docs: drop release-candidate framing ahead of the 4.5 GA (#4100)

ericallam · web-flow · commit 4536eded9eed · 2026-07-02T11:11:12.000+01:00
Removes the release-candidate framing from the docs for the 4.5 GA: the
`@rc` install caveats on the `skills` CLI command, and the AI Agents and
Prompts release-candidate banner (a shared snippet used across the
ai-chat and prompts pages) plus the `&gt;=4.5.0-rc.0` compatibility pin in
the AI reference.

 ## Overview
 
 Custom actions let the frontend send structured commands (undo, rollback, edit, regenerate) that modify the conversation state. **Actions are not turns**: they fire `hydrateMessages` (if set) and `onAction` only. No turn lifecycle hooks (`onTurnStart` / `prepareMessages` / `onBeforeTurnComplete` / `onTurnComplete`), no `run()`, no turn-counter increment. The trace span is named `chat action`.

 Long conversations accumulate tokens across turns. Eventually the context window fills up, causing errors or degraded responses. Compaction solves this by automatically summarizing the conversation when token usage exceeds a threshold, then using that summary as the context for future turns.

 **A custom agent is a task you register with `chat.customAgent()` and drive yourself — either with the managed turn iterator from `chat.createSession()`, or with a fully hand-rolled loop over the raw chat primitives.** You give up `chat.agent()`'s lifecycle hooks and automatic continuation recovery; you gain inline control over every turn, and (at the lowest level) full control over the stream conversion.

 `chat.agent` errors fall into four layers, each with different recovery semantics. The default behavior is **conversation-preserving**: a thrown error in a hook or `run()` does not kill the chat. The current turn ends with an error chunk, and the agent waits for the user's next message.

 ## How the transport works
 
 Vanilla `useChat` expects an `api` URL — it POSTs the conversation to your own Next.js route handler, which terminates the stream. `useTriggerChatTransport` replaces that round-trip: instead of an `api` URL, you pass a custom [`ChatTransport`](https://ai-sdk.dev/docs/ai-sdk-ui/transport) that talks directly to the Trigger.dev cloud (or your self-hosted webapp) on behalf of `useChat`.

 An AI chat isn't a request — it's a session. `chat.agent` runs every conversation as a single long-lived Trigger.dev task: you write the loop, it wakes up when a message arrives, freezes when none do, and the same in-memory state and on-disk workspace survive across page refreshes, deploys, idle gaps, and crashes. The substrate handles the parts most teams stitch together by hand — turn lifecycle, mid-stream resume, recovery from cancel/crash/OOM, HITL approvals, deploy upgrades — so your code is the loop you'd write anyway: messages in, `streamText` out.

 Most chat UIs treat conversations as linear sequences. But real conversations branch — users edit previous messages, regenerate responses, undo exchanges, and explore alternative paths.

 Some turns need to stop and ask the user something before they can finish — picking between options, confirming a destructive action, or clarifying an ambiguous request. The AI SDK calls this **human-in-the-loop** (HITL), and the building block is a tool with no `execute` function.
 
 When the LLM calls a tool that has no `execute`, `streamText` ends with the tool call still pending. The turn completes cleanly, the frontend renders UI to collect the answer, and when the user responds, a new turn resumes with the answer merged into the same assistant message.

 `chat.agent` runs are processes — they boot, stream a turn, and either suspend (waiting for the next message) or exit. When the next message arrives at a session whose previous run already exited, a **fresh** run boots with no in-memory state. Something has to rebuild the conversation history before that turn can produce a coherent response.

 When a `chat.agent` run dies in the middle of streaming a response — the user cancels, the worker OOMs, or an unhandled exception kills the process — the durable streams hold what was in flight. The next run boots as a continuation, reads both stream tails, and reconstructs a chain that preserves the partial response so any follow-up (`keep going`, `actually do X instead`, a new question) has full context.
 
 The behavior is automatic. The `onRecoveryBoot` hook is opt-in for policies that need something different.

 Agent skills are reusable capabilities you ship as folders — a `SKILL.md` describing when and how to use them, plus optional scripts, references, and assets.

 A common need for chat-style endpoints is to drive agent behavior from **server-trusted signals** that the browser cannot be allowed to declare itself — bot management scores, JA4 fingerprints, ASN, ReCAPTCHA verdicts, or any other anti-abuse data only the edge can see. The agent's [`clientData`](/ai-chat/reference#withclientdata) channel is the right delivery mechanism, but `clientData` set in the browser is by definition spoofable. The fix is to move the value population out of the browser and into a trusted edge proxy.
 
 This page documents the pattern using Cloudflare Workers as the proxy. The same shape applies to any edge layer (custom reverse proxy, Vercel Edge Middleware, AWS Lambda@Edge) — the trust comes from the deployment topology, not from Trigger.dev validating the source.
