemas, rewrite the provider payload after lowering, or rewrite normalized stream events. +- `RequestExecutor`: the transport boundary. It sends an `HttpClientRequest` and returns an `HttpClientResponse`. +- `LLMEvent`: the normalized stream output. Every provider eventually emits the same event vocabulary. + +The most important distinction is adapter route versus protocol implementation: + +```ts +const model: ModelRef = OpenAICompatible.deepseek.model("deepseek-chat") + +model.adapter // "openai-compatible-chat" — which runnable adapter to use +model.protocol // "openai-chat" — which wire protocol it speaks +``` + +Most adapters have the same value for both fields. OpenAI-compatible Chat is the useful exception: it routes through the generic compatible adapter while reusing the OpenAI Chat wire protocol. + +## 4. Follow One Request Through The Pipeline + +The runtime pipeline is concentrated in [`src/adapter.ts`](./src/adapter.ts). + +The important functions are: + +- `Adapter.model`, which binds a user-facing model helper to the adapter that can run it. +- `LLMClient.make`, which selects an adapter, applies patches, builds the payload, sends HTTP, and parses the response. +- `Adapter.make`, which composes protocol semantics with endpoint, auth, and framing. + +At runtime, the flow is easier to read as a sequence of value transformations: + +The snippet below is pseudo-code. It shows resolved values at each boundary, not the `Effect` wrappers used by the implementation. + +```ts +type Payload = OpenAIChatPayload +type Frame = string +type Chunk = OpenAIChatChunk +type State = OpenAIChatStreamState + +// ----------------------------------------------------------------------------- +// Stage 1: Caller Forms A Canonical Request +// ----------------------------------------------------------------------------- + +// Use-site input can be ergonomic `RequestInput`... +const input: RequestInput = { + model: OpenAI.model("gpt-4o-mini", { apiKey }), + system: "You are concise.", + prompt: "Say hello.", +} + +// RequestInput -> LLMRequest +// This canonicalizes the ergonomic caller shape into the common runtime schema. +const request: LLMRequest = LLM.request(input) + +// ----------------------------------------------------------------------------- +// Stage 2: Caller Hands The Request To The Client +// ----------------------------------------------------------------------------- + +// The caller hands that request to the client.

That makes request-shape tests cheap and makes demos easy because you can show exactly what would be sent. It is intentionally not part of the top-level `LLM` convenience API. + +See examples in [`test/provider/openai-chat.test.ts`](./test/provider/openai-chat.test.ts) and [`test/provider/openai-responses.test.ts`](./test/provider/openai-responses.test.ts). + +## 5. Protocols Are The Provider-Native Semantics + +The protocol abstraction is defined in [`src/protocol.ts`](./src/protocol.ts). + +A protocol owns the parts that are intrinsic to an API family: + +- `payload`: Effect Schema for the provider-native JSON request body. +- `toPayload`: convert common `LLMRequest` into that provider payload. +- `chunk`: Effect Schema for one framed response item. +- `initial`: initial parser state for a response stream. +- `process`: chunk-by-chunk state machine that emits common `LLMEvent`s. +- `onHalt`: optional final flush when the stream ends. + +The type shape is deliberately four-part: request payload, framed response item, decoded chunk, and parser state. + +```ts +interface Protocol { + readonly id: ProtocolID + readonly payload: Schema.Codec + readonly toPayload: (request: LLMRequest) => Effect.Effect + readonly chunk: Schema.Codec + readonly initial: () => State + readonly process: ( + state: State, + chunk: Chunk, + ) => Effect.Effect], ProviderChunkError> + readonly onHalt?: (state: State) => ReadonlyArray +} +``` + +Read those generics as the parser pipeline: + +- `Payload`: the provider-native JSON body after request conversion and payload patches. +- `Frame`: one response unit after byte framing, such as an SSE `data:` string or a Bedrock event-stream object. +- `Chunk`: the provider-native stream chunk after Schema decoding one frame. +- `State`: the accumulator needed to turn a sequence of chunks into common events. + +The main protocol implementations are: + +- OpenAI Chat Completions: [`src/protocols/openai-chat.ts`](./src/protocols/openai-chat.ts) +- OpenAI Responses: [`src/protocols/openai-responses.ts`](./src/protocols/openai-responses.ts) +- Anthropic Messages: [`src/protocols/anthropic-messages.ts`](./src/protocols/anthropic-messages.ts) +- Gemini GenerateContent: [`src/protocols/gemini.ts`](./src/protocols/gemini.ts) +- Bedrock Converse: [`src/protocols/bedrock-converse.ts`](./src/protocols/bedrock-converse.ts) + +The protocol files are intentionally sectioned the same way: + +```ts +Public Model Input +Request Payload Schema +Request To Payload +Stream Parsing +Protocol And Adapter +Model Helper +``` + +That layout makes each protocol readable as a story: what does the wire payload look like, how do common requests turn into it, how do provider stream chunks become common events, and how is the runnable adapter assembled? + +## 6. Adapter Composition Is Where The Reuse Shows Up + +The adapter composition rule is: + +```ts +Adapter = Protocol + Endpoint + Auth + Framing +``` + +The pieces live in these files: + +- Protocol contract: [`src/protocol.ts`](./src/protocol.ts) +- Adapter constructor: [`src/adapter.ts`](./src/adapter.ts) +- Endpoint rendering: [`src/endpoint.ts`](./src/endpoint.ts) +- Auth strategies: [`src/auth.ts`](./src/auth.ts) +- Stream framing: [`src/framing.ts`](./src/framing.ts) + +The runnable adapter erases the response internals after composition. Callers only need a payload type plus a normalized parser: + +```ts +interface Adapter { + readonly id: string + readonly protocol: ProtocolID + readonly payloadSchema: Schema.Codec + readonly patches: ReadonlyArray> + readonly toPayload: (request: LLMRequest) => Effect.Effect + readonly toHttp: ( + payload: Payload, + context: HttpContext, + ) => Effect.Effect + readonly parse: ( + response: HttpClientResponse.HttpClientResponse, + context: HttpContext, + ) => Stream.Stream +} +``` + +`id` is the adapter route used for model lookup. `protocol` is the wire protocol implementation id. Most adapters use matching values, but OpenAI-compatible Chat is intentionally different: the adapter route is `openai-compatible-chat`, while the reused wire protocol is `openai-chat`. + +`Endpoint` receives both the canonical request and the validated provider payload, so dynamic paths can read either side: + +```ts +interface EndpointInput { + readonly request: LLMRequest + readonly payload: Payload +} + +type EndpointPart = string | ((input: EndpointInput) => string) + +interface Endpoint { + readonly baseURL?: EndpointPart + readonly path: EndpointPart + readonly required?: string +} +``` + +`Auth` is a per-request header function. It can be a simple API-key merge or a full body-signing strategy: + +```ts +type Auth = (input: AuthInput) => Effect.Effect, LLMError> + +interface AuthInput { + readonly request: LLMRequest + readonly method: "POST" | "GET" + readonly url: string + readonly body: string + readonly headers: Record +} +``` + +`Framing` is the transport-to-protocol seam. It does not know about JSON payload schemas or common events: + +```ts +interface Framing { + readonly id: string + readonly frame: (bytes: Stream.Stream) => Stream.Stream +} +``` + +OpenAI Chat is the base case. It defines a full protocol and adapter in [`src/protocols/openai-chat.ts`](./src/protocols/openai-chat.ts). + +OpenAI-compatible Chat is the code-reuse showcase in [`src/protocols/openai-compatible-chat.ts`](./src/protocols/openai-compatible-chat.ts): + +```ts +export const adapter = Adapter.make({ + id: "openai-compatible-chat", + protocol: OpenAIChat.protocol, + endpoint: Endpoint.baseURL({ + path: "/chat/completions", + required: "OpenAI-compatible Chat requires a baseURL", + }), + framing: Framing.sse, +}) +``` + +That adapter reuses `OpenAIChat.protocol` end-to-end. It changes the deployment axes: adapter route id, endpoint, and provider identity. + +The payoff is that providers like DeepSeek, TogetherAI, Cerebras, Baseten, Fireworks, DeepInfra, Groq, xAI, and OpenRouter can share the same Chat protocol instead of copying a 300-line adapter. + +Provider family wiring lives here: + +- Generic OpenAI-compatible provider helper: [`src/providers/openai-compatible.ts`](./src/providers/openai-compatible.ts) +- Provider profiles and capabilities: [`src/providers/openai-compatible-profile.ts`](./src/providers/openai-compatible-profile.ts) +- OpenRouter wrapper with provider-specific options: [`src/providers/openrouter.ts`](./src/providers/openrouter.ts) + +## 7. Provider Helpers Keep Call Sites Boring + +The provider modules exported from [`src/providers.ts`](./src/providers.ts) are thin use-site APIs. + +Examples: + +- `OpenAI.model` defaults to Responses, and `OpenAI.chat` constructs a Chat model in [`src/providers/openai.ts`](./src/providers/openai.ts). +- `Anthropic.model` constructs a Messages model in [`src/providers/anthropic.ts`](./src/providers/anthropic.ts). +- `Google.model` constructs a Gemini model in [`src/providers/google.ts`](./src/providers/google.ts). +- `AmazonBedrock.model` constructs a Bedrock Converse model with credentials in [`src/providers/amazon-bedrock.ts`](./src/providers/amazon-bedrock.ts). +- `OpenAICompatible.deepseek.model` constructs a named OpenAI-compatible deployment model in [`src/providers/openai-compatible.ts`](./src/providers/openai-compatible.ts). +- `OpenRouter.model` constructs an OpenAI-compatible Chat model with OpenRouter options in [`src/providers/openrouter.ts`](./src/providers/openrouter.ts). + +Provider helpers should usually not contain stream parsing, JSON decoding, or protocol details. They set provider identity, defaults, capabilities, deployment options, and adapter registrations. + +## 8. Patches Keep Provider Quirks Out Of Common Schemas + +The patch system keeps one-off provider/model quirks from leaking into `LLMRequest`. + +This is not a substitute for putting the right behavior in a protocol. If Anthropic Messages always lowers a common feature the same way, that belongs in `anthropic-messages.ts`. A patch is for behavior that is conditional on provider, model, deployment, or caller policy: the same protocol shape is mostly right, but one route needs a small, inspectable rewrite. + +That is why the pipeline exists. OpenCode already had a provider-transform layer because real providers reject or require little differences that are not worth baking into the common request model. The package keeps that idea, but makes each tweak named, phase-scoped, typed, ordered, and predicate-gated. + +Start here: + +- Patch types and constructors: [`src/patch.ts`](./src/patch.ts) +- Patch execution pipeline: [`src/patch-pipeline.ts`](./src/patch-pipeline.ts) +- Default provider patch registry: [`src/provider-patch.ts`](./src/provider-patch.ts) +- Provider-local patch example, OpenAI Chat include usage: [`src/protocols/openai-chat.ts`](./src/protocols/openai-chat.ts) +- Provider-specific wrapper patch, OpenRouter options: [`src/providers/openrouter.ts`](./src/providers/openrouter.ts) + +The pipeline has five phases: + +```ts +type PatchPhase = "request" | "prompt" | "tool-schema" | "payload" | "stream" +``` + +The phases used today are: + +- `prompt`: rewrite message history before protocol lowering. +- `tool-schema`: rewrite tool JSON Schema before protocol lowering. +- `payload`: rewrite the provider-native payload after lowering and before HTTP encoding. + +The phases available but not heavily used today are: + +- `request`: reserved for whole-request policy before prompt/tool-schema patches. +- `stream`: reserved for normalized event rewrites after provider parsing. + +There are two patch sources because they solve different problems: + +- Adapter-local patches belong to one adapter's wire format. They are payload-only today, because the adapter owns `Payload`. Use them for things like `includeUsage` or OpenRouter payload options. +- Runtime/default patches are cross-adapter policy. They can run before lowering, so they can clean the canonical request, prompt history, or tool schemas before any protocol turns them into provider-native JSON. + +If every tweak lived on adapters, cross-cutting behavior would either be duplicated across many adapters or hidden inside protocols where callers cannot turn it off. If every tweak were global, adapter-owned wire details would become too detached from the adapter that understands the payload. The split keeps protocol semantics stable, adapter quirks close to adapters, and runtime policy configurable at `LLM.make(...)` / `LLMClient.make(...)`. + +Default patches are enabled by `LLM.make(...)` through `ProviderPatch.defaults`. Direct `LLMClient.make(...)` callers opt in by passing `patches`, or by using adapters that include adapter-local payload patches. + +Today the default provider patches do concrete work: + +- Anthropic and Bedrock: remove empty text/reasoning content that those APIs reject. +- Claude: scrub tool call IDs to Claude's accepted character set. +- Mistral/Devstral: shorten and scrub tool call IDs, and repair tool-result/user-message ordering. +- Anthropic/Claude: split malformed assistant turns so `tool_use` blocks are not followed by non-tool content. +- DeepSeek/OpenAI-compatible reasoning models: move common reasoning content into provider-native replay fields. +- Unsupported media: turn unsupported user attachments into model-visible error text instead of sending a provider-invalid request. +- Moonshot/Kimi: sanitize tool JSON Schema shapes the provider rejects. +- Prompt caching: mark cache-capable providers' first system parts and last message text blocks with ephemeral cache hints. + +Adapter-local payload patches are used where the quirk is specific to one adapter deployment: + +- OpenAI Chat and OpenAI-compatible Chat: `includeUsage` adds `stream_options.include_usage` so streaming responses include the final usage chunk. +- OpenRouter: `applyOptions` lifts `usage`, `reasoning`, and `prompt_cache_key` model options into the OpenRouter Chat payload. + +The important idea is that payload patches operate after protocol lowering but before payload validation and HTTP encoding. That gives providers a typed place to add `stream_options`, OpenRouter routing options, or other native fields without expanding the common request model for every provider. + +The tests to read are [`test/patch.test.ts`](./test/patch.test.ts), [`test/patch-pipeline.test.ts`](./test/patch-pipeline.test.ts), and [`test/adapter.test.ts`](./test/adapter.test.ts). + +## 9. Tools Are Typed End To End + +The public tutorial shows typed tools in [`example/tutorial.ts`](./example/tutorial.ts). The implementation is in [`src/tool.ts`](./src/tool.ts) and [`src/tool-runtime.ts`](./src/tool-runtime.ts). + +What is worth showing: + +- Tool definitions use Effect Schema for inputs and success values: [`src/tool.ts`](./src/tool.ts) +- Tool runtime streams model output, dispatches tool calls, validates results, and loops: [`src/tool-runtime.ts`](./src/tool-runtime.ts) +- Unknown tools, invalid input, and handler failures become model-visible tool errors: [`test/tool-runtime.test.ts`](./test/tool-runtime.test.ts) +- Provider-executed tools pass through without client dispatch: [`src/tool-runtime.ts`](./src/tool-runtime.ts) + +The common event model is what makes this work across providers. Providers emit `tool-input-delta`, `tool-call`, `tool-result`, and `request-finish` events; the runtime consumes those events and decides whether another model round is needed. + +## 10. Stream Parsers Are Small State Machines + +Each protocol's stream parser turns provider-native chunks into common events. + +Examples worth reading: + +- [`src/protocols/openai-chat.ts`](./src/protocols/openai-chat.ts) accumulates streamed tool JSON by numeric index and finalizes tool calls at `finish_reason`. +- [`src/protocols/openai-responses.ts`](./src/protocols/openai-responses.ts) handles item lifecycle events and hosted provider-executed tool items. +- [`src/protocols/anthropic-messages.ts`](./src/protocols/anthropic-messages.ts) merges usage from `message_start` and `message_delta`, and supports server tools. +- [`src/protocols/gemini.ts`](./src/protocols/gemini.ts) converts Gemini parts into text, reasoning, and tool-call events. +- [`src/protocols/bedrock-converse.ts`](./src/protocols/bedrock-converse.ts) parses AWS event-stream frames and waits for metadata to emit finish with usage. + +This is the part where provider APIs differ the most. The normalized result is still one `LLMEvent` stream. + +## 11. Deterministic Tests Cover The Parser Edge Cases + +Before live recordings, the package uses deterministic in-memory HTTP layers. + +Start with [`test/lib/http.ts`](./test/lib/http.ts): + +- `fixedResponse` returns one deterministic provider response body. +- `dynamicResponse` inspects the outgoing request and builds a response. +- `truncatedStream` simulates mid-stream transport failure. +- `scriptedResponses` drives multi-round tool loops with a sequence of responses. + +SSE helpers live in [`test/lib/sse.ts`](./test/lib/sse.ts). OpenAI chunk helpers live in [`test/lib/openai-chunks.ts`](./test/lib/openai-chunks.ts). + +Good tests to read: + +- [`test/provider/openai-chat.test.ts`](./test/provider/openai-chat.test.ts) covers request payloads, stream text, usage, tool-call streaming, malformed chunks, and HTTP errors. +- [`test/provider/openai-responses.test.ts`](./test/provider/openai-responses.test.ts) covers Responses item lifecycle, hosted tools, and provider errors. +- [`test/provider/anthropic-messages.test.ts`](./test/provider/anthropic-messages.test.ts) covers message blocks, reasoning, server tools, and usage merging. +- [`test/provider/gemini.test.ts`](./test/provider/gemini.test.ts) covers media input, schema conversion, reasoning, and finish reasons. +- [`test/provider/bedrock-converse.test.ts`](./test/provider/bedrock-converse.test.ts) covers binary event stream decoding, SigV4 auth boundaries, and Bedrock tool deltas. +- [`test/tool-runtime.test.ts`](./test/tool-runtime.test.ts) covers tool loop behavior without live model calls. + +These tests are fast because they never call a provider. They validate request bodies and parser behavior directly. + +## 12. The Cassette Recorder Is The Testing Story + +Recorded tests are the coolest part of the safety net. + +The wrapper is [`test/recorded-test.ts`](./test/recorded-test.ts). It builds on `@opencode-ai/http-recorder` and gives each live test a cassette name, metadata, filters, and credential gates. + +Recorded test files: + +- OpenAI Chat basic and tool flows: [`test/provider/openai-chat.recorded.test.ts`](./test/provider/openai-chat.recorded.test.ts) +- OpenAI Chat full tool loop: [`test/provider/openai-chat-tool-loop.recorded.test.ts`](./test/provider/openai-chat-tool-loop.recorded.test.ts) +- OpenAI Responses: [`test/provider/openai-responses.recorded.test.ts`](./test/provider/openai-responses.recorded.test.ts) +- Anthropic Messages: [`test/provider/anthropic-messages.recorded.test.ts`](./test/provider/anthropic-messages.recorded.test.ts) +- Gemini: [`test/provider/gemini.recorded.test.ts`](./test/provider/gemini.recorded.test.ts) +- OpenAI-compatible families: [`test/provider/openai-compatible-chat.recorded.test.ts`](./test/provider/openai-compatible-chat.recorded.test.ts) +- Bedrock Converse recorded cases: [`test/provider/bedrock-converse.test.ts`](./test/provider/bedrock-converse.test.ts) + +The shared recorded scenarios are in [`test/recorded-scenarios.ts`](./test/recorded-scenarios.ts). That file keeps live tests semantically comparable across providers: text generation, tool calls, tool loops, event summaries, and usage assertions. + +Cassettes live under [`test/fixtures/recordings`](./test/fixtures/recordings). They record HTTP request/response pairs, not just expected events, so replay exercises the real provider parser against captured wire data. + +## 13. How To Run Recordings + +Replay is the default. Missing cassettes are skipped unless you explicitly record. + +Common commands from `packages/llm`: + +```sh +bun run test +bun run test test/provider/openai-chat.test.ts +bun run test test/provider/openai-chat.recorded.test.ts +RECORDED_PROVIDER=openai bun run test +RECORDED_PREFIX=openai-chat bun run test +RECORDED_TEST="streams text" bun run test +``` + +Record intentionally: + +```sh +RECORD=true OPENAI_API_KEY=... bun run test test/provider/openai-chat.recorded.test.ts +``` + +Recorded filters are implemented in [`test/recorded-test.ts`](./test/recorded-test.ts): + +- `RECORDED_PREFIX` matches cassette groups such as `openai-chat`. +- `RECORDED_PROVIDER` matches metadata tags such as `provider:openai`. +- `RECORDED_TAGS` requires tags such as `tool` or `provider:togetherai`. +- `RECORDED_TEST` matches by test name, kebab id, or cassette path. + +The setup script is [`script/setup-recording-env.ts`](./script/setup-recording-env.ts). It helps populate `.env.local`, checks which provider credentials are present, and can verify recommended recording providers. + +The cost report script is [`script/recording-cost-report.ts`](./script/recording-cost-report.ts). It walks cassette files, extracts usage from provider response bodies, looks up pricing from `models.dev`, and prints estimated recording costs. + +## 14. Why This Design Is Nice + +The package gets several useful properties from this shape: + +- Simple use site from `LLM.generate`, provider model helpers, and `LLM.request` constructors. +- Provider code reuse from separating `Protocol`, `Endpoint`, `Auth`, and `Framing`. +- Native wire visibility because payload and chunk schemas stay close to lowering/parsing code. +- Safe provider quirks because patches transform provider payloads after lowering but before validation. +- Common UI/runtime events because every provider parser emits `LLMEvent`s. +- Tool-loop portability because `ToolRuntime` consumes common tool events instead of provider-specific streams. +- Fast parser tests from `fixedResponse`, `dynamicResponse`, and `scriptedResponses`. +- Real integration confidence because HTTP cassettes replay actual provider wire data. + +## 15.

- -### How Adapter Is Used Today - -Keeping the current names, an `Adapter` is the runnable implementation for one registered request route. - -It is selected from the model handle when the provider helper created the model in the same process.

It builds those methods by composing four pieces. - -```txt -Adapter.make(...) - = Protocol.prepare / payload Schema / chunk Schema / process - + Endpoint URL construction - + Auth header/signing behavior - + Framing bytes-to-frames behavior -``` - -`Protocol` no longer has a separate `encode` function in the normal path. The adapter validates payload patches and JSON-encodes the final payload from `protocol.payload`. - -So the current relationship is: - -```txt -ModelRef.protocol - -> selects Adapter after serialization / registry lookup - -> Adapter composes Protocol + Endpoint + Auth + Framing - -> Adapter compiles the request and parses the response -``` - -`model.provider` is still useful, but it is not the adapter lookup key. It identifies the deployment/product surface for defaults, capabilities, provider-specific options, patch predicates, debugging, telemetry, and OpenCode provider parity. - -The odd-looking case is OpenAI-compatible Chat.

Today it supports protocols/providers that the OpenCode bridge can map to known native model helpers and adapters, plus generic OpenAI-compatible deployments. A config-defined provider with `@ai-sdk/openai-compatible` can map to `openai-compatible-chat`; a brand-new protocol needs a native adapter and bridge mapping. - -The core package is now open enough for external protocols: `ProtocolID` is just a string, so a third-party package can define `Protocol.define(...)`, `Adapter.make(...)`, and a model helper without changing this package. To make OpenCode load those from config the same way it loads AI SDK packages, we would add an explicit native-provider loader/registry analogous to the AI SDK `model.api.npm` loader. diff --git a/packages/llm/ARCHITECTURE.use-site-to-internals.md b/packages/llm/ARCHITECTURE.use-site-to-internals.md deleted file mode 100644 index 11e00b959076..000000000000 --- a/packages/llm/ARCHITECTURE.use-site-to-internals.md +++ /dev/null @@ -1,336 +0,0 @@ -# LLM Architecture - -This package has one public shape: - -```ts -const model = OpenAI.model("gpt-4o-mini", { apiKey }) -const response = yield * LLM.generate({ model, prompt: "Say hello." }) -``` - -Everything below explains how that stays simple while still supporting OpenAI, Anthropic, Gemini, Bedrock, OpenRouter, Azure, local OpenAI-compatible gateways, provider quirks, hosted tools, cache hints, and request replay. - -Read from top to bottom.

It says which model to call, which provider owns the deployment, and which wire protocol can talk to it. - -```ts -OpenAI.model("gpt-4o-mini", { apiKey }) - -> provider: openai - -> protocol: openai-responses - -> id: gpt-4o-mini - -OpenRouter.model("openai/gpt-4o-mini", { apiKey }) - -> provider: openrouter - -> protocol: openai-compatible-chat - -> id: openai/gpt-4o-mini - -OpenAICompatible.model("gpt-4o-mini", { name: "local-gateway", baseURL }) - -> provider: local-gateway - -> protocol: openai-compatible-chat - -> id: gpt-4o-mini -``` - -This split is the core design choice. - -| Concept | Question it answers | -| -------------------------------------------- | ------------------------------------------------------------ | -| `provider` | Who is the deployment or product surface? | -| `protocol` | Which request/response shape should the runtime use? | -| `id` | Which model/deployment id should be sent? | -| `baseURL` | Where should HTTP go? | -| `apiKey`, `headers`, `queryParams`, `native` | What deployment-specific transport data is needed? | -| `capabilities`, `limits` | What normalized features and constraints should callers see? | - -Provider identity and wire protocol often differ. OpenRouter is not OpenAI, but many OpenRouter models speak enough OpenAI Chat shape to reuse the OpenAI Chat protocol. - -
-Conceptual ModelRef shape - -```ts -type ModelRef = { - id: ModelID - provider: ProviderID - protocol: ProtocolID - baseURL?: string - apiKey?: string - headers?: Record - queryParams?: Record - capabilities: ModelCapabilities - limits: ModelLimits - native?: Record -} -``` - -`ModelRef` is not a provider client. It does not send requests. It is the stable, serializable description of what should be called. - -
- -## 3. What Happens At Runtime - -At runtime, every request follows the same path. - -```txt -LLM.generate({ model, prompt }) - -> LLM.request(...) - -> LLMClient - -> adapter selected by model.protocol - -> provider-native payload - -> HttpClientRequest - -> RequestExecutor - -> provider response stream - -> LLMEvent stream - -> LLMResponse -``` - -The high-level API hides that pipeline. - -```ts -const response = - yield * - LLM.generate({ - model: OpenAI.model("gpt-4o-mini", { apiKey }), - prompt: "Say hello.", - }) -``` - -The lower-level runtime sees this shape. - -```ts -const request = LLM.request({ - model, - prompt: "Say hello.", -}) - -const client = LLMClient.make({ - adapters: [OpenAIResponses.adapter, OpenAIChat.adapter], - patches: ProviderPatch.defaults, -}) - -const response = yield * client.generate(request) -``` - -
-Adapter pipeline - -The adapter is selected by `request.model.protocol`. - -```ts -const adapter = adapters.get(request.model.protocol) -const draft = adapter.prepare(request) -const patched = applyTargetPatches(draft) -const target = adapter.validate(patched) -const http = adapter.toHttp(target) -const response = yield * RequestExecutor.execute(http) -const events = adapter.parse(response) -``` - -`generate` collects the same `LLMEvent` stream that `stream` exposes incrementally. - -
- -## 4. How Providers Are Built - -Provider behavior is split across reusable layers instead of one large provider class. - -```txt -Provider helper - creates ModelRef values - -Provider module - exports adapters and helper constructors - -Adapter - composes Protocol + Endpoint + Auth + Framing - -Protocol - owns provider-native request and stream semantics -``` - -The composition rule is: - -```txt -Adapter = Protocol + Endpoint + Auth + Framing -``` - -OpenAI Chat is a normal adapter composition. - -```ts -export const adapter = Adapter.make({ - id: "openai-chat", - protocol: OpenAIChat.protocol, - endpoint: Endpoint.baseURL({ - default: "https://api.openai.com/v1", - path: "/chat/completions", - }), - auth: Auth.openAI, - framing: Framing.sse, -}) -``` - -OpenAI-compatible Chat is the same protocol with different deployment axes. - -```txt -OpenAI-compatible Chat adapter - = OpenAIChat.protocol - + required baseURL endpoint - + bearer auth - + SSE framing -``` - -That is why these can share implementation without pretending they are the same provider. - -```ts -OpenAI.chat("gpt-4o-mini", { apiKey }) -OpenRouter.model("openai/gpt-4o-mini", { apiKey }) -OpenAICompatible.model("gpt-4o-mini", { name: "local-gateway", baseURL }) -``` - -
-Layer responsibilities - -| Layer | Owns | -| --------------- | ----------------------------------------------------------------------------------------- | -| Provider helper | Public constructor, defaults, provider identity, model capabilities, limits. | -| Provider module | Exported adapters and helpers passed to `LLM.layer({ providers })`. | -| Adapter | Runtime registration and composition. | -| Protocol | Request lowering, payload schema, chunk schema, stream state machine. | -| Endpoint | URL construction, base URL, path, query params, deployment routing. | -| Auth | Bearer tokens, API-key headers, SigV4, future IAM/AAD signing. | -| Framing | Bytes to frames before protocol parsing, usually SSE. | - -
- -
-When to add what - -| Need | Add | -| -------------------------------------------------------- | ----------------------------------------- | -| A new hosted product speaks an existing protocol | Provider helper plus adapter composition. | -| A provider has a unique request/response shape | New protocol plus adapter composition. | -| A provider has the same protocol but different auth | Reuse protocol, add auth axis. | -| A provider has the same protocol but different URL rules | Reuse protocol, add endpoint axis. | -| A provider streams non-SSE frames | Reuse or add protocol, add framing axis. | -| A model needs a one-off body tweak | Patch, not a common schema field. | - -
- -## 5. How Quirks Are Handled - -Patches are named, traceable provider/model transformations inspired by OpenCode's existing `ProviderTransform` layer. - -Use a patch when behavior is real but not universal enough to belong in the common request schema. - -```txt -cache.prompt-hints -anthropic.scrub-tool-call-ids -target.openai-chat.include-usage -``` - -Each patch has an id, phase, predicate, and reason. Applied patches appear in `patchTrace`. - -Patches are not a routing mechanism. Adapter selection happens from the original `request.model`; request patches may change payload details, but changing `model.provider`, `model.id`, or `model.protocol` is rejected. If a call needs a different provider, model, or protocol, construct a different model handle before building the request. - -The rule is: - -```txt -Common request shape stays small. -Provider quirks stay named and auditable. -Model routing stays explicit at the call site. -``` - -Good patch candidates include cache hint lowering, model-specific reasoning fields, OpenAI-compatible message cleanup, hosted-tool shape differences, metadata extraction, and provider option namespacing. - -Bad patch candidates are behaviors that every provider supports the same way. Those belong in the common request model. - -## 6. Why This Design - -AI SDK has an excellent use-site shape. - -```ts -openai("gpt-4o-mini") -openai.chat("gpt-4o-mini") -createOpenAICompatible({ baseURL })("gpt-4o-mini") -``` - -This package keeps the use-site shape familiar. - -```ts -OpenAI.model("gpt-4o-mini", { apiKey }) -OpenAI.chat("gpt-4o-mini", { apiKey }) -OpenAICompatible.model("gpt-4o-mini", { name, baseURL, apiKey }) -``` - -The difference is below the public API. - -| Concern | AI SDK | This package | -| ----------------------- | --------------------------------------------------------- | ----------------------------------------------------------------- | -| Use site | Provider creates runnable model object. | Provider creates `ModelRef`; `LLM` runtime runs it. | -| Provider implementation | Usually provider-package-specific language model classes. | Protocol, endpoint, auth, framing, and patches are separate axes. | -| OpenAI-compatible reuse | Dedicated OpenAI-compatible implementation. | Reuses `OpenAIChat.protocol` with different deployment axes. | -| Debug/replay/parity | Mostly hidden behind provider implementation. | Exposed through request lowering, patches, adapters, and events. | - -The tradeoff is intentional. The public API should feel small. The internals should be inspectable enough for OpenCode to preserve provider parity, replay HTTP, diff native payloads, and migrate provider-by-provider without cloning whole adapter classes. diff --git a/packages/llm/PROPOSAL.openai-compatible-wrappers.md b/packages/llm/PROPOSAL.openai-compatible-wrappers.md deleted file mode 100644 index 2d76073837c5..000000000000 --- a/packages/llm/PROPOSAL.openai-compatible-wrappers.md +++ /dev/null @@ -1,231 +0,0 @@ -# Proposal: OpenAI-Compatible Thin Wrappers - -## Summary - -Keep `OpenAICompatibleChat` as the shared implementation for providers that expose `/chat/completions`, but distinguish three levels of provider support: - -| Level | Use When | Example | -| --- | --- | --- | -| Profile | Provider only needs `provider`, `baseURL`, and capabilities. | DeepSeek text/tool basics, TogetherAI, Cerebras, Fireworks. | -| Thin wrapper | Provider speaks OpenAI Chat shape but needs named options, patches, capability defaults, metadata extraction, or provider-defined tools. | Mistral, Groq, Perplexity. | -| Dedicated protocol | Request lowering or stream parsing stops being OpenAI Chat-compatible. | Not justified for these providers yet. | - -The important rule: do not clone `OpenAIChat.protocol` for provider wrappers unless cassettes prove the wire format has diverged.

That cost is tiny compared with an LLM request, but it is still repeated work and repeated code. - -The patch pipeline can precompile the client-level patch set once: - -```ts -const pipeline = PatchPipeline.make(options.patches) -``` - -At construction time, the pipeline can: - -- Normalize `undefined`, a patch array, or a `PatchRegistry` into one internal shape. -- Group patches by phase. -- Sort each client-level phase by `order` and `id` once. -- Store empty-phase fast paths so requests with no patches avoid allocation-heavy plan construction. - -Per request, the pipeline still must evaluate `when(context)` predicates because predicates depend on the current request, model, protocol, metadata, tools, and provider. That part cannot be safely precompiled away unless a future patch type declares itself unconditional. - -Payload patches are slightly different because adapter-local payload patches vary by selected Adapter. Keep the first version simple: - -```ts -pipeline.patchPayload({ - state, - payload, - adapterPatches: adapter.patches, - validatePayload: adapter.validate, -}) -``` - -The pipeline can combine already-sorted client payload patches with adapter patches and apply the same ordering rule. If payload patch counts ever become large, the pipeline can cache the sorted merged payload patch list in a `WeakMap` keyed by the Adapter or by the adapter patch array. That is an internal Implementation optimization; the Interface does not need to expose it. - -The important simplicity win is bigger than the micro-performance win. `LLMClient` would stop describing the patch algorithm in five places. The pipeline becomes a reusable compiled patch lifecycle: one small Interface, one place to optimize, one place to test. - -## What The Module Owns - -The patch pipeline module should own: - -- Normalizing `PatchRegistry | ReadonlyArray | undefined` into a registry. -- Building fresh `PatchContext` after each request-shaped phase. -- Running request patches before prompt patches. -- Enforcing that request-shaped patches do not change `model.provider`, `model.id`, or `model.protocol`. -- Running tool-schema patches against every tool definition only when tools exist and patches matched. -- Emitting tool-schema trace once per matched patch, not once per tool. -- Combining request, prompt, tool-schema, and payload traces in lifecycle order. -- Combining adapter-local payload patches with client registry payload patches and applying the shared patch ordering rule. -- Invoking Adapter payload validation after payload patches. -- Applying stream patches to parsed `LLMEvent` streams with the compiled request context. - -It should not own: - -- Adapter lookup. -- Protocol lowering via `adapter.prepare(...)`. -- Payload validation Implementation. -- HTTP request construction. -- Provider-specific patch definitions. -- Provider stream parsing. - -Those remain behind the Adapter, Protocol, Endpoint, Auth, Framing, ProviderPatch, and RequestExecutor modules. - -## How This Cleans Up Code Elsewhere - -`src/adapter.ts` gets smaller and more navigable: - -- `normalizeRegistry(...)` moves out. -- `ensureSameRoute(...)` moves out. -- `compile(...)` stops constructing four separate plans. -- `compile(...)` stops manually refreshing contexts. -- `compile(...)` stops manually deciding when tool-schema traces count. -- `compile(...)` stops manually concatenating patch traces. -- `stream(...)` stops manually planning stream patches. - -`src/patch.ts` becomes clearer: - -- Patch constructors and predicates remain the primitive Interface. -- `plan(...)` can stay as an internal or low-level single-phase helper. -- Lifecycle semantics move to `src/patch-pipeline.ts` instead of being implied by Adapter tests. - -Provider patch modules stay focused: - -- `ProviderPatch.defaults` remains a list of provider facts. -- Provider-specific patches do not need to know lifecycle ordering. -- Adapter-local payload patches keep living on the selected Adapter. - -Tests get better locality: - -- Patch primitive tests stay in `patch.test.ts`. -- Patch lifecycle tests move to `patch-pipeline.test.ts`. -- Adapter tests keep only Adapter responsibilities and one end-to-end smoke test that `LLMClient` invokes the pipeline. - -## Why This Is Deepening - -The patch pipeline would be a deeper module because a small Interface hides a larger amount of behaviour. - -Current Interface: - -```ts -plan({ phase, context, patches }).apply(value) -``` - -That Interface is shallow because the caller must know the lifecycle. - -Proposed Interface: - -```ts -const pipeline = PatchPipeline.make(options.patches) -const request = yield* pipeline.patchRequest(input) -const payload = yield* pipeline.patchPayload({ state: request, payload, adapterPatches, validatePayload }) -const events = pipeline.patchStreamEvents({ request: payload.request, events }) -``` - -That Interface is deeper because callers get ordering, context refresh, route protection, tool-schema handling, payload patch composition, validation timing, stream mapping, and trace assembly without knowing each step. - -## Principles - -### Module - -Today, the real patch lifecycle is an unnamed module embedded in `LLMClient.compile(...)`. Naming it as a patch pipeline module gives it one Interface and one Implementation. - -### Interface - -The Interface becomes the test surface. Tests should ask what the pipeline guarantees: request patches run before prompt patches, contexts refresh, route changes fail, payload patches trace after tool-schema patches, validation runs after payload patches, and stream patches see the compiled request. - -### Depth - -The module becomes deep because callers learn a small lifecycle Interface instead of the full phase choreography. More behaviour sits behind less required knowledge. - -### Seam - -The seam moves from scattered calls to `plan(...)` into the patch pipeline Interface. The existing patch Interface remains the seam where provider-specific patch behaviour enters the lifecycle. - -### Adapter - -Provider-specific patches are Adapters at the patch seam: each concrete patch satisfies the patch Interface. Adapter-local payload patches remain local to the selected Adapter, but the pipeline owns how those patches combine with client registry payload patches. - -### Leverage - -Callers get more leverage because `LLMClient`, tests, and future request-compilation paths can reuse one lifecycle. A fix to context refresh or route protection pays back everywhere. - -### Locality - -Maintainers get more locality because patch bugs concentrate in the patch pipeline Implementation. Provider patches can stay focused on provider facts instead of lifecycle rules. - -### Deletion Test - -Deleting the current `plan(...)` helper removes only a small filter/sort/reduce. Deleting the proposed patch pipeline would make lifecycle complexity reappear in `LLMClient`, tests, and any future compilation path. That means the proposed module earns its keep. - -### One Adapter = Hypothetical Seam, Two Adapters = Real Seam - -This proposal does not add a speculative seam with fake alternative implementations. It deepens an existing real seam: many provider patches already satisfy the patch Interface, and adapter-local plus client registry payload patches already vary across providers and call sites. The missing piece is locality for the lifecycle that applies those Adapters. - -## Benefits - -Locality improves because lifecycle rules live in one module instead of being embedded in request compilation. - -Leverage improves because every provider patch and every client path gets the same ordering, trace, validation timing, and route-invariant behaviour. - -Tests improve because the patch pipeline Interface becomes the test surface. Instead of constructing fake protocols, fake adapters, fake framing, and scripted HTTP flows to verify patch lifecycle behaviour, tests can exercise the lifecycle directly. - -Useful tests: - -- Adapter selection happens before request patches. -- Request patches run before prompt patches. -- Prompt patch predicates see the request after request patches. -- Request-shaped patches cannot change `model.provider`, `model.id`, or `model.protocol`. -- Tool-schema patches are skipped when there are no tools. -- Tool-schema traces appear only when tool-schema patches ran. -- Tool-schema trace appears once per matched patch, not once per tool. -- Adapter payload patches and client registry payload patches follow the shared patch ordering rule. -- Payload validation runs after payload patches. -- Stream patches see the compiled request, not the original request. -- Pipeline construction accepts `undefined`, a patch array, or a `PatchRegistry`. - -## What Not To Do Yet - -Do not change the public patch definition shape unless the pipeline proves it needs a missing field. - -Do not create a full plugin system for patch ordering. - -Do not move provider-specific patch logic into the pipeline. - -Do not make payload patch typing more ambitious in this step; payload patches are already typed at adapter construction sites and erased in the registry. - -Do not move Adapter lookup, Protocol lowering, HTTP construction, or stream parsing into the pipeline. - -Do not change provider behaviour while extracting the lifecycle. - -## Migration Plan - -1. Add `src/patch-pipeline.ts` with the lifecycle Implementation and focused tests. -2. Keep `Patch.plan(...)` public during migration and use it internally inside the pipeline. -3. Move `normalizeRegistry(...)` and `ensureSameRoute(...)` from `src/adapter.ts` into the pipeline module. -4. Add `patchRequest(...)` that runs request, prompt, and tool-schema phases and returns a carried request state. -5. Add `patchPayload(...)` that applies adapter-local payload patches, client registry payload patches, Adapter validation, and returns a carried payload state with combined trace. -6. Add `patchStreamEvents(...)` that applies stream patches to parsed `LLMEvent` streams. -7. Add `test/patch-pipeline.test.ts` with lifecycle tests before changing `LLMClient`. -8. Replace handwritten phase choreography in `LLMClient.compile(...)` and `LLMClient.stream(...)` with the pipeline. -9. Keep one adapter-level smoke test proving `LLMClient` invokes patches end-to-end. -10. Move or delete adapter-level lifecycle tests that are now covered by patch pipeline tests. -11. Decide later whether `Patch.plan(...)` remains public or becomes internal. - -## Open Questions - -Should `Patch.plan(...)` remain public as a low-level primitive, or should the patch pipeline become the only exported lifecycle Interface? - -Should stream patches be part of the same pipeline module from the first extraction, or should the first extraction focus only on request-to-payload compilation? - -Should the pipeline return one combined trace array, or should it preserve phase-grouped traces internally for better debugging while exposing one ordered trace to callers? - -Should route protection apply only after request and prompt phases, or should the pipeline also assert that payload and stream phases cannot observe changed route state? - -Should payload patch ordering keep the current global `order`/`id` rule across adapter-local and client registry patches, or should adapter-local payload patches get an explicit ordering band before client registry payload patches? - -## Recommendation - -Do this before adding more provider-specific patches. The current shape is already correct enough to extract safely, and the next set of provider quirks will make patch ordering and conversation-shape rules more important. A patch pipeline module would turn implicit lifecycle knowledge into a deep Interface with better locality, better leverage, and a clearer test surface. diff --git a/packages/llm/TODO.provider-transform-parity.md b/packages/llm/TODO.provider-transform-parity.md index 98498ae3e001..ace27c79ffa7 100644 --- a/packages/llm/TODO.provider-transform-parity.md +++ b/packages/llm/TODO.provider-transform-parity.md @@ -2,22 +2,22 @@ This tracks OpenCode behavior from `packages/opencode/src/provider/transform.ts` that is not fully represented in `packages/llm` yet. -Patches are the right seam when the behavior is a provider/model quirk that mutates request history, tool schemas, target bodies, or stream events.

It preserves common call controls, keeps provider behavior exact, and gives a serializable escape hatch. + +2. **Accept the same option shape on models and calls.** Model options are defaults. Call options override. Variants resolve into the same shape before `LLM.stream` / `LLM.generate`. + +3. **Keep reasoning in `providerOptions` for now.** Use `providerOptions.openai.reasoningEffort`, `providerOptions.anthropic.thinking`, `providerOptions.gemini.thinkingConfig`, and `providerOptions.openrouter.reasoning`. Do not add generic `policy.reasoning` yet. + +4. **Add typed provider option schemas at provider facades.** Core can store `providerOptions` as a serializable record, but provider helpers should expose typed inputs and validate their namespace. + +5. **Add message/content-part provider options after call-level options.** AI SDK and Effect Smol both need provider-specific prompt annotations for cache control, file citations, image detail, reasoning metadata, and similar features. We should eventually support that shape too. + +6. **Keep `http` overlays last-resort and serializable.** Do not restore function transforms as the main extension point. Promote stable raw fields into typed `providerOptions` over time. + +7. **Do not use `native` for provider request options.** Reserve `native` only for genuinely runtime-private implementation details if we keep it at all. Public provider request behavior should be `providerOptions`. + +## Tracked Follow-Ups + +These are intentionally tracked separately from the initial call-option refactor: + +- **Message/content-part `providerOptions`.** Needed for provider-native prompt annotations such as Anthropic cache markers, OpenAI/Gemini image detail, file citation controls, and reasoning metadata. +- **Provider metadata on response parts/events.** Needed for reasoning signatures, citations, source documents, provider ids, and native usage/accounting details without adding provider-specific fields to common events. +- **Provider-specific schema transformers.** Structured output and tool schemas need provider-owned JSON Schema rewrites, especially for Gemini-style schema dialect differences. +- **Provider config defaults/overrides.** Model defaults plus call overrides cover most of Effect Smol's `withConfigOverride(...)` pattern; keep this in mind if provider-layer config grows beyond model refs. +- **Tool choice subsets.** Add a common way to say “one of these tools” in addition to `auto`, `none`, `required`, and one specific tool. + +## Current Code Delta + +Implemented in the current code direction: + +- `generation` exists on model defaults and requests, including `maxTokens`, `temperature`, `topP`, `topK`, `frequencyPenalty`, `presencePenalty`, `seed`, and `stop`. +- `providerOptions` exists on model defaults and requests; call-level provider namespaces override model defaults. +- `http` exists on model defaults and requests with serializable `body`, `headers`, and `query` overlays. +- Generic `policy`, request-level `reasoning`, and request-level `cache` were removed from the public LLM request/model shape. +- `native` remains only on `ModelRef`, `Message`, and `ToolDefinition` for runtime-private or round-trip implementation data. + +Recommended next code changes: + +1.

Extract Request, Response, And Provider Request IDs + +`statusError` must receive the original request. The current shape `statusError(response)` cannot populate request diagnostics reliably. + +Use a closure: + +```ts +const statusError = (request: HttpClientRequest.HttpClientRequest) => + (response: HttpClientResponse.HttpClientResponse) => + Effect.gen(function* () { + if (response.status < 400) return response + // construct ProviderRequestError with request + response diagnostics + }) +``` + +Or switch to `HttpClient.filterStatusOk` and map the resulting `StatusCodeError`, which carries both request and response.

Classify Retryable Status Responses Conservatively + +Automatic retry should initially apply only to explicit HTTP status responses where no model stream was handed to a parser. + +Default automatic retry statuses: + +- `429 Too Many Requests` +- `503 Service Unavailable` +- `504 Gateway Timeout` +- `529 Overloaded` used by Anthropic-style overload responses + +Do not include `409` in provider-neutral defaults. Effect-smol treats OpenAI `409` as invalid request-like behavior, and there is not enough provider evidence to retry it globally. + +Do not automatically retry transport timeouts / connection resets in the first patch. Marking them as diagnostically retryable can be considered later behind explicit opt-in, but default generation retries should not replay ambiguous `POST`s. + +Implementation helper: + +```ts +const retryableStatus = (status: number) => + status === 429 || status === 503 || status === 504 || status === 529 +``` + +Potential future additions after provider evidence: + +- `500`, `502` for transient provider failures. +- Cloudflare edge statuses such as `520`, `522`, `524` for OpenAI-compatible front doors. +- Provider-specific policies keyed by adapter/provider. + +### 5. Parse `Retry-After` And Simple Rate-Limit Headers + +Parse standard `Retry-After` forms: + +- Delta seconds: `Retry-After: 3` +- HTTP date: `Retry-After: Wed, 21 Oct 2015 07:28:00 GMT` + +Also accept `retry-after-ms` when present. + +```ts +const retryAfterMs = (headers: Record) => { + const normalized = normalizedHeaders(headers) + const millis = Number(normalized["retry-after-ms"]) + if (Number.isFinite(millis)) return Math.max(0, millis) + + const value = normalized["retry-after"] + if (!value) return undefined + + const seconds = Number(value) + if (Number.isFinite(seconds)) return Math.max(0, seconds * 1000) + + const date = Date.parse(value) + if (!Number.isNaN(date)) return Math.max(0, date - Date.now()) + + return undefined +} +``` + +Keep raw redacted headers on `HttpResponseDetails` so callers can inspect provider-specific rate-limit headers such as `x-ratelimit-*`, `anthropic-ratelimit-*`, or AWS/Gemini equivalents without the executor knowing every provider shape. + +### 6. Add Conservative Pre-Stream Retry In `RequestExecutor` + +Retry should live in `src/adapter/executor.ts`, not in each adapter. + +The executor owns this boundary: + +```txt +compile request -> execute HTTP request -> receive response -> parse stream +``` + +Automatic retry is allowed only before `execute` returns a successful response. After that, stream consumers own the response and retrying could duplicate text, tool calls, hosted tool side effects, or token charges. + +Default retry policy: + +- `maxRetries`: `2` +- Base delay: `500ms` +- Max delay: `10s` +- Jitter: enabled when no `retryAfterMs` is present +- Honor `retryAfterMs` when present, capped by max delay in the first patch +- Retry predicate: only `ProviderRequestError` with `retryable === true` + +Use Effect scheduling primitives if the v4 API can express error-dependent delay cleanly. If not, keep a small private helper rather than exposing retry machinery publicly. + +The shape should be similar to: + +```ts +const executeOnce = (request: HttpClientRequest.HttpClientRequest) => + http.execute(request).pipe( + Effect.mapError(toHttpError), + Effect.flatMap(statusError(request)), + ) + +execute: (request) => executeOnce(request).pipe(retryStatusFailures(defaultRetryPolicy)) +``` + +`retryStatusFailures` should stay private until there is a concrete external need. + +### 7. Future Retry Configuration Requires Executor Context + +Do not add `HttpOptions.retry` in the first patch. + +`RequestExecutor.execute` currently receives only `HttpClientRequest.HttpClientRequest`. It does not receive the original `LLMRequest`, merged model/request `HttpOptions`, adapter ID, provider ID, or generation/tool context. + +Per-request retry configuration requires one of these changes first: + +```ts +execute: (input: { + readonly http: HttpClientRequest.HttpClientRequest + readonly request: LLMRequest +}) => Effect.Effect +``` + +or: + +```ts +execute: ( + http: HttpClientRequest.HttpClientRequest, + context: RequestExecutor.Context, +) => Effect.Effect +``` + +Defer that API change until default diagnostics and conservative status retry are proven useful. + +## Implementation Plan + +1. Add `HttpRequestDetails` and `HttpResponseDetails` schema classes. +2. Optionally add `HttpRateLimitDetails` if it stays provider-neutral. +3. Extend `ProviderRequestError` and `TransportError` with diagnostics and retry hints. +4. Add executor helpers for header normalization, redaction, URL redaction, body truncation, request details, response details, request IDs, retryable status classification, and `Retry-After` parsing. +5. Change `statusError(response)` to `statusError(request)(response)` or equivalent so rich request diagnostics are available. +6. Populate rich `ProviderRequestError` for non-2xx status responses. +7. Populate richer `TransportError` where the underlying HTTP client error exposes a request, but do not retry transport errors by default. +8. Add private conservative retry around `executeOnce` for retryable status responses only. +9. Add deterministic tests for diagnostics, redaction, `Retry-After`, retryable statuses, non-retryable statuses, retry attempts, and no retry after stream parsing begins. + +## Tests + +Add or extend tests under `packages/llm/test`: + +- A `429` response returns `ProviderRequestError` with `retryable: true`, parsed `retryAfterMs`, redacted request headers, redacted response headers, redacted URL query secrets, and request ID. +- A `529` response is treated as retryable. +- A `401` response returns `ProviderRequestError` with `retryable: false` or `undefined`, not retried. +- A `503` followed by a successful SSE response retries exactly once and streams normally. +- A repeated `429` retries up to the default limit, then returns the final enriched error. +- Authorization-like request headers are redacted in the error. +- Query-string secrets are redacted in `request.url`. +- Non-secret headers remain visible for diagnostics. +- Response bodies are truncated and set `bodyTruncated: true` when above the cap. +- Transport timeout or connection errors become `TransportError` diagnostics but are not retried by default. +- Invalid URL or encode failures become `TransportError` with `retryable: false` or `undefined`. +- A first response of `200` with one valid SSE event followed by malformed data is attempted exactly once and fails as a stream/chunk parse error, proving executor retry does not replay partial streams. + +Use deterministic scripted HTTP responses over live provider calls. Use a controlled clock or a test-only short retry policy so retry tests are not slow or flaky. Do not add recorded cassettes for retry behavior unless a real provider behavior must be captured. + +## Open Questions + +- Should explicit `Retry-After` be allowed to exceed `maxDelayMs`, or should the first implementation cap it for responsiveness? +- Should response body redaction go beyond truncation in the first patch, and can recorder secret scanning be reused safely? +- Should `ProviderRequestError` distinguish `rateLimited: true` from generic `retryable: true`, or is `status === 429` sufficient? +- Should default retry later include `500`, `502`, `520`, `522`, or `524` after OpenAI-compatible provider evidence? +- Should ambiguous transport retries be opt-in through a future executor context once the API can see provider/model/request settings? + +## Recommended First Patch Boundary + +Include diagnostics, redaction for headers and URL query params, response body truncation, request ID extraction, conservative retry classification, `Retry-After` parsing, and default pre-stream retries for explicit rate-limit / overload status responses. + +Defer provider-specific error body parsing, public retry configuration, ambiguous transport retries, and broad 5xx retry defaults until after the executor behavior is tested against OpenAI, Anthropic, Gemini, OpenAI-compatible providers, and Bedrock deterministic fixtures. diff --git a/packages/llm/example/tutorial.ts b/packages/llm/example/tutorial.ts index 1b654d4811c8..e93545e55ed3 100644 --- a/packages/llm/example/tutorial.ts +++ b/packages/llm/example/tutorial.ts @@ -1,5 +1,5 @@ import { Effect, Formatter, Layer, Schema, Stream } from "effect" -import { LLM, LLMClient, Tool } from "@opencode-ai/llm" +import { LLM, LLMClient, Tool, ToolRuntime } from "@opencode-ai/llm" import { Adapter, Auth, Endpoint, Framing, Protocol, RequestExecutor } from "@opencode-ai/llm/adapter" import { OpenAI } from "@opencode-ai/llm/providers" @@ -27,9 +27,8 @@ const model = OpenAI.model("gpt-4o-mini", { }, }) -// 2.

internally for built-ins, and let OpenCode dynamically import third-party packages that export the same definition. + +This should not introduce a second provider abstraction. `Adapter.model(...)` remains the lower-level primitive for turning one adapter route into a model factory. `Provider.Definition` is the uniform provider facade: an ID, a default `model(...)` factory, and optional named APIs such as `chat` or `responses`. + +Do not reuse the existing `models.dev` `npm` field for native routing. That field currently means "AI SDK provider package" and is part of OpenCode's existing fallback path. Add a separate native metadata field instead. + +## Problem + +OpenCode's current provider loading path can import arbitrary AI SDK provider packages because the AI SDK already defines the package contract: + +- Metadata names an npm package like `@ai-sdk/openai`. +- OpenCode imports that package. +- OpenCode finds a `create*` export. +- OpenCode calls the factory with `{ name, apiKey, baseURL, headers, ...options }`. +- The returned object implements the AI SDK model interface. + +The native `@opencode-ai/llm` path has no equivalent package contract yet. A native model cannot be resolved from an npm package name alone because it must know: + +- Which public model factory to call. +- Which model API, if any, should be selected explicitly. +- Which endpoint and base URL rules apply. +- Which auth renderer applies. +- Which provider option namespace and option lowering apply. +- Which model capabilities and limits OpenCode should attach. +- Which provider-specific behavior belongs in code rather than `models.dev` data. + +The current OpenCode bridge therefore uses a local table from AI SDK package identifiers to built-in native provider helpers. That is good enough for migration, but not enough for third-party native providers. + +## Goals + +- Let third parties publish native OpenCode LLM providers as npm packages. +- Make provider packages explicit and type-checkable instead of guessing export names. +- Keep built-in providers and external packages using one self-similar provider interface. +- Reuse `Adapter.model(...)` as the implementation primitive instead of creating a competing model factory abstraction. +- Keep `models.dev` metadata declarative and serializable. +- Keep provider-specific signing, parsing, URL construction, and option lowering in code. +- Preserve the existing AI SDK provider path as a fallback while native support rolls out. +- Support OpenAI-compatible provider families without requiring a new package for every base URL. + +## Non-Goals + +- Do not dynamically import arbitrary packages and guess a `create*` export for native providers. +- Do not encode protocol parsers, auth signing logic, stream framing, or arbitrary functions in `models.dev`. +- Do not make every provider option portable across providers. +- Do not require immediate extraction of every built-in provider into its own package. +- Do not remove the AI SDK path as part of this design. + +## Recommended Shape + +Add a first-class provider definition contract to `@opencode-ai/llm`. A native provider package is simply an npm package that exports a `Provider.Definition`. + +```ts +export interface Definition { + readonly id: ProviderID + readonly model: Factory + readonly apis?: Record +} + +export type ModelFactory = ( + id: string | ModelID, + options?: Options, +) => ModelRef + +export type ModelOptions = Omit + +type AnyModelFactory = (...args: never[]) => ModelRef + +export const make = (definition: DefinitionType) => definition +``` + +The contract is intentionally close to what provider modules already export today: + +- `id`: native provider ID. +- `model`: default model factory. +- `apis`: optional named factories for providers with multiple first-class APIs. + +Provider IDs and model IDs should use the existing branded types from `src/schema.ts`: `ProviderID` and `ModelID`. Public factories may accept `string | ModelID` for ergonomics, but they normalize to branded IDs at the boundary before constructing a `ModelRef`. + +The model factory shape is fixed on purpose: `(id, options) => ModelRef`. Provider-specific differences belong in the options type, not in positional arguments. `Provider.make(...)` preserves each provider's actual option type, including whether options are optional or required. + +`Provider.Definition.model(...)` should usually be implemented with `Adapter.model(...)` or existing protocol helpers. The layers are: + +```text +Protocol + Endpoint + Auth + Framing -> Adapter +Adapter.model(...) -> route-specific model factory +Provider.Definition -> uniform provider facade / package contract +``` + +Adapters are deliberately not part of the provider package contract. They are implementation details owned by the model factories. `Adapter.make(...)` registers runnable adapters when a provider module is loaded, and `Adapter.model(...)` also ensures the selected adapter is registered when a model factory is called. Keeping adapter lists out of `Provider.Definition` avoids a second source of truth. + +Provider packages export a provider definition that is both the dynamic-loading contract and the direct user-facing entry point: + +```ts +import { Provider } from "@opencode-ai/llm/provider" +import * as OpenRouter from "./openrouter" + +export const provider = Provider.make({ + id: ProviderID.make("openrouter"), + model: OpenRouter.model, +}) + +export const model = provider.model +export default provider +``` + +Direct users can consume the definition instead of a separate helper namespace: + +```ts +import OpenRouter from "@opencode-ai/llm-provider-openrouter" + +const model = OpenRouter.model("openai/gpt-4o-mini", { apiKey }) +``` + +Named exports are convenience aliases for users who prefer `import { model } from ...`; they should point back to the provider definition rather than duplicating implementation. + +Providers with multiple public model APIs expose those factories without making OpenCode know provider-specific function names: + +```ts +export const provider = Provider.make({ + id: ProviderID.make("openai"), + model: OpenAI.model, + apis: { + responses: OpenAI.responses, + chat: OpenAI.chat, + }, +}) + +export const model = provider.model +export const responses = provider.apis.responses +export const chat = provider.apis.chat +export default provider +``` + +Direct users can still write `OpenAI.responses(...)` or `OpenAI.chat(...)`, but those helpers should be aliases of the provider definition. The provider definition is the source of truth; dynamic loaders and direct users consume the same object. + +This mirrors the AI SDK OpenAI provider shape: `openai(modelId)` is the default factory, while `openai.responses(modelId)`, `openai.chat(modelId)`, and `openai.completion(modelId)` explicitly select an OpenAI API. + +## OpenCode Resolve Input + +OpenCode still needs to translate `models.dev` and config into provider model options. That translation should live in the OpenCode bridge, not in a separate plugin-only API. + +```ts +type NativeProviderModelInput = Provider.ModelOptions & { + readonly apiID: string + readonly apiURL?: string +} +``` + +Bridge rule: + +```ts +const factory = native.api ? provider.apis?.[native.api] : provider.model +return factory?.(input.apiID, { + ...input.options, + apiKey: input.apiKey, + baseURL: input.apiURL, + headers: input.headers, + capabilities: input.capabilities, + limits: input.limits, + providerOptions: input.providerOptions, +}) +``` + +That keeps provider modules self-similar. Built-ins, external packages, and OpenCode all call the same `model(id, options)` shape. + +## Ideal Usage API + +The public use site should feel like AI SDK's provider objects, but return native `ModelRef` values. + +Default provider API: + +```ts +import { LLM } from "@opencode-ai/llm" +import { OpenAI } from "@opencode-ai/llm/providers" + +const model = OpenAI.model("gpt-5", { + apiKey, + providerOptions: { + openai: { store: false }, + }, +}) + +const request = LLM.request({ + model, + prompt: "Explain this in one paragraph.", +}) +``` + +Explicit provider model API, for providers with more than one first-class API: + +```ts +const responsesModel = OpenAI.apis.responses("gpt-5", { apiKey }) +const chatModel = OpenAI.apis.chat("gpt-4o", { apiKey }) +``` + +Named aliases can exist for ergonomics, but they should be aliases of the provider definition: + +```ts +const responsesModel = OpenAI.responses("gpt-5", { apiKey }) +const chatModel = OpenAI.chat("gpt-4o", { apiKey }) +``` + +Third-party providers should look the same: + +```ts +import Acme from "@acme/opencode-llm-provider" + +const model = Acme.model("acme-large", { + apiKey, + baseURL: "https://llm.acme.test/v1", +}) +``` + +OpenCode's dynamic path should consume the same object the user sees: + +```ts +const provider = await loadProviderDefinition(native.npm) +const create = native.api ? provider.apis?.[native.api] : provider.model +const model = create?.(apiID, options) +``` + +The important invariant: there is no plugin-only shape. The default export from a provider package is the user-facing provider object and the dynamic-loading contract. + +## Metadata + +Keep AI SDK metadata and native metadata separate. + +```json +{ + "npm": "@openrouter/ai-sdk-provider", + "opencode": { + "provider": "openrouter", + "npm": "@opencode-ai/llm-provider-openrouter" + } +} +``` + +For built-in providers, `opencode.npm` can be omitted: + +```json +{ + "npm": "@ai-sdk/openai", + "opencode": { + "provider": "openai" + } +} +``` + +For OpenAI-compatible providers that only need a base URL/profile, use a built-in generic native provider: + +```json +{ + "npm": "@ai-sdk/openai-compatible", + "api": "https://api.example.com/v1", + "opencode": { + "provider": "openai-compatible" + } +} +``` + +Model-level overrides may refine the provider model API without replacing the whole provider: + +```json +{ + "provider": { + "npm": "@ai-sdk/azure", + "opencode": { + "provider": "azure", + "api": "chat" + } + } +} +``` + +Recommended metadata fields: + +```ts +type ModelsDevProviderNative = { + readonly provider: string + readonly npm?: string + readonly api?: string + readonly profile?: string +} +``` + +`provider` selects a native provider definition. `npm` optionally names an external native provider package. `api` selects a named provider API such as `chat` or `responses`. `profile` is a declarative hint that built-in generic providers may use; it is not executable code. + +## Resolution Flow + +OpenCode's native bridge should resolve a model in this order: + +1. Read `model.provider.opencode` if present, otherwise `provider.opencode`. +2. If `opencode.npm` is present, dynamically import that package and validate its default export as a `Provider.Definition`. +3. Otherwise find a built-in plugin by `opencode.provider`. +4. If no native metadata exists, fall back to the temporary compatibility map from AI SDK package names to built-in plugins. +5. Translate OpenCode's `Provider.Info` and `Provider.Model` into provider model options. +6. Select `provider.apis[opencode.api]` when an API is present, otherwise use `provider.model`. +7. Call the selected model factory with `apiID` and model options to get a `ModelRef`. +8. If no provider or model API exists, treat the model as unsupported by the native path and fall back to the AI SDK path. + +The compatibility map should be treated as migration glue, not the long-term source of truth. + +## Built-In Providers + +Built-ins should use the same provider definition contract as external packages. + +```ts +export const openai = Provider.make({ + id: ProviderID.make("openai"), + model: OpenAI.model, + apis: { + responses: OpenAI.responses, + chat: OpenAI.chat, + }, +}) +``` + +`@opencode-ai/llm/providers` can continue exporting helper namespaces for direct users. A new registry module can export plugins: + +```ts +export const builtins = { + openai, + anthropic, + google, + azure, + openrouter, + "openai-compatible": openAICompatible, +} +``` + +This keeps OpenCode's bridge generic while preserving the ergonomic direct API: + +```ts +const model = OpenAI.model("gpt-5", { apiKey }) +``` + +## Package Boundaries + +Keep provider implementations in-tree until the plugin API stabilizes. Extract later where package boundaries provide real value. + +Good extraction candidates: + +- `@opencode-ai/llm-provider-bedrock`: AWS SigV4, event-stream framing, region/profile handling. +- `@opencode-ai/llm-provider-vertex`: Google auth, project/location routing, Gemini and Anthropic variants. +- `@opencode-ai/llm-provider-openrouter`: OpenRouter-specific routing, usage, reasoning, cache, and provider selection fields. +- `@opencode-ai/llm-provider-azure`: Azure resource/deployment URL policy and API-key/AAD auth. + +Keep shared code in `@opencode-ai/llm`: + +- Protocols such as OpenAI Chat, OpenAI Responses, Anthropic Messages, Gemini, and Bedrock Converse. +- Adapter primitives: `Adapter`, `Endpoint`, `Auth`, `Framing`, `Protocol`. +- Shared OpenAI-compatible profiles and helpers where they are broadly reusable. + +Do not create one package per provider before the API is proven. Start with built-ins implementing the provider definition contract, then extract providers that have enough special logic or dependency weight to justify it. + +## Dynamic Import Contract + +Native provider package loading should be strict. + +Accept: + +```ts +export default Provider.make({ ... }) +``` + +Optionally accept a named export for CommonJS or package-author convenience: + +```ts +export const provider = Provider.make({ ... }) +``` + +Reject packages that only export arbitrary functions like `createOpenAI`. A bare `model` export is useful for direct users, but the dynamic loader needs the full provider definition so it can validate `id` and select named `apis` uniformly. + +Validation should check: + +- `id` is a non-empty string. +- `model` is a function. +- `apis`, when present, is a record of functions. + +Provider definitions should not receive secrets through global state. OpenCode passes `apiKey` or `auth` material explicitly through model options. + +## Option Mapping + +The OpenCode bridge owns translation from OpenCode/models.dev options into provider model options. + +Provider definitions own provider-specific interpretation. + +For example, OpenCode can pass: + +```ts +{ + providerOptions: { + openrouter: { + usage: true, + reasoning: { effort: "high" }, + }, + }, +} +``` + +The OpenRouter provider decides how that becomes payload fields. Models.dev should not know the wire field names beyond declarative provider option defaults. + +## Security And Operational Policy + +Dynamic native plugins execute code. Treat them like current AI SDK provider packages: + +- Only load packages named by user config, local models.dev metadata, or trusted models.dev metadata. +- Keep package installation in the existing npm cache/install mechanism. +- Do not load native plugin packages for the default native path unless native mode is enabled or the provider is explicitly allowlisted. +- Log provider package, version if available, provider ID, and available model APIs. +- Avoid printing secrets in plugin load failures. + +## Migration Plan + +1. Add `Provider.Definition`, `Provider.ModelOptions`, `Provider.ModelFactory`, and `Provider.make` to `@opencode-ai/llm`. +2. Add built-in provider definitions next to existing helper namespaces. +3. Replace OpenCode's native bridge provider table with a registry lookup against built-in plugins. +4. Keep the AI SDK package compatibility map as a fallback while models.dev metadata catches up. +5. Extend OpenCode's models.dev schemas to parse optional `opencode` metadata. +6. Add dynamic import support for `opencode.npm` behind the existing native feature flag. +7. Add deterministic tests for built-in registry resolution, dynamic plugin loading, validation failures, and AI SDK fallback. +8. Update models.dev to emit native metadata for built-in providers. +9. Dogfood external package loading with one provider package before documenting the contract as stable. +10. Extract heavier providers into subpackages only after the contract survives OpenCode integration. + +## Open Questions + +- Should provider `model` return `Effect.Effect` instead of a synchronous value? Synchronous is simpler and matches current helpers, but Vertex/AWS credential discovery may eventually prefer Effect. +- Should `opencode.api` be a generic hint, or should each provider define its own accepted metadata shape? Generic hints are easier for models.dev, but provider-specific metadata is more type-accurate. +- Should external provider packages depend on `@opencode-ai/llm` as a peer dependency to avoid duplicate adapter registries? Probably yes. +- Should the native path allow custom local `file://` plugin packages the same way the AI SDK path does? Probably yes for development and enterprise providers. + +## Recommendation + +Build the native provider definition contract before adding many more one-off bridge mappings. + +Keep the current bridge as migration glue, but make built-ins implement the same `Provider.Definition` contract intended for third-party packages. That gives OpenCode a clean long-term story: + +- AI SDK metadata keeps powering the existing path. +- Native metadata selects native providers. +- Built-ins and external packages use the same interface. +- Provider-specific behavior lives in code, not in `models.dev` data. +- Third-party providers can plug in without OpenCode guessing export names or copying AI SDK's contract by accident.

A native model cannot be resolved from an npm package name alone because it must know: - -- Which public model factory to call. -- Which model API, if any, should be selected explicitly. -- Which endpoint and base URL rules apply. -- Which auth renderer applies. -- Which provider option namespace and option lowering apply. -- Which model capabilities and limits OpenCode should attach. -- Which provider-specific behavior belongs in code rather than `models.dev` data. - -The current OpenCode bridge therefore uses a local table from AI SDK package identifiers to built-in native provider helpers.

Public factories may accept `string | ModelID` for ergonomics, but they normalize to branded IDs at the boundary before constructing a `ModelRef`. - -The model factory shape is fixed on purpose: `(id, options) => ModelRef`. Provider-specific differences belong in the options type, not in positional arguments. `Provider.make(...)` preserves each provider's actual option type, including whether options are optional or required. - -`Provider.Definition.model(...)` should usually be implemented with `Adapter.model(...)` or existing protocol helpers. The layers are: - -```text -Protocol + Endpoint + Auth + Framing -> Adapter -Adapter.model(...) -> route-specific model factory -Provider.Definition -> uniform provider facade / package contract -``` - -Adapters are deliberately not part of the provider package contract. They are implementation details owned by the model factories. `Adapter.make(...)` registers runnable adapters when a provider module is loaded, and `Adapter.model(...)` also ensures the selected adapter is registered when a model factory is called. Keeping adapter lists out of `Provider.Definition` avoids a second source of truth. - -Provider packages export a provider definition that is both the dynamic-loading contract and the direct user-facing entry point: - -```ts -import { Provider } from "@opencode-ai/llm/provider" -import * as OpenRouter from "./openrouter" - -export const provider = Provider.make({ - id: ProviderID.make("openrouter"), - model: OpenRouter.model, -}) - -export const model = provider.model -export default provider -``` - -Direct users can consume the definition instead of a separate helper namespace: - -```ts -import OpenRouter from "@opencode-ai/llm-provider-openrouter" - -const model = OpenRouter.model("openai/gpt-4o-mini", { apiKey }) -``` - -Named exports are convenience aliases for users who prefer `import { model } from ...`; they should point back to the provider definition rather than duplicating implementation. - -Providers with multiple public model APIs expose those factories without making OpenCode know provider-specific function names: - -```ts -export const provider = Provider.make({ - id: ProviderID.make("openai"), - model: OpenAI.model, - apis: { - responses: OpenAI.responses, - chat: OpenAI.chat, - }, -}) - -export const model = provider.model -export const responses = provider.apis.responses -export const chat = provider.apis.chat -export default provider -``` - -Direct users can still write `OpenAI.responses(...)` or `OpenAI.chat(...)`, but those helpers should be aliases of the provider definition. The provider definition is the source of truth; dynamic loaders and direct users consume the same object. - -This mirrors the AI SDK OpenAI provider shape: `openai(modelId)` is the default factory, while `openai.responses(modelId)`, `openai.chat(modelId)`, and `openai.completion(modelId)` explicitly select an OpenAI API. - -## OpenCode Resolve Input - -OpenCode still needs to translate `models.dev` and config into provider model options. That translation should live in the OpenCode bridge, not in a separate plugin-only API. - -```ts -type NativeProviderModelInput = Provider.ModelOptions & { - readonly apiID: string - readonly apiURL?: string -} -``` - -Bridge rule: - -```ts -const factory = native.api ? provider.apis?.[native.api] : provider.model -return factory?.(input.apiID, { - ...input.options, - apiKey: input.apiKey, - baseURL: input.apiURL, - headers: input.headers, - capabilities: input.capabilities, - limits: input.limits, - providerOptions: input.providerOptions, -}) -``` - -That keeps provider modules self-similar. Built-ins, external packages, and OpenCode all call the same `model(id, options)` shape. - -## Ideal Usage API - -The public use site should feel like AI SDK's provider objects, but return native `ModelRef` values. - -Default provider API: - -```ts -import { LLM } from "@opencode-ai/llm" -import { OpenAI } from "@opencode-ai/llm/providers" - -const model = OpenAI.model("gpt-5", { - apiKey, - providerOptions: { - openai: { store: false }, - }, -}) - -const request = LLM.request({ - model, - prompt: "Explain this in one paragraph.", -}) -``` - -Explicit provider model API, for providers with more than one first-class API: - -```ts -const responsesModel = OpenAI.apis.responses("gpt-5", { apiKey }) -const chatModel = OpenAI.apis.chat("gpt-4o", { apiKey }) -``` - -Named aliases can exist for ergonomics, but they should be aliases of the provider definition: - -```ts -const responsesModel = OpenAI.responses("gpt-5", { apiKey }) -const chatModel = OpenAI.chat("gpt-4o", { apiKey }) -``` - -Third-party providers should look the same: - -```ts -import Acme from "@acme/opencode-llm-provider" - -const model = Acme.model("acme-large", { - apiKey, - baseURL: "https://llm.acme.test/v1", -}) -``` - -OpenCode's dynamic path should consume the same object the user sees: - -```ts -const provider = await loadProviderDefinition(native.npm) -const create = native.api ? provider.apis?.[native.api] : provider.model -const model = create?.(apiID, options) -``` - -The important invariant: there is no plugin-only shape. The default export from a provider package is the user-facing provider object and the dynamic-loading contract. - -## Metadata - -Keep AI SDK metadata and native metadata separate. - -```json -{ - "npm": "@openrouter/ai-sdk-provider", - "opencode": { - "provider": "openrouter", - "npm": "@opencode-ai/llm-provider-openrouter" - } -} -``` - -For built-in providers, `opencode.npm` can be omitted: - -```json -{ - "npm": "@ai-sdk/openai", - "opencode": { - "provider": "openai" - } -} -``` - -For OpenAI-compatible providers that only need a base URL/profile, use a built-in generic native provider: - -```json -{ - "npm": "@ai-sdk/openai-compatible", - "api": "https://api.example.com/v1", - "opencode": { - "provider": "openai-compatible" - } -} -``` - -Model-level overrides may refine the provider model API without replacing the whole provider: - -```json -{ - "provider": { - "npm": "@ai-sdk/azure", - "opencode": { - "provider": "azure", - "api": "chat" - } - } -} -``` - -Recommended metadata fields: - -```ts -type ModelsDevProviderNative = { - readonly provider: string - readonly npm?: string - readonly api?: string - readonly profile?: string -} -``` - -`provider` selects a native provider definition. `npm` optionally names an external native provider package. `api` selects a named provider API such as `chat` or `responses`. `profile` is a declarative hint that built-in generic providers may use; it is not executable code. - -## Resolution Flow - -OpenCode's native bridge should resolve a model in this order: - -1. Read `model.provider.opencode` if present, otherwise `provider.opencode`. -2. If `opencode.npm` is present, dynamically import that package and validate its default export as a `Provider.Definition`. -3. Otherwise find a built-in plugin by `opencode.provider`. -4. If no native metadata exists, fall back to the temporary compatibility map from AI SDK package names to built-in plugins. -5. Translate OpenCode's `Provider.Info` and `Provider.Model` into provider model options. -6. Select `provider.apis[opencode.api]` when an API is present, otherwise use `provider.model`. -7. Call the selected model factory with `apiID` and model options to get a `ModelRef`. -8. If no provider or model API exists, treat the model as unsupported by the native path and fall back to the AI SDK path. - -The compatibility map should be treated as migration glue, not the long-term source of truth. - -## Built-In Providers - -Built-ins should use the same provider definition contract as external packages. - -```ts -export const openai = Provider.make({ - id: ProviderID.make("openai"), - model: OpenAI.model, - apis: { - responses: OpenAI.responses, - chat: OpenAI.chat, - }, -}) -``` - -`@opencode-ai/llm/providers` can continue exporting helper namespaces for direct users. A new registry module can export plugins: - -```ts -export const builtins = { - openai, - anthropic, - google, - azure, - openrouter, - "openai-compatible": openAICompatible, -} -``` - -This keeps OpenCode's bridge generic while preserving the ergonomic direct API: - -```ts -const model = OpenAI.model("gpt-5", { apiKey }) -``` - -## Package Boundaries - -Keep provider implementations in-tree until the plugin API stabilizes. Extract later where package boundaries provide real value. - -Good extraction candidates: - -- `@opencode-ai/llm-provider-bedrock`: AWS SigV4, event-stream framing, region/profile handling. -- `@opencode-ai/llm-provider-vertex`: Google auth, project/location routing, Gemini and Anthropic variants. -- `@opencode-ai/llm-provider-openrouter`: OpenRouter-specific routing, usage, reasoning, cache, and provider selection fields. -- `@opencode-ai/llm-provider-azure`: Azure resource/deployment URL policy and API-key/AAD auth. - -Keep shared code in `@opencode-ai/llm`: - -- Protocols such as OpenAI Chat, OpenAI Responses, Anthropic Messages, Gemini, and Bedrock Converse. -- Adapter primitives: `Adapter`, `Endpoint`, `Auth`, `Framing`, `Protocol`. -- Shared OpenAI-compatible profiles and helpers where they are broadly reusable. - -Do not create one package per provider before the API is proven. Start with built-ins implementing the provider definition contract, then extract providers that have enough special logic or dependency weight to justify it. - -## Dynamic Import Contract - -Native provider package loading should be strict. - -Accept: - -```ts -export default Provider.make({ ... }) -``` - -Optionally accept a named export for CommonJS or package-author convenience: - -```ts -export const provider = Provider.make({ ... }) -``` - -Reject packages that only export arbitrary functions like `createOpenAI`. A bare `model` export is useful for direct users, but the dynamic loader needs the full provider definition so it can validate `id` and select named `apis` uniformly. - -Validation should check: - -- `id` is a non-empty string. -- `model` is a function. -- `apis`, when present, is a record of functions. - -Provider definitions should not receive secrets through global state. OpenCode passes `apiKey` or `auth` material explicitly through model options. - -## Option Mapping - -The OpenCode bridge owns translation from OpenCode/models.dev options into provider model options. - -Provider definitions own provider-specific interpretation. - -For example, OpenCode can pass: - -```ts -{ - providerOptions: { - openrouter: { - usage: true, - reasoning: { effort: "high" }, - }, - }, -} -``` - -The OpenRouter provider decides how that becomes payload fields. Models.dev should not know the wire field names beyond declarative provider option defaults. - -## Security And Operational Policy - -Dynamic native plugins execute code. Treat them like current AI SDK provider packages: - -- Only load packages named by user config, local models.dev metadata, or trusted models.dev metadata. -- Keep package installation in the existing npm cache/install mechanism. -- Do not load native plugin packages for the default native path unless native mode is enabled or the provider is explicitly allowlisted. -- Log provider package, version if available, provider ID, and available model APIs. -- Avoid printing secrets in plugin load failures. - -## Migration Plan - -1. Add `Provider.Definition`, `Provider.ModelOptions`, `Provider.ModelFactory`, and `Provider.make` to `@opencode-ai/llm`. -2. Add built-in provider definitions next to existing helper namespaces. -3. Replace OpenCode's native bridge provider table with a registry lookup against built-in plugins. -4. Keep the AI SDK package compatibility map as a fallback while models.dev metadata catches up. -5. Extend OpenCode's models.dev schemas to parse optional `opencode` metadata. -6. Add dynamic import support for `opencode.npm` behind the existing native feature flag. -7. Add deterministic tests for built-in registry resolution, dynamic plugin loading, validation failures, and AI SDK fallback. -8. Update models.dev to emit native metadata for built-in providers. -9. Dogfood external package loading with one provider package before documenting the contract as stable. -10. Extract heavier providers into subpackages only after the contract survives OpenCode integration. - -## Open Questions - -- Should provider `model` return `Effect.Effect` instead of a synchronous value? Synchronous is simpler and matches current helpers, but Vertex/AWS credential discovery may eventually prefer Effect. -- Should `opencode.api` be a generic hint, or should each provider define its own accepted metadata shape? Generic hints are easier for models.dev, but provider-specific metadata is more type-accurate. -- Should external provider packages depend on `@opencode-ai/llm` as a peer dependency to avoid duplicate adapter registries? Probably yes. -- Should the native path allow custom local `file://` plugin packages the same way the AI SDK path does? Probably yes for development and enterprise providers. - -## Recommendation - -Build the native provider definition contract before adding many more one-off bridge mappings. - -Keep the current bridge as migration glue, but make built-ins implement the same `Provider.Definition` contract intended for third-party packages. That gives OpenCode a clean long-term story: - -- AI SDK metadata keeps powering the existing path. -- Native metadata selects native providers. -- Built-ins and external packages use the same interface. -- Provider-specific behavior lives in code, not in `models.dev` data. -- Third-party providers can plug in without OpenCode guessing export names or copying AI SDK's contract by accident. diff --git a/packages/llm/TOUR.md b/packages/llm/TOUR.md index 1e3593a1f19c..1a126f97f838 100644 --- a/packages/llm/TOUR.md +++ b/packages/llm/TOUR.md @@ -16,7 +16,7 @@ packages/llm/ llm.ts public constructors and runtime helpers adapter/ adapter composition, transport, auth, framing, protocol contracts protocols/ OpenAI, Anthropic, Gemini, Bedrock, and compatible protocols - providers/ model helpers and provider-specific routing metadata + providers/ provider definitions and provider-specific routing metadata tool*.ts typed tool definitions and tool-loop runtime test/ deterministic fixtures, recorded cassettes, and unit coverage script/ package scripts @@ -123,7 +123,7 @@ The runtime pipeline is concentrated in [`src/adapter/client.ts`](./src/adapter/ The important functions are: -- `Adapter.model`, which binds a user-facing model helper to the adapter that can run it. +- `Adapter.model`, which binds a provider model factory to the adapter that can run it. - `LLMClient`, which selects a registered adapter, builds the payload, sends HTTP, and parses the response. - `Adapter.make`, which composes protocol semantics with endpoint, auth, and framing. @@ -485,20 +485,41 @@ Provider family wiring lives here: - Provider profiles and capabilities: [`src/providers/openai-compatible-profile.ts`](./src/providers/openai-compatible-profile.ts) - OpenRouter wrapper with provider-specific options: [`src/providers/openrouter.ts`](./src/providers/openrouter.ts) -## 7.

Existing `Endpoint`, `Auth`, and `Framing` stay separate modules; `Transport` composes them for a runnable movement path rather than replacing them. + +## Type-Safe Transport Interface + +The transport seam should be generic inside the adapter implementation. The registry can erase adapter types, just like it already erases payload types today, but individual transport constructors should keep `Payload`, `Prepared`, and `Frame` connected. + +```ts +export interface TransportContext { + readonly request: LLMRequest +} + +export interface TransportRuntime { + readonly http: RequestExecutor.Interface + readonly webSocket?: WebSocketExecutor.Interface +} + +export interface Transport { + readonly id: string + readonly prepare: ( + payload: Payload, + context: TransportContext, + ) => Effect.Effect + readonly frames: ( + prepared: Prepared, + context: TransportContext, + runtime: TransportRuntime, + ) => Stream.Stream +} +``` + +`Prepared` is transport-private and remains type-safe while implementing the transport: + +```ts +type HttpPrepared = { + readonly request: HttpClientRequest.HttpClientRequest +} + +type OpenAIResponsesWebSocketPrepared = { + readonly url: string + readonly headers: Headers.Headers + readonly message: OpenAIResponsesWebSocketMessage +} +``` + +The adapter keeps the generic relationship through construction: + +```ts +export interface MakeInput { + readonly id: string + readonly protocol: Protocol + readonly transport: Transport +} +``` + +The adapter registry can still erase these generics internally, but that erasure should remain local to `client.ts` as it does today: + +```ts +// local registry erasure only; do not expose this from public adapter modules +// oxlint-disable-next-line typescript-eslint/no-explicit-any +type AnyAdapter = Adapter +``` + +Do not use `unknown` for the internal registry unless TypeScript variance proves it assignable. The type-safety goal is that `Transport` is checked at construction time; registry erasure is an implementation detail after construction. + +## Adapter Runner + +`Adapter.make(...)` should become the generic runner constructor: + +```ts +export function make( + input: MakeInput, +): Adapter { + const decodePayload = ProviderShared.validateWith(Schema.decodeUnknownEffect(input.protocol.payload)) + const decodeChunk = Schema.decodeUnknownEffect(input.protocol.chunk) + + return register({ + id: input.id, + protocol: input.protocol.id, + payloadSchema: input.protocol.payload, + toPayload: input.protocol.toPayload, + prepareTransport: (payload, context) => input.transport.prepare(payload, context), + streamPrepared: (prepared, context, runtime) => + input.transport.frames(prepared, context, runtime).pipe( + Stream.mapEffect((frame) => decodeChunk(frame)), + // same state-machine fold used today by ProviderShared.framed + ), + }) +} +``` + +This preserves the public `LLMClient.prepare`, `LLMClient.stream`, and `LLMClient.generate` shape. `LLMClient.layer` captures a `TransportRuntime` once and passes it to adapters internally, so caller-facing methods remain environment-free. + +`PreparedRequest.payload` remains `unknown` externally, with `PreparedRequestOf` available for callers that know the adapter payload type. The transport-private `Prepared` type should not be exposed in `PreparedRequest` or provider-facing APIs. + +`PreparedRequest.metadata` can record the transport id for debugging: + +```ts +metadata: { transport: "websocket" } +``` + +That is additive and optional. + +## HTTP Transport + +The existing `Adapter.make(...)` input shape should remain available for ordinary adapters by re-expressing it as a helper around `Transport.httpJson(...)`. + +```ts +export const adapter = Adapter.makeHttp({ + id: "openai-responses", + protocol: OpenAIResponses.protocol, + endpoint: Endpoint.baseURL({ default: "https://api.openai.com/v1", path: "/responses" }), + auth: Auth.bearer(), + framing: Framing.sse, +}) +``` + +`makeHttp(...)` should preserve today's adapter author ergonomics and internally build: + +```ts +Transport.httpJson({ endpoint, auth, framing, headers }) +``` + +This keeps the first WebSocket patch small because existing protocol files do not need to change unless they opt into a non-HTTP route. + +## OpenAI Responses WebSocket Transport + +Add a WebSocket adapter route in `src/protocols/openai-responses.ts`: + +```ts +export const websocketAdapter = Adapter.make({ + id: "openai-responses-websocket", + protocol, + transport: Transport.openAIResponsesWebSocket({ + endpoint: endpoint(), + auth: Auth.bearer(), + }), +}) +``` + +The WebSocket transport should: + +1. Reuse the same endpoint renderer as HTTP: default `https://api.openai.com/v1/responses`. +2. Reuse the same `Auth` path as HTTP so model-level `auth` overrides and `OPENAI_API_KEY` fallback continue to work. +3. Convert `https:` to `wss:` and `http:` to `ws:`. +4. Send one JSON message: + +```ts +{ + type: "response.create", + ...payloadWithoutStream, +} +``` + +OpenAI's generated schema notes that `stream` is implicit over WebSocket and should not be sent. + +5. Treat each incoming text WebSocket message as one JSON frame for `OpenAIResponses.protocol.chunk`. +6. Close or interrupt the socket after the protocol observes a terminal chunk. + +The message type should be typed from the existing payload: + +```ts +type OpenAIResponsesWebSocketMessage = Omit & { + readonly type: "response.create" +} +``` + +That type is not enough by itself. The implementation must explicitly omit `stream` at runtime before encoding, and the sent message should be encoded through an Effect Schema JSON codec rather than direct unvalidated `JSON.stringify`. + +## Protocol Terminal Signal + +HTTP SSE streams end naturally. A WebSocket stream may remain open, so the adapter runner needs protocol help to know when one request is complete. + +Add an optional protocol method: + +```ts +export interface Protocol { + readonly terminal?: (chunk: Chunk) => boolean +} +``` + +For OpenAI Responses: + +```ts +terminal: (chunk) => + chunk.type === "response.completed" || + chunk.type === "response.incomplete" || + chunk.type === "response.failed" +``` + +The terminal signal is protocol knowledge. The transport should not need to know OpenAI event names. + +The runner should apply the terminal check after chunk decoding and processing, so the terminal chunk still emits its final `request-finish` or provider error event. + +## Effect Services And Layers + +Follow the package's existing Effect style: `Context.Service` plus `Layer.effect(...)` returning `Service.of(...)`. + +Add a dedicated WebSocket service because socket construction, header support, close handling, and transport-error mapping are runtime concerns: + +```ts +export interface Interface { + readonly open: (input: WebSocketRequest) => Effect.Effect +} + +export class Service extends Context.Service()("@opencode/LLM/WebSocketExecutor") {} +``` + +The service should hide platform differences and expose a package-local shape, not raw `globalThis.WebSocket`: + +```ts +export interface WebSocketRequest { + readonly url: string + readonly headers: Headers.Headers +} + +export interface WebSocketConnection { + readonly sendText: (message: string) => Effect.Effect + readonly messages: Stream.Stream + readonly close: Effect.Effect +} +``` + +Do not make a second constructor service just to model header-capable WebSockets. The deep runtime seam is `WebSocketExecutor.Service`: tests, Bun, Node `ws`, or future platform layers can provide `open(...)` directly. The executor may expose a helper for wrapping an already-created `globalThis.WebSocket`, but adapter code should depend only on `WebSocketExecutor.Service`. + +```ts +export const fromWebSocket: ( + ws: globalThis.WebSocket, + request: WebSocketRequest, +) => Effect.Effect +``` + +Browser WebSocket constructors cannot set arbitrary `Authorization` headers and should not be advertised as supporting OpenAI WebSocket auth unless an alternate auth mechanism exists. + +Layer wiring options: + +```ts +LLMClient.layer // HTTP only, current default +LLMClient.layerWithWebSocket // HTTP + WebSocketExecutor.Service +WebSocketExecutor.Service // exported for explicit app/test wiring +``` + +`LLMClient.layer` should remain enough for all existing adapters. It captures a `TransportRuntime` with `http` only. `LLMClient.layerWithWebSocket` captures both `http` and `webSocket`. If a caller selects `openai-responses-websocket` without the WebSocket-capable layer, the WebSocket transport should fail with a typed transport error that says the selected adapter requires `WebSocketExecutor.Service`. + +## Provider API + +Expose the route explicitly from `src/providers/openai.ts`: + +```ts +export const responsesWebSocket = ( + id: string | ModelID, + options: OpenAIModelInput> = {}, +) => OpenAIResponses.webSocketModel( + withOpenAIOptions(id, { ...options, auth: auth(options) }, { textVerbosity: true }), +) + +export const provider = Provider.make({ + id, + model: responses, + apis: { responses, chat, responsesWebSocket }, +}) +``` + +This makes transport choice visible in the model ref: + +```ts +model.adapter // "openai-responses-websocket" +model.protocol // "openai-responses" +``` + +That mirrors the existing adapter-route versus protocol distinction used by OpenAI-compatible providers. + +## Adapter Author Experience + +HTTP adapter authors should keep the boring path: + +```ts +export const adapter = Adapter.makeHttp({ + id: "provider-chat", + protocol, + endpoint: Endpoint.baseURL({ default: "https://api.provider.test/v1", path: "/chat/completions" }), + framing: Framing.sse, +}) +``` + +Non-HTTP adapter authors should write a transport and keep their prepared type private: + +```ts +type Prepared = { + readonly url: string + readonly headers: Headers.Headers + readonly message: ProviderMessage +} + +const transport: Transport = { + id: "provider-websocket", + prepare: (payload, context) => ..., + frames: (prepared, context, runtime) => ..., +} + +export const adapter = Adapter.make({ + id: "provider-websocket", + protocol, + transport, +}) +``` + +The adapter author chooses a transport frame type. The protocol author chooses a protocol frame/chunk schema. TypeScript keeps those connected through `Adapter.make(...)`. + +## Test Plan + +Add deterministic tests before live recorded tests. + +Transport-level tests: + +- WebSocket executor opens with redacted/auth headers. +- WebSocket executor is provided as the runtime seam, with tests supplying a fake executor instead of raw browser/global WebSocket assumptions. +- WebSocket executor maps open/write/read/close failures into `LLMError`. +- WebSocket transport sends `response.create` and omits `stream`. +- WebSocket transport converts `https` to `wss` and preserves query params. + +Adapter-level tests: + +- `OpenAI.responsesWebSocket(...)` produces `adapter: "openai-responses-websocket"` and `protocol: "openai-responses"`. +- `LLMClient.prepare(...)` returns the same payload shape as HTTP Responses. +- Incoming `response.output_text.delta` emits `text-delta`. +- Incoming function-call argument deltas emit existing tool events. +- Terminal `response.completed` emits one `request-finish` and closes/takes the stream. +- Provider `error` messages map to provider-error or typed transport error consistently with HTTP stream errors. + +Regression tests: + +- Existing HTTP OpenAI Responses tests remain unchanged. +- Existing `RequestExecutor` retry behavior remains HTTP-only. +- `LLMClient.layer` can still run HTTP adapters without WebSocket services. +- Selecting `openai-responses-websocket` with `LLMClient.layer` fails with a clear typed missing-WebSocket-runtime error. + +## Rollout Steps + +1. Add `transport.ts` and `http-transport.ts` while preserving `Adapter.make(...)` or adding `Adapter.makeHttp(...)` as a compatibility helper. Do this only if the existing HTTP path moves behind the same seam in the same patch series. +2. Move the existing HTTP request-building and parsing pipeline behind `Transport.httpJson(...)` with no behavior changes. +3. Add protocol `terminal?` and wire the runner to stop after terminal chunks. +4. Add `adapter/transport/websocket.ts`, with tests using a fake executor layer. +5. Add OpenAI Responses WebSocket transport and adapter route. +6. Add `OpenAI.responsesWebSocket(...)` provider facade and export tests. +7. Add focused deterministic stream tests. +8.

Split the 929-line `schema.ts` into `schema/{ids,options,messages,events,errors}.ts` with an `index.ts` barrel. No consumer changes — the barrel preserves all existing imports. - Add `AuthOptions.bearer(options, envVar)` so providers that follow the apiKey-or-env bearer pattern (openai, xai) collapse their local auth factories to a one-liner. - Replace `...OpenAIChat.protocol` spread with explicit `stream: ...protocol.stream` in openrouter so a new top-level field on OpenAIChat can't silently leak in. --- packages/llm/src/providers/openai.ts | 10 +- packages/llm/src/providers/openrouter.ts | 2 +- packages/llm/src/providers/xai.ts | 10 +- packages/llm/src/route/auth-options.ts | 14 +- packages/llm/src/schema.ts | 929 ----------------------- packages/llm/src/schema/errors.ts | 200 +++++ packages/llm/src/schema/events.ts | 237 ++++++ packages/llm/src/schema/ids.ts | 34 + packages/llm/src/schema/index.ts | 5 + packages/llm/src/schema/messages.ts | 224 ++++++ packages/llm/src/schema/options.ts | 248 ++++++ 11 files changed, 966 insertions(+), 947 deletions(-) delete mode 100644 packages/llm/src/schema.ts create mode 100644 packages/llm/src/schema/errors.ts create mode 100644 packages/llm/src/schema/events.ts create mode 100644 packages/llm/src/schema/ids.ts create mode 100644 packages/llm/src/schema/index.ts create mode 100644 packages/llm/src/schema/messages.ts create mode 100644 packages/llm/src/schema/options.ts diff --git a/packages/llm/src/providers/openai.ts b/packages/llm/src/providers/openai.ts index 7c9ccd065f02..ea101d944d4d 100644 --- a/packages/llm/src/providers/openai.ts +++ b/packages/llm/src/providers/openai.ts @@ -1,5 +1,4 @@ -import { Auth } from "../route/auth" -import type { ProviderAuthOption } from "../route/auth-options" +import { AuthOptions, type ProviderAuthOption } from "../route/auth-options" import type { RouteModelInput } from "../route/client" import { Provider } from "../provider" import { ProviderID, type ModelID } from "../schema" @@ -21,12 +20,7 @@ type OpenAIModelInput = Omit & readonly providerOptions?: OpenAIProviderOptionsInput } -const auth = (options: ProviderAuthOption<"optional">) => { - if ("auth" in options && options.auth) return options.auth - return Auth.optional("apiKey" in options ?

WebSocket open path now also responds to scope abort. - Drop the `RouteContext` / `TransportContext` wrappers; the only field was `request`, so transports and routes now take `LLMRequest` directly. - Tighten registry semantics: registering a duplicate route id throws instead of silently keeping the first. - Bedrock media: dispatch by MIME table so unknown formats fail with a clear error instead of degrading into a malformed document block. - Anthropic Messages: refactor `step` from one long if-chain into named per-event handlers (`onMessageStart`, `onContentBlockStart`, etc.) dispatched from a small top-level switch. Also rename the one-off `anthropicString` accessor to `signatureFromMetadata`. - Executor: consolidate the duplicated sensitive-name regexes into a single `SENSITIVE_NAME_SOURCE` plus named JSON/query field patterns. --- .../llm/src/protocols/anthropic-messages.ts | 173 +++++++++------- .../llm/src/protocols/openai-responses.ts | 133 +++--------- .../llm/src/protocols/utils/bedrock-media.ts | 41 ++-- packages/llm/src/route/client.ts | 54 ++--- packages/llm/src/route/executor.ts | 43 ++-- packages/llm/src/route/index.ts | 5 +- packages/llm/src/route/transport/http.ts | 51 ++--- packages/llm/src/route/transport/index.ts | 10 +- packages/llm/src/route/transport/websocket.ts | 103 +++++++++- packages/llm/test/adapter.test.ts | 44 ++-- .../test/provider/bedrock-converse.test.ts | 2 +- packages/llm/test/recorded-runner.ts | 95 +++++++++ packages/llm/test/recorded-test.ts | 100 ++------- packages/llm/test/recorded-websocket.ts | 193 ++++++++---------- 14 files changed, 554 insertions(+), 493 deletions(-) create mode 100644 packages/llm/test/recorded-runner.ts diff --git a/packages/llm/src/protocols/anthropic-messages.ts b/packages/llm/src/protocols/anthropic-messages.ts index 4be831864177..2f83314b97ff 100644 --- a/packages/llm/src/protocols/anthropic-messages.ts +++ b/packages/llm/src/protocols/anthropic-messages.ts @@ -196,11 +196,10 @@ const cacheControl = (cache: CacheHint | undefined) => cache?.type === "ephemera const anthropicMetadata = (metadata: Record): ProviderMetadata => ({ anthropic: metadata }) -const anthropicString = (metadata: ProviderMetadata | undefined, key: string) => { +const signatureFromMetadata = (metadata: ProviderMetadata | undefined): string | undefined => { const anthropic = metadata?.anthropic if (!ProviderShared.isRecord(anthropic)) return undefined - const value = anthropic[key] - return typeof value === "string" ? value : undefined + return typeof anthropic.signature === "string" ? anthropic.signature : undefined } const lowerTool = (tool: ToolDefinition): AnthropicTool => ({ @@ -269,7 +268,7 @@ const lowerMessages = Effect.fn("AnthropicMessages.lowerMessages")(function* (re continue } if (part.type === "reasoning") { - content.push({ type: "thinking", thinking: part.text, signature: part.encrypted ?? anthropicString(part.providerMetadata, "signature") }) + content.push({ type: "thinking", thinking: part.text, signature: part.encrypted ?? signatureFromMetadata(part.providerMetadata) }) continue } if (part.type === "tool-call") { @@ -412,91 +411,111 @@ const serverToolResultEvent = (block: NonNullable - Effect.gen(function* () { - if (event.type === "message_start") { - const usage = mapUsage(event.message?.usage) - return [usage ? { ...state, usage: mergeUsage(state.usage, usage) } : state, []] as const - } +type StepResult = readonly [ParserState, ReadonlyArray] - if ( - event.type === "content_block_start" && - event.index !== undefined && - (event.content_block?.type === "tool_use" || event.content_block?.type === "server_tool_use") - ) { - return [{ - ...state, - tools: ToolStream.start(state.tools, event.index, { - id: event.content_block.id ??

The route just composes a path onto whatever host the model already carries. Endpoint: - `Endpoint` shrinks to `{ path }`. No more `default`, `baseURL`, or `required` fallback fields. - `Endpoint.path(value)` replaces the old `Endpoint.baseURL({...})` factory. - `Endpoint.render()` is now sync — `${model.baseURL}${path}` plus query params. No fallback chain, no Effect wrapper. ModelRef: - `ModelRef.baseURL: Schema.String` (was optional). Every materialized model carries a host. - `RouteModelInput.baseURL?: string` stays optional so route defaults can supply a canonical URL; routes without a default tighten it. Provider helpers: - Each protocol exports a `DEFAULT_BASE_URL` constant and bakes it into `route.defaults.baseURL`. Provider helpers don't need to set baseURL. - Azure uses a new `AtLeastOne` helper from `auth-options.ts` to require either `resourceName` or `baseURL` at the type level. - Bedrock provider computes baseURL from `region` at construction time. - OpenAI-compatible profiles now have required (not optional) `baseURL` in their type — all 9 already supplied one. - The `defaultBaseURL: string | false` knob on protocol endpoint factories is gone. Effects: - Forgetting baseURL is now caught at compile time (TS) or model construction time (modelWithDefaults runtime check), not request time. - `Endpoint.render` no longer needs Effect wrapping in the transport hot path. --- packages/llm/example/tutorial.ts | 7 +- .../llm/src/protocols/anthropic-messages.ts | 5 +- .../llm/src/protocols/bedrock-converse.ts | 14 ++-- packages/llm/src/protocols/gemini.ts | 9 ++- packages/llm/src/protocols/openai-chat.ts | 19 ++---- .../src/protocols/openai-compatible-chat.ts | 13 ++-- .../llm/src/protocols/openai-responses.ts | 19 ++---- packages/llm/src/providers/amazon-bedrock.ts | 12 +++- packages/llm/src/providers/anthropic.ts | 2 +- packages/llm/src/providers/azure.ts | 36 +++++----- packages/llm/src/providers/github-copilot.ts | 8 ++- packages/llm/src/providers/google.ts | 2 +- .../providers/openai-compatible-profile.ts | 2 +- .../llm/src/providers/openai-compatible.ts | 8 +-- packages/llm/src/providers/openai.ts | 3 +- packages/llm/src/providers/openrouter.ts | 5 +- packages/llm/src/providers/xai.ts | 5 +- packages/llm/src/route/auth-options.ts | 9 +++ packages/llm/src/route/client.ts | 23 ++++++- packages/llm/src/route/endpoint.ts | 56 ++++++---------- packages/llm/src/route/transport/http.ts | 2 +- packages/llm/src/schema/options.ts | 2 +- packages/llm/test/adapter.test.ts | 9 +-- packages/llm/test/auth-options.types.ts | 2 + packages/llm/test/auth.test.ts | 2 +- packages/llm/test/endpoint.test.ts | 66 +++++++------------ packages/llm/test/llm.test.ts | 11 ++-- packages/llm/test/schema.test.ts | 1 + packages/opencode/src/provider/llm-bridge.ts | 9 ++- .../test/session/llm-native-events.test.ts | 2 +- 30 files changed, 167 insertions(+), 196 deletions(-) diff --git a/packages/llm/example/tutorial.ts b/packages/llm/example/tutorial.ts index 794e178ffb93..9741ac4d93da 100644 --- a/packages/llm/example/tutorial.ts +++ b/packages/llm/example/tutorial.ts @@ -157,17 +157,14 @@ const FakeProtocol = Protocol.make({ const FakeAdapter = Route.make({ id: "fake-echo", protocol: FakeProtocol, - endpoint: Endpoint.baseURL({ - default: "https://fake.local", - path: "/v1/echo", - }), + endpoint: Endpoint.path("/v1/echo"), auth: Auth.passthrough, framing: Framing.sse, }) // A provider module exports a Provider definition.

Owns request lowering, the payload schema, the chunk schema, and the streaming chunk-to-event state machine. `Route.make(...)` validates and JSON-encodes the payload from the payload schema and decodes frames with the chunk schema. Examples: `OpenAIChat.protocol`, `OpenAIResponses.protocol`, `AnthropicMessages.protocol`, `Gemini.protocol`, `BedrockConverse.protocol`. -- **`Endpoint`** (`src/route/endpoint.ts`) — URL construction. Receives the request and the validated payload so it can read `model.id`, `model.baseURL`, `model.queryParams`, and any payload field that influences the URL (e.g. Bedrock's `modelId` segment). Reach for `Endpoint.baseURL({ default, path })` before hand-rolling a URL. -- **`Auth`** (`src/route/auth.ts`) — per-request transport authentication. Adapters read `model.apiKey` at request time via `Auth.bearer` (the `Route.make` default; sets `Authorization: Bearer `) or `Auth.apiKeyHeader(name)` for providers that use a custom header (Anthropic `x-api-key`, Gemini `x-goog-api-key`). Adapters that need per-request signing (Bedrock SigV4, future Vertex IAM, Azure AAD) implement `Auth` as a function that signs the body and merges signed headers into the result. +- **`Protocol`** (`src/route/protocol.ts`) — semantic API contract. Owns request body construction (`body.from`), the body schema (`body.schema`), the streaming-event schema (`stream.event`), and the event-to-`LLMEvent` state machine (`stream.step`). `Route.make(...)` validates and JSON-encodes the body from `body.schema` and decodes frames with `stream.event`. Examples: `OpenAIChat.protocol`, `OpenAIResponses.protocol`, `AnthropicMessages.protocol`, `Gemini.protocol`, `BedrockConverse.protocol`. +- **`Endpoint`** (`src/route/endpoint.ts`) — path construction. The host always lives on `model.baseURL`; the endpoint just supplies the path. `Endpoint.path("/chat/completions")` is the common case; pass a function for paths that embed the model id or a body field (e.g. `Endpoint.path(({ body }) => `/model/${body.modelId}/converse-stream`)`). +- **`Auth`** (`src/route/auth.ts`) — per-request transport authentication. Routes read `model.apiKey` at request time via `Auth.bearer` (the default; sets `Authorization: Bearer `) or `Auth.apiKeyHeader(name)` for providers that use a custom header (Anthropic `x-api-key`, Gemini `x-goog-api-key`).

"openai-responses", - protocol, - endpoint: input.endpoint ?? endpoint(...), - auth: input.auth, - framing: Framing.sse, - }) -``` - -It exists only because route values are not yet easy to copy and modify. - -The target is immutable derivation on a single `Route` value: - -```ts -export const openAIResponses = Route.make({ - id: "openai-responses", - provider: "openai", - protocol: OpenAIResponses.protocol, - transport: Transport.httpJson({ - endpoint: Endpoint.baseURL({ path: "/responses", base: { type: "default", url: DEFAULT_BASE_URL } }), - auth: Auth.bearer(), - framing: Framing.sse, - }), - defaults: { - capabilities: capabilities({ tools: { calls: true, streamingInput: true } }), - }, -}) - -export const azureResponses = openAIResponses.with({ - id: "azure-openai-responses", - provider: "azure", - transport: openAIResponses.transport.with({ - endpoint: Endpoint.requiredBaseURL({ - path: "/responses", - message: "Azure OpenAI requires resourceName or baseURL", - }), - auth: azureAuth, - }), -}) -``` - -This preserves reuse without hiding variant behavior behind protocol-specific factory parameters, and without a second route concept. - -### One Route Concept - -There is one `Route` concept. No `RouteTemplate`, no separate base/derived split. - -Every route used by a provider helper should have a provider. Reuse happens by immutably deriving one provider route from another: - -```ts -export const responses = Route.make({ - id: "openai-responses", - provider: "openai", - protocol: OpenAIResponses.protocol, - transport: Transport.httpJson({ - endpoint: Endpoint.baseURL({ path: "/responses", base: { type: "default", url: DEFAULT_BASE_URL } }), - auth: Auth.bearer(), - framing: Framing.sse, - }), - defaults: { - capabilities: capabilities({ tools: { calls: true, streamingInput: true } }), - }, -}) - -export const azureResponses = responses.with({ - id: "azure-openai-responses", - provider: "azure", - transport: responses.transport.with({ - endpoint: Endpoint.requiredBaseURL({ - path: "/responses", - message: "Azure OpenAI requires resourceName or baseURL", - }), - auth: azureAuth, - }), -}) -``` - -The risk is inherited provider/default leakage. Mitigate that with API shape: - -- `.with(...)` is immutable and returns a new route. -- deriving a provider route should require `id` and `provider` when either changes. -- duplicate route ids should fail or be explicit. -- provider is route identity; capabilities/limits/generation are route defaults and remain overridable by model options. -- `.model(...)` uses the route defaults and returns a concrete `ModelRef` with `route` set. - -### Typed Transport Derivation - -Transport replacement should not force callers to restate unrelated internals. - -This is awkward: - -```ts -const azureResponses = responses.with({ - id: "azure-openai-responses", - provider: "azure", - transport: Transport.httpJson({ - endpoint: Endpoint.requiredBaseURL(...), - auth: azureAuth, - framing: Framing.sse, // only repeated because the whole transport was rebuilt - }), -}) -``` - -Transport values should be immutable and copyable too: - -```ts -const azureResponses = responses.with({ - id: "azure-openai-responses", - provider: "azure", - transport: responses.transport.with({ - endpoint: Endpoint.requiredBaseURL(...), - auth: azureAuth, - }), -}) -``` - -For authoring ergonomics, route can expose typed transport-specific helpers: - -```ts -const azureResponses = responses.withHttpJson({ - id: "azure-openai-responses", - provider: "azure", - endpoint: Endpoint.requiredBaseURL(...), - auth: azureAuth, -}) -``` - -`withHttpJson(...)` should only exist on HTTP JSON routes. WebSocket routes get WebSocket-specific derivation: - -```ts -const customResponsesWs = responsesWebSocket.withWebSocket({ - id: "custom-openai-responses-websocket", - endpoint: customEndpoint, - auth: customAuth, -}) -``` - -This gives a useful type-level distinction without adding a second route concept: - -```ts -Route -``` - -The route knows its transport type, so derivation can offer the right partial override API for that transport. - -### Coherent Target - -The smallest coherent target that addresses all these smells: - -- Replace protocol-specific `makeRoute(...)` factories with immutable route derivation. -- Replace `defaultBaseURL: false` / `endpointRequired` with explicit endpoint policies. -- Treat provider/capabilities/limits/generation as route defaults that can be overridden by model options. -- Keep one `Route` concept; reuse happens through immutable `.with(...)` derivation. -- Make transports immutable/copyable so provider variants can override endpoint/auth without restating framing or unrelated transport internals. -- Let provider modules export provider-bound routes and model helpers as the primary API. - -## Registry Semantics - -Routes are registered by route id, not by provider/model id. - -```ts -routeRegistry.set("openai-responses", responsesHttpRoute) -routeRegistry.set("openai-responses-websocket", responsesWebSocketRoute) -``` - -`ModelRef` carries the selected route id: - -```ts -OpenAI.responses("gpt-4.1-mini", { transport: "websocket" }) -// ModelRef { provider: "openai", id: "gpt-4.1-mini", route: "openai-responses-websocket" } -``` - -Execution resolves the route: - -```ts -const route = routeRegistry.get(request.model.route) -``` - -Importing a provider module should register the routes that its exported helpers can select. For `OpenAI.responses(...)`, that means both the HTTP and WebSocket Responses routes are available once the OpenAI provider module is imported. If bundle size or tree-shaking later require finer control, route registration can become explicit, but selector sugar must never produce a `ModelRef` for a route that was not registered by the same import path. - -## Prepared Requests And Metadata - -Prepared requests should expose concrete route details. - -Prepared output should be concrete and derived from route resolution: - -```ts -PreparedRequest { - route: "openai-responses-websocket" - protocol: "openai-responses" - transport: "websocket-json" -} -``` - -`PreparedRequest.protocol` is acceptable because prepare has already resolved the route. It is derived output metadata, not duplicated model configuration. - -## OpenCode Config Constraint - -OpenCode can expose user-friendly provider options while still resolving to a concrete route before execution. - -Example config: - -```json -{ - "provider": { - "openai": { - "options": { - "transport": "websocket" - } - } - } -} -``` - -The package-level constraint is simple: transport selection must be string-serializable and route-agnostic enough for config files. - -Bridge behavior can be: - -```ts -const model = - options.transport === "websocket" - ? OpenAI.responses(id, { ...options, transport: "websocket" }) - : OpenAI.responses(id, options) -``` - -or equivalently: - -```ts -const model = OpenAI.responses(id, options) -``` - -if `OpenAI.responses` itself owns route selection. - -The bridge should not pass transport selection through `LLM.request.http`. - -## Migration Plan - -### Step 1: Rename Adapter To Route Publicly - -Do this as one coordinated schema/API change, not as a partial internal alias. - -Rename: - -- `Adapter` export -> `Route` -- `AdapterShape` -> `RouteShape` -- `AdapterContext` -> `RouteContext` -- `AnyAdapter` -> `AnyRoute` -- `routeRegistry` -> `routeRegistry` -- `model.adapter` -> `model.route` -- `PreparedRequest.adapter` -> `PreparedRequest.route` -- error reason fields from `adapter` to `route` where they identify the runnable route - -Remove: - -- `model.protocol` - -Derive protocol from route metadata after route resolution. If missing-route errors need extra context, route id plus provider/model id are sufficient. - -Temporary compatibility aliases are acceptable only if they are clearly deprecated and not used in new code/docs. - -### Step 2: Move `.model(...)` Onto The Route - -Current implementation can keep `Route.model(route, defaults)` while the rename lands. The cleaner target is `route.model(id, options)` directly on the provider-bound route — provider, capabilities, limits, and generation already live on the route, and `.with(...)` covers any per-derivation overrides. - -```ts -const model = openAIResponses.model("gpt-4.1-mini", { apiKey }) -``` - -Do not move this to `Provider.model(...)`. A provider is the catalog namespace; routes own route-backed model-ref construction. - -### Step 3: Keep Runtime Behavior Stable - -Keep current runtime behavior: - -- `Route.make(...)` supports explicit transports. -- `OpenAI.responses(...)` returns HTTP SSE. -- `OpenAI.responsesWebSocket(...)` returns WebSocket. -- Both routes share `OpenAIResponses.protocol`. - -### Step 4: Add Transport Selector Sugar - -Add `transport?: "http" | "websocket"` to OpenAI Responses model helper options. - -Implementation rule: - -- select route inside `OpenAI.responses(...)` -- return a concrete `ModelRef` -- do not defer selection to execution - -Keep `OpenAI.responsesWebSocket(...)` permanently as the canonical discoverable alias. The option-style form is ergonomic sugar; the alias is load-bearing for code search and explicitness. - -## Open Questions - -- Is `Route` the best name, or is `ModelRoute` clearer because routes are selected by models? -- Should route families become a named helper type, or remain local provider-helper implementation detail? - -## Recommendation - -Adopt this mental model: - -- `Provider`: catalog and user helper namespace. -- `ModelRef`: concrete selected model plus selected route id. -- `Protocol`: semantic lowering/parsing. -- `Transport`: mechanics for moving frames. -- `Route`: concrete runnable protocol + transport composition. - -Commit to the public `Route -> Route` rename if we pursue this plan. Keep route selection at model construction time. Let provider helpers expose ergonomic transport choices, but always resolve them into concrete route ids before requests execute. Store the selected route id on `ModelRef`; derive protocol from the route registry. diff --git a/packages/llm/DESIGN.websocket-transport.md b/packages/llm/DESIGN.websocket-transport.md deleted file mode 100644 index 4d7398bbcfef..000000000000 --- a/packages/llm/DESIGN.websocket-transport.md +++ /dev/null @@ -1,440 +0,0 @@ -# WebSocket Transport Proposal - -## Status - -Proposal: keep OpenAI WebSocket support as a transport-level route route that reuses the existing OpenAI Responses protocol. - -The implementation should deepen the route seam without making protocol authors think about sockets and without turning WebSocket into a provider option hidden inside an existing HTTP route. - -## Goal - -Support OpenAI's WebSocket Responses backend in `@opencode-ai/llm` while preserving the current protocol architecture: - -- `Protocol` owns provider semantics: request lowering, payload schema, stream chunk schema, and chunk-to-`LLMEvent` parsing. -- `Transport` owns movement: HTTP request/response, SSE framing, WebSocket message flow, and platform execution. -- `Route` composes one protocol with one transport route. -- Effect services provide runtime capabilities such as HTTP execution and WebSocket construction. - -The key result should be an explicit model constructor: - -```ts -const model = OpenAI.responsesWebSocket("gpt-4.1-mini", { apiKey }) -``` - -Existing constructors keep their current behavior: - -```ts -OpenAI.model("gpt-4.1-mini") // OpenAI Responses over HTTP SSE -OpenAI.responses("gpt-4.1-mini") // OpenAI Responses over HTTP SSE -OpenAI.chat("gpt-4o-mini") // OpenAI Chat over HTTP SSE -``` - -## Current State - -`src/route/client.ts` currently combines two separate ideas in one module: - -- route registry, request option resolution, payload validation, and response collection -- HTTP-specific execution details through `toHttp(...)`, `RequestExecutor.Service`, and `route.parse(response, context)` - -The current runtime path is: - -```text -LLMRequest - -> protocol.toPayload - -> protocol.payload validation - -> route.toHttp - -> RequestExecutor.execute - -> route.parse(HttpClientResponse) - -> Framing - -> protocol.chunk - -> protocol.process - -> LLMEvent -``` - -That path is correct for HTTP providers, but it bakes in the assumption that every route produces an `HttpClientRequest` and consumes an `HttpClientResponse`. - -Effect's OpenAI implementation does not fork the language model protocol for WebSocket mode.

The Public Runtime Is Small - -The public `LLM` namespace lives in [`src/llm.ts`](./src/llm.ts). - -Read these pieces first: - -- `LLM.make` builds the default model-bound runtime. -- `LLM.layer` provides that runtime as an Effect service. -- `LLM.generate` and `LLM.stream` are thin service calls. -- `LLM.request` turns ergonomic input into canonical schema classes. -- `LLM.stream({ request, tools })` can expose and execute typed tools. - -The canonical data model is in [`src/schema.ts`](./src/schema.ts). That file defines the runtime shapes that every provider lowers from or emits back to: `ModelRef`, `LLMRequest`, `Message`, `ContentPart`, `LLMEvent`, `Usage`, and the typed error classes. - -The key design choice is that the public request model stays provider-neutral. Common controls live in `generation`, provider-native controls live in `providerOptions.`, and raw serializable HTTP patches live in `http`. Provider-specific wire bodies are not represented in `LLMRequest`; they live in protocol-local payload schemas. - -## 3. Name The Big Pieces - -Before following one request through the runtime, name the main concepts: - -- `LLMRequest`: the canonical provider-neutral request. This is what callers build and what protocols read. -- `ModelRef`: the selected model plus routing metadata. `model.route` chooses the runnable route route; `route.protocol` records the wire protocol semantics. -- `generation`: provider-neutral call controls. Model values are defaults; request values override them. -- `providerOptions`: namespaced provider-native knobs. Model values are defaults; request values override by provider namespace. -- `http`: last-resort serializable overlays for final body, headers, and query params. -- `Protocol`: the wire-format brain. It converts `LLMRequest` into a provider-native payload and parses provider-native stream chunks back into `LLMEvent`s. -- `Route`: the runnable deployment. It combines one `Protocol` with an `Endpoint`, `Auth`, `Framing`, and headers. -- `RequestExecutor`: the transport boundary. It sends an `HttpClientRequest` and returns an `HttpClientResponse`. -- `LLMEvent`: the normalized stream output. Every provider eventually emits the same event vocabulary. - -The most important distinction is route route versus protocol implementation: - -```ts -const model: ModelRef = OpenAICompatible.deepseek.model("deepseek-chat") - -model.route // "openai-compatible-chat" — which runnable route to use -route.protocol // "openai-chat" — which wire protocol it speaks -``` - -Most routes have the same value for both fields. OpenAI-compatible Chat is the useful exception: it routes through the generic compatible route while reusing the OpenAI Chat wire protocol. - -## 4. Follow One Request Through The Pipeline - -The runtime pipeline is concentrated in [`src/route/client.ts`](./src/route/client.ts). - -The important functions are: - -- `Route.model`, which binds a provider model factory to the route that can run it. -- `LLMClient`, which selects a registered route, builds the payload, sends HTTP, and parses the response. -- `Route.make`, which composes protocol semantics with endpoint, auth, and framing. - -At runtime, the flow is easier to read as a sequence of values. There are two levels to keep separate: - -- The main request path: caller input becomes a provider HTTP request, then normalized events. -- The parser zoom-in: `route.parse(...)` hides response framing, chunk decoding, and stream state. - -```text -RequestInput - -> LLMRequest - -> provider Payload - -> HttpClientRequest - -> HttpClientResponse - -> Stream - -> LLMResponse - -Zoom into route.parse(...): - -HttpClientResponse.stream - -> Framing - -> Frame - -> protocol.chunk - -> Chunk - -> protocol.process(State, Chunk) - -> LLMEvent[] - -> Stream -``` - -The snippet below is pseudo-code.

That makes request-shape tests cheap and makes demos easy because you can show exactly what would be sent.

Protocols Are The Provider-Native Semantics - -The protocol abstraction is defined in [`src/route/protocol.ts`](./src/route/protocol.ts). - -A protocol owns the parts that are intrinsic to an API family: - -- `payload`: Effect Schema for the provider-native JSON request body. -- `toPayload`: convert common `LLMRequest` into that provider payload. -- `chunk`: Effect Schema for one framed response item. -- `initial`: initial parser state for a response stream. -- `process`: chunk-by-chunk state machine that emits common `LLMEvent`s. -- `onHalt`: optional final flush when the stream ends. - -The type shape is deliberately four-part: request payload, framed response item, decoded chunk, and parser state. - -```ts -interface Protocol { - readonly id: ProtocolID - readonly payload: Schema.Codec - readonly toPayload: (request: LLMRequest) => Effect.Effect - readonly chunk: Schema.Codec - readonly initial: () => State - readonly process: ( - state: State, - chunk: Chunk, - ) => Effect.Effect], ProviderChunkError> - readonly onHalt?: (state: State) => ReadonlyArray -} -``` - -Read those generics as the same parser zoom-in from Section 4: - -- `Payload`: the provider-native JSON body after request conversion and validation. -- `Frame`: one response unit after byte framing, such as an SSE `data:` string or a Bedrock event-stream object. -- `Chunk`: the provider-native stream chunk after Schema decoding one frame. -- `State`: the accumulator needed to turn a sequence of chunks into common events. - -The main protocol implementations are: - -- OpenAI Chat Completions: [`src/protocols/openai-chat.ts`](./src/protocols/openai-chat.ts) -- OpenAI Responses: [`src/protocols/openai-responses.ts`](./src/protocols/openai-responses.ts) -- Anthropic Messages: [`src/protocols/anthropic-messages.ts`](./src/protocols/anthropic-messages.ts) -- Gemini GenerateContent: [`src/protocols/gemini.ts`](./src/protocols/gemini.ts) -- Bedrock Converse: [`src/protocols/bedrock-converse.ts`](./src/protocols/bedrock-converse.ts) - -The protocol files are sectioned the same way: - -```ts -Public Model Input -Request Payload Schema -Request To Payload -Stream Parsing -Protocol And Route -Model Helper -``` - -That layout keeps the same story in each file: wire payload, request lowering, stream parsing, and route assembly. - -## 6. Route Composition Is Where The Reuse Shows Up - -The route composition rule is: - -```ts -Route = Protocol + Endpoint + Auth + Framing -``` - -```text - +-------------------+ - | Protocol | request lowering + stream parsing - +-------------------+ - | -+----------+ +---------v---------+ +------+ +---------+ -| Endpoint | --> | Route | <-- | Auth | <-- | Framing | -+----------+ +-------------------+ +------+ +---------+ - URL runnable route headers bytes -> frames -``` - -The pieces live in these files: - -- Protocol contract: [`src/route/protocol.ts`](./src/route/protocol.ts) -- Route constructor: [`src/route/client.ts`](./src/route/client.ts) -- Endpoint rendering: [`src/route/endpoint.ts`](./src/route/endpoint.ts) -- Auth strategies: [`src/route/auth.ts`](./src/route/auth.ts) -- Stream framing: [`src/route/framing.ts`](./src/route/framing.ts) - -The runnable route erases the response internals after composition. Callers only need a payload type plus a normalized parser: - -```ts -interface Route { - readonly id: string - readonly protocol: ProtocolID - readonly payloadSchema: Schema.Codec - readonly toPayload: (request: LLMRequest) => Effect.Effect - readonly toHttp: ( - payload: Payload, - context: HttpContext, - ) => Effect.Effect - readonly parse: ( - response: HttpClientResponse.HttpClientResponse, - context: HttpContext, - ) => Stream.Stream -} -``` - -`id` is the route route used for model lookup. `protocol` is the wire protocol implementation id. Most routes use matching values, but OpenAI-compatible Chat is intentionally different: the route route is `openai-compatible-chat`, while the reused wire protocol is `openai-chat`. - -`Endpoint` receives both the canonical request and the validated provider payload, so dynamic paths can read either side: - -```ts -interface EndpointInput { - readonly request: LLMRequest - readonly payload: Payload -} - -type EndpointPart = string | ((input: EndpointInput) => string) - -interface Endpoint { - readonly baseURL?: EndpointPart - readonly path: EndpointPart - readonly required?: string -} -``` - -`Auth` is a per-request header function. It can be a simple API-key merge or a full body-signing strategy: - -```ts -type Auth = (input: AuthInput) => Effect.Effect, LLMError> - -interface AuthInput { - readonly request: LLMRequest - readonly method: "POST" | "GET" - readonly url: string - readonly body: string - readonly headers: Record -} -``` - -`Framing` is the transport-to-protocol seam. It does not know about JSON payload schemas or common events: - -```ts -interface Framing { - readonly id: string - readonly frame: (bytes: Stream.Stream) => Stream.Stream -} -``` - -OpenAI Chat is the base case. It defines a full protocol and route in [`src/protocols/openai-chat.ts`](./src/protocols/openai-chat.ts). - -OpenAI-compatible Chat is the code-reuse showcase in [`src/protocols/openai-compatible-chat.ts`](./src/protocols/openai-compatible-chat.ts): - -```ts -export const route = Route.make({ - id: "openai-compatible-chat", - protocol: OpenAIChat.protocol, - endpoint: Endpoint.baseURL({ - path: "/chat/completions", - required: "OpenAI-compatible Chat requires a baseURL", - }), - framing: Framing.sse, -}) -``` - -That route reuses `OpenAIChat.protocol` end-to-end. It changes the deployment axes: route route id, endpoint, and provider identity. - -The payoff is that providers like DeepSeek, TogetherAI, Cerebras, Baseten, Fireworks, DeepInfra, Groq, and OpenRouter can share the same Chat protocol instead of copying a 300-line route. - -Provider family wiring lives here: - -- Generic OpenAI-compatible provider helper: [`src/providers/openai-compatible.ts`](./src/providers/openai-compatible.ts) -- Provider profiles and capabilities: [`src/providers/openai-compatible-profile.ts`](./src/providers/openai-compatible-profile.ts) -- OpenRouter wrapper with provider-specific options: [`src/providers/openrouter.ts`](./src/providers/openrouter.ts) - -## 7. Provider Definitions Keep Call Sites Boring - -The provider modules exported from [`src/providers/index.ts`](./src/providers/index.ts) are thin use-site APIs built around [`Provider.make`](./src/provider.ts). - -`Provider.make(...)` is the public contract for provider packages: - -```ts -export const provider = Provider.make({ - id: ProviderID.make("openai"), - model: responses, - apis: { responses, chat }, -}) - -export const model = provider.model -export const apis = provider.apis -``` - -The shape is intentionally small: - -- `id`: branded provider id used for routing and option namespaces. -- `model`: default model factory, usually the provider's recommended API. -- `apis`: optional named API-specific factories, for providers where one model id can route through different native APIs. - -Built-in providers export namespace modules such as `OpenAI`, `Azure`, and `OpenRouter`. Those modules expose `provider` plus ergonomic aliases like `model`, `chat`, `responses`, or `apis` so internal call sites stay direct. External provider packages should make their default export the `Provider.make(...)` result and may also export named aliases for convenience. - -Examples: - -- `OpenAI.model` defaults to Responses, while `OpenAI.apis.chat` and `OpenAI.chat` construct a Chat model in [`src/providers/openai.ts`](./src/providers/openai.ts). -- `Anthropic.model` constructs a Messages model in [`src/providers/anthropic.ts`](./src/providers/anthropic.ts). -- `Google.model` constructs a Gemini model in [`src/providers/google.ts`](./src/providers/google.ts). -- `AmazonBedrock.model` constructs a Bedrock Converse model with credentials in [`src/providers/amazon-bedrock.ts`](./src/providers/amazon-bedrock.ts). -- `OpenAICompatible.deepseek.model` constructs a named OpenAI-compatible deployment model in [`src/providers/openai-compatible.ts`](./src/providers/openai-compatible.ts). -- `OpenRouter.model` constructs an OpenAI-compatible Chat model with OpenRouter options in [`src/providers/openrouter.ts`](./src/providers/openrouter.ts). - -Provider definitions should usually not contain stream parsing, JSON decoding, or protocol details. They set provider identity, defaults, capabilities, deployment options, auth defaults, and model-bound routes. Keep lower-level route arrays as separate advanced exports; they are implementation details, not fields on `Provider.make(...)`. - -## 8. Provider Options Lower In Providers Or Protocols - -Provider-specific knobs should live at the closest concrete owner: - -- Provider facades attach typed defaults to `ModelRef.providerOptions`, `ModelRef.generation`, and `ModelRef.http`. -- Calls can pass the same option shape on `LLM.request(...)` or directly to `LLM.generate(...)` / `LLM.stream(...)`. -- The client resolves model defaults plus request overrides before protocol lowering. Later request values win. -- Protocols lower `generation` and their own provider namespace into provider-native payload fields. -- Thin provider wrappers, such as OpenRouter, can extend a reused protocol payload when the provider has extra native fields. - -The public split is: - -```ts -LLM.request({ - model, - prompt: "Think briefly.", - generation: { - maxTokens: 1024, - temperature: 0, - topP: 0.9, - }, - providerOptions: { - openai: { reasoningEffort: "high" }, - anthropic: { thinking: { type: "enabled", budgetTokens: 4096 } }, - gemini: { thinkingConfig: { thinkingBudget: 4096, includeThoughts: true } }, - openrouter: { reasoning: { effort: "high" } }, - }, - http: { - body: { raw_provider_field: true }, - headers: { "x-provider-experiment": "1" }, - query: { debug: "1" }, - }, -}) -``` - -Use `http` only as a serializable escape hatch. If a field is stable and provider-owned, promote it into `providerOptions.`. - -Do not grow common request schemas just to fit one provider. Prefer `generation` for genuinely common sampling/output controls, typed `providerOptions` for provider behavior, and protocol/provider-local lowering for native wire details. - -## 9. Tools Are Typed End To End - -The public tutorial shows typed tools in [`example/tutorial.ts`](./example/tutorial.ts). The implementation is in [`src/tool.ts`](./src/tool.ts) and [`src/tool-runtime.ts`](./src/tool-runtime.ts). - -What is worth showing: - -- Tool definitions use Effect Schema for inputs and success values: [`src/tool.ts`](./src/tool.ts) -- Tool runtime streams model output, dispatches tool calls, validates results, and loops: [`src/tool-runtime.ts`](./src/tool-runtime.ts) -- Unknown tools, invalid input, and handler failures become model-visible tool errors: [`test/tool-runtime.test.ts`](./test/tool-runtime.test.ts) -- Provider-executed tools pass through without client dispatch: [`src/tool-runtime.ts`](./src/tool-runtime.ts) - -The common event model is what makes this work across providers. Providers emit `tool-input-delta`, `tool-call`, `tool-result`, and `request-finish` events; the runtime consumes those events and decides whether another model round is needed. - -Streamed tool-call assembly is shared by [`src/protocols/utils/tool-stream.ts`](./src/protocols/utils/tool-stream.ts). Protocols still own provider-native chunk interpretation, finish reason mapping, and usage mapping; the helper only starts pending tool calls, appends argument JSON deltas, emits `tool-input-delta`, and finalizes parsed `tool-call` events. - -## 10. Stream Parser Examples - -Examples worth reading: - -- [`src/protocols/openai-chat.ts`](./src/protocols/openai-chat.ts) accumulates streamed tool JSON by numeric index and finalizes tool calls at `finish_reason`. -- [`src/protocols/openai-responses.ts`](./src/protocols/openai-responses.ts) handles item lifecycle events and hosted provider-executed tool items. -- [`src/protocols/anthropic-messages.ts`](./src/protocols/anthropic-messages.ts) merges usage from `message_start` and `message_delta`, and supports server tools. -- [`src/protocols/gemini.ts`](./src/protocols/gemini.ts) converts Gemini parts into text, reasoning, and tool-call events. -- [`src/protocols/bedrock-converse.ts`](./src/protocols/bedrock-converse.ts) parses AWS event-stream frames and waits for metadata to emit finish with usage. - -This is where provider APIs differ the most, behind the same normalized `LLMEvent` stream. - -## 11. Deterministic Tests Cover The Parser Edge Cases - -Before live recordings, the package uses deterministic in-memory HTTP layers. - -Start with [`test/lib/http.ts`](./test/lib/http.ts): - -- `fixedResponse` returns one deterministic provider response body. -- `dynamicResponse` inspects the outgoing request and builds a response. -- `truncatedStream` simulates mid-stream transport failure. -- `scriptedResponses` drives multi-round tool loops with a sequence of responses. - -SSE helpers live in [`test/lib/sse.ts`](./test/lib/sse.ts). OpenAI chunk helpers live in [`test/lib/openai-chunks.ts`](./test/lib/openai-chunks.ts). - -Good tests to read: - -- [`test/provider/openai-chat.test.ts`](./test/provider/openai-chat.test.ts) covers request payloads, stream text, usage, tool-call streaming, malformed chunks, and HTTP errors. -- [`test/provider/openai-responses.test.ts`](./test/provider/openai-responses.test.ts) covers Responses item lifecycle, hosted tools, and provider errors. -- [`test/provider/anthropic-messages.test.ts`](./test/provider/anthropic-messages.test.ts) covers message blocks, reasoning, server tools, and usage merging. -- [`test/provider/gemini.test.ts`](./test/provider/gemini.test.ts) covers media input, schema conversion, reasoning, and finish reasons. -- [`test/provider/bedrock-converse.test.ts`](./test/provider/bedrock-converse.test.ts) covers binary event stream decoding, SigV4 auth boundaries, and Bedrock tool deltas. -- [`test/tool-runtime.test.ts`](./test/tool-runtime.test.ts) covers tool loop behavior without live model calls. - -These tests are fast because they never call a provider. They validate request bodies and parser behavior directly. - -## 12. The Cassette Recorder Is The Testing Story - -Recorded tests are the coolest part of the safety net. - -The wrapper is [`test/recorded-test.ts`](./test/recorded-test.ts). It builds on `@opencode-ai/http-recorder` and gives each live test a cassette name, metadata, filters, and credential gates. - -Recorded test files: - -- OpenAI Chat basic and tool flows: [`test/provider/openai-chat.recorded.test.ts`](./test/provider/openai-chat.recorded.test.ts) -- OpenAI Chat full tool loop: [`test/provider/openai-chat-tool-loop.recorded.test.ts`](./test/provider/openai-chat-tool-loop.recorded.test.ts) -- OpenAI Responses: [`test/provider/openai-responses.recorded.test.ts`](./test/provider/openai-responses.recorded.test.ts) -- Anthropic Messages: [`test/provider/anthropic-messages.recorded.test.ts`](./test/provider/anthropic-messages.recorded.test.ts) -- Gemini: [`test/provider/gemini.recorded.test.ts`](./test/provider/gemini.recorded.test.ts) -- OpenAI-compatible families: [`test/provider/openai-compatible-chat.recorded.test.ts`](./test/provider/openai-compatible-chat.recorded.test.ts) -- Bedrock Converse recorded cases: [`test/provider/bedrock-converse.test.ts`](./test/provider/bedrock-converse.test.ts) - -The shared recorded scenarios are in [`test/recorded-scenarios.ts`](./test/recorded-scenarios.ts).

Missing cassettes are skipped unless you explicitly record. - -Common commands from `packages/llm`: - -```sh -bun run test -bun run test test/provider/openai-chat.test.ts -bun run test test/provider/openai-chat.recorded.test.ts -RECORDED_PROVIDER=openai bun run test -RECORDED_PREFIX=openai-chat bun run test -RECORDED_TEST="streams text" bun run test -``` - -Record intentionally: - -```sh -RECORD=true OPENAI_API_KEY=... bun run test test/provider/openai-chat.recorded.test.ts -``` - -Recorded filters are implemented in [`test/recorded-test.ts`](./test/recorded-test.ts): - -- `RECORDED_PREFIX` matches cassette groups such as `openai-chat`. -- `RECORDED_PROVIDER` matches metadata tags such as `provider:openai`. -- `RECORDED_TAGS` requires tags such as `tool` or `provider:togetherai`. -- `RECORDED_TEST` matches by test name, kebab id, or cassette path. - -The setup script is [`script/setup-recording-env.ts`](./script/setup-recording-env.ts). It helps populate `.env.local`, checks which provider credentials are present, and can verify recommended recording providers. - -The cost report script is [`script/recording-cost-report.ts`](./script/recording-cost-report.ts). It walks cassette files, extracts usage from provider response bodies, looks up pricing from `models.dev`, and prints estimated recording costs. - -## 14. Why This Design Is Nice - -The package gets several useful properties from this shape: - -- Simple use site from `LLM.generate`, provider model helpers, and `LLM.request` constructors. -- Provider code reuse from separating `Protocol`, `Endpoint`, `Auth`, and `Framing`. -- Native wire visibility because payload and chunk schemas stay close to lowering/parsing code. -- Safe provider quirks because provider-specific payload fields stay in provider/protocol code instead of the common request schema. -- Common UI/runtime events because every provider parser emits `LLMEvent`s. -- Tool-loop portability because tool orchestration consumes common tool events instead of provider-specific streams. -- Fast parser tests from `fixedResponse`, `dynamicResponse`, and `scriptedResponses`. -- Real integration confidence because HTTP cassettes replay actual provider wire data. - -## 15. Suggested Reading Paths - -For a user-facing demo: - -1. Open [`example/tutorial.ts`](./example/tutorial.ts). -2. Run `OPENAI_API_KEY=... bun example/tutorial.ts` from `packages/llm`. -3. Skim [`src/llm.ts`](./src/llm.ts) to see how little the public API does. -4. Open [`test/provider/openai-chat.test.ts`](./test/provider/openai-chat.test.ts) to show deterministic parser tests. -5.

From c4c60e76aef462c4e893632c45e59d23c7512fda Mon Sep 17 00:00:00 2001 From: Kit Langton Date: Thu, 7 May 2026 13:15:16 -0400 Subject: [PATCH 179/196] refactor(llm): polish openai-responses hosted tools and body schemas Three small cleanups in the OpenAI Responses protocol: - Unify `HOSTED_TOOL_NAMES` + `hostedToolInput` into one `HOSTED_TOOLS` record per tool: `{ name, input: (item) => unknown }`. Adding a new hosted tool is now a single entry instead of two parallel switches that must stay in sync. - Tighten `isHostedToolItem`'s narrowing to include the `type` field, so callers know they're dealing with a known hosted-tool shape (not just "has an id"). Drives a cleaner `hostedToolEvents` signature. - Split the body schema into a shared `OpenAIResponsesCoreFields` record used by both the HTTP body (adds `stream: true`) and the WebSocket `response.create` message (adds `type`). Removes the destructure-and- strip dance at schema definition time. Runtime conversion in `webSocketMessage` still strips `stream` because OpenAI's WebSocket API doesn't expect it on the wire. Plus a tiny fix in bedrock-converse.ts: explicit `Route.model` type argument so the mapInput overload selects properly (was inferring to the narrower `RouteModelInput`). --- .../llm/src/protocols/bedrock-converse.ts | 8 +- .../llm/src/protocols/openai-responses.ts | 88 ++++++++++--------- 2 files changed, 52 insertions(+), 44 deletions(-) diff --git a/packages/llm/src/protocols/bedrock-converse.ts b/packages/llm/src/protocols/bedrock-converse.ts index 89ce4ed9a51b..2664ebf2289a 100644 --- a/packages/llm/src/protocols/bedrock-converse.ts +++ b/packages/llm/src/protocols/bedrock-converse.ts @@ -103,7 +103,7 @@ type BedrockAssistantBlock = Schema.Schema.Type const BedrockMessage = Schema.Union([ Schema.Struct({ role: Schema.Literal("user"), content: Schema.Array(BedrockUserBlock) }), Schema.Struct({ role: Schema.Literal("assistant"), content: Schema.Array(BedrockAssistantBlock) }), -]) +]).pipe(Schema.toTaggedUnion("role")) type BedrockMessage = Schema.Schema.Type const BedrockSystemBlock = Schema.Union([BedrockTextBlock, BedrockCache.CachePointBlock]) @@ -212,8 +212,6 @@ const BedrockEvent = Schema.Struct({ }) type BedrockEvent = Schema.Schema.Type -const invalid = ProviderShared.invalidRequest - // ============================================================================= // Request Lowering // ============================================================================= @@ -502,7 +500,9 @@ export const route = Route.make({ // the provider helper from credentials) and the validated modelId in the // path.

Introduce `Provider.getModelHandle(model): { kind: "ai-sdk", model: LanguageModelV3 } | { kind: "native", ref: ModelRef }`. AI SDK plumbing moves into `provider/sdk-resolver.ts` (new file). `BUNDLED_PROVIDERS` moves there. +2. **`provider/error.ts`** — opencode-owned `ProviderError` shape `{ status, message, isRetryable, providerID, responseBody }`. Adapter constructors `fromAPICallError(e)` and `fromLLMError(e: LLMError)`. Removes `APICallError` import from `acp/agent.ts` and most of `provider/error.ts`. +3. **`session/message-v2.ts`** — add `toLLMMessagesEffect` parallel to `toModelMessagesEffect`. Both produced from the same `MessageV2.WithParts[]`. Reuse `session/llm-native.ts` lowering. `ModelMessage` storage shapes (`session.ts:7`) become opencode-owned types. +4. **`session/prompt.ts:resolveTools`** — `Tool.Def` is the canonical tool type. Convert `Tool.Def → AI SDK Tool` lazily inside the AI SDK adapter, not eagerly here. Removes `tool` / `jsonSchema` / `asSchema` imports. +5. **`mcp/index.ts`** — add MCP → `Tool.Def` lowering alongside `dynamicTool`. Once both shapes exist, native gate can keep MCP tools. +6. **`agent/agent.ts:generateObject/streamObject`** — keep on AI SDK for now (structured output isn't on `@opencode-ai/llm` yet); isolate to `LLM.generateObject(input, schema)` Service method so the AI SDK call site is in one place. + +### Phase B — Service-level swap + +Rewrite `session/llm.ts` so the backend is selected once, at layer construction. + +1. Keep `Interface.stream: (input: StreamInput) => Stream.Stream` as the public surface (already opencode-owned). +2. Split `live` into two layers: + - `Service.aiSdkLayer` — current `prepare/run` extracted, wraps `streamText` + GitLab/OpenAI-OAuth quirks + monkey-patching. + - `Service.nativeLayer` — current `runNative` extracted, calls `llmClient.stream` via `LLMNativeTools.runWithTools`. Translates events with `LLMNativeEvents.mapper`. +3. `defaultLayer` selects based on a single `Config.experimental?.llmBackend ?? "ai-sdk"`. **One decision point. No per-request gate.** +4. The `prepare` function is **shared infrastructure**, not AI-SDK-specific. Lift to `session/llm-prepare.ts`. Both backends consume the resulting `PreparedStream`. + +### Phase C — Native parity + +What `@opencode-ai/llm` needs: + +- **Drop the `NATIVE_ROUTES` allowlist**. Add per-route stabilization tests. Order: anthropic-messages (done) → bedrock-converse → openai-responses → openai-chat / openai-compatible-chat → gemini → openrouter-chat. +- **Provider options pass-through**. `LLMRequest` carries opaque per-request `providerOptions`; each protocol lowers what it knows. Or move all known options (reasoning effort, prompt cache key, text verbosity, OpenRouter usage/reasoning) onto `LLM.ModelRef` (mostly done in `llm-bridge.ts`) so per-request options become unnecessary. +- **Retry support** in `RequestExecutor` subsuming `streamText({ maxRetries })`. +- **OpenTelemetry tracing** in `RequestExecutor`, gated by the same config flag. +- **MCP tool support**. Either teach MCP to emit `Tool.Def`, or teach `LLMNativeTools.runWithTools` to dispatch raw AI SDK tools (it already does — `tools: Record`). +- **Structured output**. Either port `generateObject` semantics onto `@opencode-ai/llm`, or keep AI SDK as the structured-output fallback indefinitely. +- **GitLab workflow provider**. Custom WebSocket transport with server-side tool execution. Write a `@opencode-ai/llm` route + transport for it (the existing `WebSocketTransport.json` precedent applies). + +What opencode-side adapter still needs: + +- `experimental_repairToolCall` lowercase fixup → middleware in the native path. +- `_noop` stub tool injection for LiteLLM/Copilot proxies → either move to `@opencode-ai/llm/providers/openai-compatible` profile, or keep in `prepare`. +- OpenAI OAuth `instructions` quirk → encode on the OpenAI provider in `@opencode-ai/llm`. + +### Phase D — Flag-driven rollout + +- Default `ai-sdk`. Internal/CI runs `native`. +- Per-provider opt-in: `Config.experimental.llmBackend.providers = ["anthropic", "bedrock"]` so we can flip Anthropic to native while leaving openai-compatible on AI SDK. +- Telemetry compares finish reasons, token usage, latency, error rates per session. +- Soak each provider until the comparison is boring. + +### Phase E — Delete the AI SDK + +Once native covers all routes + structured output: + +1. Delete `provider/sdk/copilot/*` — replaced by `@opencode-ai/llm/providers/github-copilot`. +2. Shrink `provider/transform.ts` to opencode-policy bits only (max output tokens, temperature defaults, topK). The provider-specific message rewriting lives in protocol lowering inside `@opencode-ai/llm`. +3. Delete `BUNDLED_PROVIDERS` from `provider/provider.ts`. `getLanguage` removed. +4. Delete `session/llm.ts:run` and the `streamText` call. Keep `stream` and `prepare`. +5. Remove `ai`, `@ai-sdk/*`, `@openrouter/ai-sdk-provider`, `gitlab-ai-provider`, `venice-ai-sdk-provider` from `package.json`. +6. Convert `Event = streamText.fullStream` element type to a named `LLM.SessionEvent` schema. + +## Suggested execution order + +1. **Now** — lift `prepare` into a shared module; make `LLM.Service` interface fully opencode-typed (Phase A.1, A.2, B.1–B.2). Low risk, no behavior change. +2. **Next** — drop `NATIVE_ROUTES` allowlist; flip stabilization tests on per-route in `@opencode-ai/llm`. Add per-provider native opt-in flag (Phase B.3, D partial). +3. **Then** — MCP + structured output + retry/OTel parity (Phase C). These unblock most real sessions. +4. **Then** — GitLab workflow + Copilot. These eliminate the largest forks. +5. **Finally** — flip default, soak, delete AI SDK (Phase E). + +## Key files to touch first + +- `packages/opencode/src/session/llm.ts` — split `live` into two layers; extract `prepare`. +- `packages/opencode/src/provider/provider.ts` — split AI SDK plumbing into `provider/sdk-resolver.ts`; narrow `Service.Interface`. +- `packages/opencode/src/provider/error.ts` — opencode-owned `ProviderError` shape. +- `packages/opencode/src/session/message-v2.ts` — add `toLLMMessagesEffect`; eliminate `@ai-sdk/*` branches. +- `packages/opencode/src/session/prompt.ts` — `Tool.Def` as canonical, not AI SDK `tool()`. +- `packages/opencode/src/session/llm-native.ts` and `llm-native-events.ts` — already clean, become *the* path. +- `packages/opencode/src/provider/llm-bridge.ts` — extend with anything currently in `ProviderTransform.providerOptions` that doesn't already have a `ProviderOptions` mapping. +- `packages/llm/src/providers/*.ts` — ensure each provider exposes the per-request options that `provider/transform.ts:providerOptions` produces. + +## Risks and open questions + +- **Telemetry parity.** Today AI SDK emits OTel spans for every model call. Native path has no equivalent. We need parity before flag-flipping or rollout is blind. +- **Token usage normalization.** Each protocol's `mapUsage` produces an `LLM.Usage`; AI SDK produces `LanguageModelUsage`. The shapes are similar but not identical (cache write tokens, reasoning tokens). Audit before flipping. +- **Provider-executed tools.** Anthropic `web_search`/`code_execution`/`web_fetch` and OpenAI Responses hosted tools work end-to-end on the native path. Verify on a recorded scenario per provider before promoting. +- **Tool.Def vs AI SDK `Tool`.** The decision to canonicalize on `Tool.Def` ripples through `prompt.ts`, `mcp/index.ts`, `agent/agent.ts`. Keep both shapes alive during Phase A; choose the cutover point deliberately. +- **`session/message-v2.ts` is huge.** 1221 lines of conversion logic. The `toLLMMessagesEffect` addition is non-trivial; plan a dedicated PR. +- **GitLab workflow.** It's a custom WebSocket protocol with custom tool execution / approval flow. Re-implementing it as a `@opencode-ai/llm` route is its own design exercise. +- **Structured output.** `generateObject` in `agent/agent.ts` may be the longest-lived AI SDK call site if we don't add structured-output support to `@opencode-ai/llm` first.

It's the canonical shape for everything *except* the AI SDK adapter. + +New flow: + +- `resolveTools` returns `Record`. No AI SDK imports. +- `mcp/index.ts` emits `Tool.Def` directly. (`dynamicTool` only needed by the AI SDK adapter.) +- `session/backends/ai-sdk.ts` (Phase 4) converts `Tool.Def → AITool` lazily before calling `streamText`. +- `session/backends/native.ts` already speaks `Tool.Def` — no conversion needed. + +The `Tool.Def → AITool` conversion is small: `tool({ description, parameters: jsonSchema(toolDef.inputSchema), execute: toolDef.execute })`. It's the only place `tool()` and `jsonSchema()` get imported. + +#### 2c — `LLMUsage` and `ProviderMetadata`-the-opencode-type + +Today: `session/session.ts` imports `LanguageModelUsage` and `ProviderMetadata` from `ai`. `getUsage(input)` reads `input.usage.inputTokens`, `outputTokens`, `inputTokenDetails.cacheReadTokens`, etc., and reads provider-specific fields from `metadata["anthropic"]["cacheCreationInputTokens"]`. + +The `LLMUsage` shape in `@opencode-ai/llm` (`packages/llm/src/schema/events.ts`) already covers the cases (inputTokens, outputTokens, reasoningTokens, cacheReadInputTokens, cacheWriteInputTokens, totalTokens, native). + +New flow: + +```ts +// packages/opencode/src/session/session.ts +import { type Usage as LLMUsage, type ProviderMetadata } from "@opencode-ai/llm" + +export const getUsage = (input: { model: Provider.Model; usage: LLMUsage; metadata?: ProviderMetadata }) => { ... } +``` + +`ProviderMetadata` from `@opencode-ai/llm/schema/ids.ts` is `Record>` — same shape, opencode-owned. + +The AI SDK adapter (Phase 4) constructs `LLMUsage` from `LanguageModelUsage` once, just before yielding `step-finish`. Today's `getUsage` already does that math; we move it to the adapter. + +#### 2d — `MessageV2.toLLMMessagesEffect` parallel to `toModelMessagesEffect` + +Today: `session/message-v2.ts` is 1221 lines. The biggest function is `toModelMessagesEffect(input): Effect>` which converts `WithParts[]` to AI SDK `ModelMessage[]`. It branches on `model.api.npm` for cache markers, file-URL handling, etc. + +`session/llm-native.ts` does the same conversion to `LLM.Message[]` (the `@opencode-ai/llm` shape). + +Phase 2d: keep both alive in parallel. Don't try to merge them yet. The AI SDK adapter (Phase 4) calls `toModelMessagesEffect`; the native adapter calls `toLLMMessagesEffect`. + +The key win is that `MessageV2.WithParts` (opencode's stored shape) is the source of truth in both directions. Nothing above this layer cares which target shape is produced. + +#### 2e — `LLM.generateObject(input, schema)` for structured output + +Today: `agent/agent.ts` imports `generateObject` and `streamObject` from `ai` directly. Used to generate agent config (one-shot structured output, not part of `LLM.Service.stream`). + +`@opencode-ai/llm` doesn't have `generateObject` yet. Strategy: keep AI SDK as the structured-output backend until we add it to `@opencode-ai/llm`, but isolate the call site behind an opencode-owned method: + +```ts +// packages/opencode/src/session/llm.ts +LLM.Service.generateObject(input: GenerateObjectInput, schema: Schema.Schema): Effect +``` + +`agent/agent.ts` calls `LLM.Service.generateObject(...)`.

Each phase is shippable, no behavior change unless explicitly noted. - -## Today - -- `provider/provider.ts` — `Provider.Service.getLanguage(model): LanguageModelV3`. Returns the AI SDK's executable runtime model. `BUNDLED_PROVIDERS` dynamically imports each `@ai-sdk/` package. -- `session/llm.ts` — `LLM.Service.stream(input) → Stream`. The only file that calls `streamText` / `wrapLanguageModel`. Has a gated `runNative` path that uses `@opencode-ai/llm` end-to-end (via `session/llm-native.ts`, `llm-native-events.ts`, `llm-native-tools.ts`, `provider/llm-bridge.ts`).

Tiny surface change, makes the rest of the migration possible. - -Today `getLanguage` returns `LanguageModelV3` (an AI SDK runtime object).

Existing `getLanguage` keeps working; new code consumes `getModelHandle`. The union is the migration vehicle — it's deliberately ugly so it's obvious it's temporary. Once AI SDK is gone, the union collapses to `{ ref: ModelRef }`. - -Steps: - -1. Add `getModelHandle` to `Provider.Service` (parallel to `getLanguage`). The native arm calls into `provider/llm-bridge.ts:toModelRef`. The AI SDK arm wraps `getLanguage`. -2. Move AI SDK plumbing (`BUNDLED_PROVIDERS`, dynamic imports) to a new `provider/sdk-resolver.ts`. `provider/provider.ts` consumes it. -3.

Cache-write fallbacks (e.g. `metadata?.["anthropic"]?.["cacheCreationInputTokens"]`) move into the adapter where they belong. - -#### 2d — `MessageV2.toLLMMessagesEffect` parallel to `toModelMessagesEffect` - -Both functions run from the same `MessageV2.WithParts[]` source. Phase 2d adds the new one without touching the old one. - -Before: - -```ts -// session/message-v2.ts (today) -import { convertToModelMessages, type ModelMessage } from "ai" - -export const toModelMessagesEffect = (input: { - messages: ReadonlyArray - model: Provider.Model -}): Effect> => Effect.gen(function* () { - // ~700 lines of provider-specific conversion, branching on model.api.npm -}) -``` - -After (additive — both functions exist in parallel): - -```ts -// session/message-v2.ts -import { convertToModelMessages, type ModelMessage } from "ai" -import { type Message as LLMMessage } from "@opencode-ai/llm" -import { LLMNative } from "./llm-native" - -// Existing function unchanged -export const toModelMessagesEffect = ... - -// New function — delegates to llm-native.ts which already does the lowering -export const toLLMMessagesEffect = (input: { - messages: ReadonlyArray - model: Provider.Model -}): Effect> => - LLMNative.lowerMessages({ messages: input.messages, model: input.model }) -``` - -`session/backends/ai-sdk.ts` calls `toModelMessagesEffect`. `session/backends/native.ts` calls `toLLMMessagesEffect`. Phase 4 wires them up; Phase 2d just makes the new function exist. - -The two paths can be merged later — a single `toCanonicalMessages` that produces an internal opencode shape, with `toAISDKMessages` and `toLLMMessages` as final-mile conversions. Out of scope for Phase 2. - -#### 2e — `LLM.Service.generateObject(input, schema)` for structured output - -`agent/agent.ts` currently imports `generateObject`/`streamObject` directly. It's the only AI SDK call site outside `session/llm.ts`'s `run`. - -Before: - -```ts -// agent/agent.ts -import { generateObject, streamObject, type ModelMessage } from "ai" - -export const generate = (input: AgentGenerateInput) => - Effect.gen(function* () { - const model = yield* Provider.getLanguage(input.model) // returns LanguageModelV3 - const result = yield* Effect.tryPromise(() => - generateObject({ - model, - schema: AgentConfigSchema, - messages: [...] as ModelMessage[], - }), - ) - return result.object - }) -``` - -After: - -```ts -// session/llm.ts — new Service method -export interface LLM { - readonly stream: ... - readonly generateObject: (input: GenerateObjectInput, schema: Schema.Schema) => Effect -} - -// session/backends/ai-sdk.ts — actual generateObject lives here -import { generateObject } from "ai" - -export const generateObjectViaAISDK = (input: GenerateObjectInput, schema: Schema.Schema) => - Effect.gen(function* () { - const handle = yield* Provider.getModelHandle(input.model) - if (handle.kind !== "ai-sdk") return yield* Effect.fail(...) // phase 5 swaps this for native impl - const result = yield* Effect.tryPromise(() => - generateObject({ model: handle.language, schema: toJSONSchema(schema), messages: ... }), - ) - return result.object - }) - -// agent/agent.ts — no AI SDK imports -import { LLM } from "@/session/llm" - -export const generate = (input: AgentGenerateInput) => - LLM.Service.generateObject(input, AgentConfigSchema) -``` - -Pulls the last AI SDK import out of `agent/agent.ts`. Whether the native backend implements `generateObject` (Phase 5) or keeps delegating to AI SDK indefinitely is a separate decision. - -#### 2b — `Tool.Def` as the canonical tool type - -Today: `session/prompt.ts:resolveTools` imports `tool`, `jsonSchema`, `asSchema`, `ToolExecutionOptions`, `Tool as AITool` from `ai` and builds a `Record` for `streamText`. `mcp/index.ts` imports `dynamicTool` and emits AI-SDK-shaped tools. `session/llm-native-tools.ts` invokes the AI SDK `tool.execute(...)` at the leaves (the native dispatcher still calls AI SDK tools). - -opencode already has `Tool.Def` (`packages/opencode/src/tool/tool.ts`) which is the existing internal definition. It's the canonical shape for everything *except* the AI SDK adapter. - -New flow: - -- `resolveTools` returns `Record`. No AI SDK imports. -- `mcp/index.ts` emits `Tool.Def` directly. (`dynamicTool` only needed by the AI SDK adapter.) -- `session/backends/ai-sdk.ts` (Phase 4) converts `Tool.Def → AITool` lazily before calling `streamText`. -- `session/backends/native.ts` already speaks `Tool.Def` — no conversion needed. - -The `Tool.Def → AITool` conversion is small: `tool({ description, parameters: jsonSchema(toolDef.inputSchema), execute: toolDef.execute })`. It's the only place `tool()` and `jsonSchema()` get imported. - -#### 2c — `LLMUsage` and `ProviderMetadata`-the-opencode-type - -Today: `session/session.ts` imports `LanguageModelUsage` and `ProviderMetadata` from `ai`. `getUsage(input)` reads `input.usage.inputTokens`, `outputTokens`, `inputTokenDetails.cacheReadTokens`, etc., and reads provider-specific fields from `metadata["anthropic"]["cacheCreationInputTokens"]`. - -The `LLMUsage` shape in `@opencode-ai/llm` (`packages/llm/src/schema/events.ts`) already covers the cases (inputTokens, outputTokens, reasoningTokens, cacheReadInputTokens, cacheWriteInputTokens, totalTokens, native). - -New flow: - -```ts -// packages/opencode/src/session/session.ts -import { type Usage as LLMUsage, type ProviderMetadata } from "@opencode-ai/llm" - -export const getUsage = (input: { model: Provider.Model; usage: LLMUsage; metadata?: ProviderMetadata }) => { ... } -``` - -`ProviderMetadata` from `@opencode-ai/llm/schema/ids.ts` is `Record>` — same shape, opencode-owned. - -The AI SDK adapter (Phase 4) constructs `LLMUsage` from `LanguageModelUsage` once, just before yielding `step-finish`. Today's `getUsage` already does that math; we move it to the adapter. - -#### 2d — `MessageV2.toLLMMessagesEffect` parallel to `toModelMessagesEffect` - -Today: `session/message-v2.ts` is 1221 lines. The biggest function is `toModelMessagesEffect(input): Effect>` which converts `WithParts[]` to AI SDK `ModelMessage[]`. It branches on `model.api.npm` for cache markers, file-URL handling, etc. - -`session/llm-native.ts` does the same conversion to `LLM.Message[]` (the `@opencode-ai/llm` shape). - -Phase 2d: keep both alive in parallel. Don't try to merge them yet. The AI SDK adapter (Phase 4) calls `toModelMessagesEffect`; the native adapter calls `toLLMMessagesEffect`. - -The key win is that `MessageV2.WithParts` (opencode's stored shape) is the source of truth in both directions. Nothing above this layer cares which target shape is produced. - -#### 2e — `LLM.generateObject(input, schema)` for structured output - -Today: `agent/agent.ts` imports `generateObject` and `streamObject` from `ai` directly. Used to generate agent config (one-shot structured output, not part of `LLM.Service.stream`). - -`@opencode-ai/llm` doesn't have `generateObject` yet. Strategy: keep AI SDK as the structured-output backend until we add it to `@opencode-ai/llm`, but isolate the call site behind an opencode-owned method: - -```ts -// packages/opencode/src/session/llm.ts -LLM.Service.generateObject(input: GenerateObjectInput, schema: Schema.Schema): Effect -``` - -`agent/agent.ts` calls `LLM.Service.generateObject(...)`. Inside, the AI SDK `generateObject` call lives in `session/backends/ai-sdk.ts`. The native backend either delegates to AI SDK or implements it (Phase 5 decision). - -Pulls the only AI SDK import out of `agent/agent.ts`. - -#### Order within Phase 2 - -Roughly leaf-to-root so each step's tests are self-contained: - -1. **2a (ProviderError)** — small, isolated, no downstream churn. -2. **2c (LLMUsage / ProviderMetadata)** — cosmetic types-only swap in session.ts. -3. **2b (Tool.Def canonical)** — moderate; `resolveTools` is the biggest call site. -4. **2d (toLLMMessagesEffect)** — additive; `toModelMessagesEffect` keeps working. -5. **2e (LLM.generateObject)** — last; adds a Service method, isolates the agent.ts call site. - -### Phase 3 — Lift `prepare()` out of `session/llm.ts` - -`prepare()` is backend-agnostic: system messages, plugin hooks (`chat.params`, `chat.headers`), tool resolution, header building. Today it's mixed in with `run()` (the AI SDK call). Lift to `session/llm-prepare.ts`. Both backends consume the result. - -Pure refactor. No behavior change. - -### Phase 4 — Split `LLM.Service.live` into two layers - -``` -session/backends/ai-sdk.ts — current run() extracted -session/backends/native.ts — current runNative() extracted, no gate -``` - -`LLM.Service.layer` selects based on a single config flag at construction: - -```ts -Config.experimental?.llmBackend ?? "ai-sdk" // "ai-sdk" | "native" -``` - -One decision point. No per-request gate. The decision is global. Drop `NATIVE_ROUTES` allowlist and `runNative`'s gate conditions; they were guards for a half-built path that's about to be all-or-nothing. - -### Phase 5 — Native parity - -What `@opencode-ai/llm` needs before native can be the default: - -- Per-route stabilization tests (anthropic-messages → bedrock-converse → openai-responses → openai-chat / openai-compatible-chat → gemini → openrouter-chat). -- Provider options pass-through. Either accept opaque per-request `providerOptions` in `LLMRequest` and lower per protocol, or move all known options (reasoning effort, prompt cache key, text verbosity, OpenRouter usage/reasoning) onto `LLM.ModelRef`. -- Retry support in `RequestExecutor` subsuming `streamText({ maxRetries })`. -- OpenTelemetry tracing in `RequestExecutor`, gated by config. -- MCP tool dispatch on the native path (likely already works — `runWithTools` accepts AI SDK `Tool`). -- Structured output: either port `generateObject` semantics, or keep AI SDK as the structured-output fallback indefinitely. -- GitLab workflow provider: custom WebSocket transport with server-side tool execution. Write a `@opencode-ai/llm` route + transport (the existing `WebSocketTransport.json` precedent applies). - -What opencode-side adapter still needs: - -- `experimental_repairToolCall` lowercase fixup → middleware in the native path. -- `_noop` stub tool injection for LiteLLM/Copilot proxies → either to `@opencode-ai/llm/providers/openai-compatible` profile or kept in `prepare`. -- OpenAI OAuth `instructions` quirk → encode on the OpenAI provider in `@opencode-ai/llm`. - -### Phase 6 — Per-provider rollout - -- Default flag stays `ai-sdk`. Internal/CI runs `native`. -- Per-provider opt-in: `Config.experimental.llmBackend.providers = ["anthropic", "bedrock"]`. -- Telemetry compares finish reasons, token usage, latency, error rates. Soak each provider until comparison is boring. - -### Phase 7 — Delete the AI SDK - -1. Delete `provider/sdk/copilot/*` — replaced by `@opencode-ai/llm/providers/github-copilot`. -2. Shrink `provider/transform.ts` to opencode-policy bits only (max output tokens, temperature defaults, topK). Provider-specific message rewriting lives in protocol lowering inside `@opencode-ai/llm`. -3. Delete `BUNDLED_PROVIDERS` and `provider/sdk-resolver.ts`. `getLanguage` removed. -4. Collapse the `ModelHandle` discriminated union to `{ ref: ModelRef }` (or simplify back to a metadata-only Provider). -5. Delete `session/llm.ts:run` (the `streamText` call) and `session/backends/ai-sdk.ts`. `LLM.Service` is the native path. -6. Remove `ai`, `@ai-sdk/*`, `@openrouter/ai-sdk-provider`, `gitlab-ai-provider`, `venice-ai-sdk-provider` from `package.json`. -7. Convert `Event = streamText.fullStream` element type to a named `LLM.SessionEvent` schema. - -## Order to execute - -1. Phase 1 (model handle) — small, mechanical, unlocks everything. -2. Phase 2 (decouple types) — most of the actual work, but each step is a clean PR. -3. Phase 3 (lift prepare) — small, pure refactor. -4. Phase 4 (split layers) — flips the architecture even if native isn't ready yet. -5. Phase 5 (parity) — the real grind. Item-by-item. -6. Phase 6 (rollout) — per-provider, telemetry-gated. -7. Phase 7 (delete) — celebratory. - -## Risks - -- **Telemetry parity.** AI SDK emits OTel spans for every model call. Native path has no equivalent. Block flag-flipping until parity. -- **Token usage normalization.** `LLM.Usage` and `LanguageModelUsage` are similar but not identical (cache write tokens, reasoning tokens). Audit before flipping. -- **Provider-executed tools.** Anthropic `web_search`/`code_execution`/`web_fetch` and OpenAI Responses hosted tools work end-to-end on the native path. Verify per provider on a recorded scenario before promoting. -- **`Tool.Def` cutover.** Canonicalizing on `Tool.Def` ripples through `prompt.ts`, `mcp/index.ts`, `agent/agent.ts`. Keep both shapes alive during Phase 2; choose the cutover point deliberately. -- **GitLab workflow.** Custom WebSocket protocol with custom tool execution / approval flow. Re-implementing it as a `@opencode-ai/llm` route is its own design exercise. -- **Structured output.** `agent/agent.ts:generateObject` may be the longest-lived AI SDK call site if we don't add structured-output support to `@opencode-ai/llm` first. diff --git a/packages/opencode/package.json b/packages/opencode/package.json index 37713a1b3b65..8c5aa3499823 100644 --- a/packages/opencode/package.json +++ b/packages/opencode/package.json @@ -110,7 +110,6 @@ "@octokit/graphql": "9.0.2", "@octokit/rest": "catalog:", "@openauthjs/openauth": "catalog:", - "@opencode-ai/llm": "workspace:*", "@opencode-ai/plugin": "workspace:*", "@opencode-ai/script": "workspace:*", "@opencode-ai/sdk": "workspace:*", diff --git a/packages/opencode/src/provider/llm-bridge.ts b/packages/opencode/src/provider/llm-bridge.ts deleted file mode 100644 index 4626b99be998..000000000000 --- a/packages/opencode/src/provider/llm-bridge.ts +++ /dev/null @@ -1,173 +0,0 @@ -import { - LLM, - ReasoningEffort as ReasoningEffortSchema, - TextVerbosity as TextVerbositySchema, - mergeProviderOptions, - type ModelRef, - type ProviderOptions, -} from "@opencode-ai/llm" -import { AmazonBedrock, Anthropic, Azure, GitHubCopilot, Google, OpenAI, OpenAICompatible, OpenRouter, XAI } from "@opencode-ai/llm/providers" -import * as OpenAICompatibleProfiles from "@opencode-ai/llm/providers/openai-compatible-profile" -import { Option, Schema } from "effect" -import { isRecord } from "@/util/record" -import type * as Provider from "./provider" - -type Input = { - readonly provider: Provider.Info - readonly model: Provider.Model -} - -const decodeReasoningEffort = Schema.decodeUnknownOption(ReasoningEffortSchema) -const decodeTextVerbosity = Schema.decodeUnknownOption(TextVerbositySchema) - -const stringOption = (options: Record, key: string) => { - const value = options[key] - if (typeof value === "string" && value.trim() !== "") return value - return undefined -} - -const recordOption = (options: Record, key: string): Record => { - const value = options[key] - if (!isRecord(value)) return {} - return Object.fromEntries(Object.entries(value).filter((entry): entry is [string, string] => typeof entry[1] === "string")) -} - -const configuredProviderOptions = (options: Record): ProviderOptions | undefined => { - if (!isRecord(options.providerOptions)) return undefined - const result = Object.fromEntries( - Object.entries(options.providerOptions).filter((entry): entry is [string, Record] => isRecord(entry[1])), - ) - return Object.keys(result).length === 0 ? undefined : result -} - -const openAIOptions = ( - options: Record, - configured: ProviderOptions | undefined = configuredProviderOptions(options), -): ProviderOptions | undefined => { - const openai = Object.fromEntries(Object.entries({ - store: typeof options.store === "boolean" ? options.store : undefined, - promptCacheKey: stringOption(options, "promptCacheKey"), - reasoningEffort: Option.getOrUndefined(decodeReasoningEffort(options.reasoningEffort)), - reasoningSummary: options.reasoningSummary === "auto" ?
