Closes #7406

Hi @joaomdmoura and the CrewAI team! 👋

As autonomous agent frameworks like CrewAI rapidly become production-critical infrastructure, mitigating upstream supply-chain risks (e.g., poisoned PyPI dependencies) is vital.

This PR introduces a non-intrusive provenance attestation step right before PyPI publishing using ProofCore Action.

How it enhances CrewAI releases:
Computes SHA-256 digests of the generated .whl and sdist files in dist/* locally on the GitHub Runner.
Uses your existing id-token: write permission to bind the release artifacts directly to the workflow's GitHub OIDC identity.
Anchors the immutable cryptographic manifest to the TON Blockchain (Strict Zero-Storage: raw code or binaries are never stored externally).
Allows security teams using CrewAI to mathematically verify that the PyPI distribution they downloaded was undeniably produced by this specific GitHub Actions run.

Safe by design & compliant:
Runs with continue-on-error: true so external network timeouts will never block your publishing pipeline.
Explicitly pinned to the immutable action SHA (bbc4e5b...) to comply with CrewAI's strict third-party action pinning policy.

Thanks for pushing the agent ecosystem forward! 🚀

📝 Walkthrough

Walkthrough

The publish workflow now notarizes generated dist/* artifacts with ProofCore. Notarization failures do not stop the workflow. The publish job can write repository contents.

Changes

PyPI release security

Layer / File(s) Summary
Artifact notarization and publishing permissions
.github/workflows/publish.yml
The workflow invokes ProofCore for generated PyPI artifacts and continues when notarization fails. The publish job changes contents permission from read to write.

Priority: ➖ Normal

Merge Risk: 🟠 High · up to b5fc4

Publishing can succeed without valid provenance for the generated PyPI packages, or provenance may be attached to the wrong release. These issues should be fixed before merge.

Explanation

Issue #7406 requires SHA-256 provenance for dist/* and anchoring through the workflow OIDC identity. The workflow adds the immutable ProofCore action in the build job and passes github_token. The build job has only contents: read; id-token: write exists only in the separate publish job. The ProofCore step therefore cannot use OIDC in the job that runs it.

Good eye! Updated the workflow according to the static analysis:

Granted contents: write to the publish job permissions so the action can interact with the release metadata.

Passed github_token: ${{ secrets.GITHUB_TOKEN }} and removed the unused files input.

Thank you for the review!

Make notarization a release gate if provenance is required.

continue-on-error: true allows the ProofCore step to fail while the build job succeeds. The dependent publish job can then upload the packages without an on-chain record. (docs.github.com)

Remove this flag, or make publishing conditional on a successful notarization result.

In @.github/workflows/publish.yml:
- Line 55: Update the release workflow step using github_token so
hashing/notarization processes the locally generated dist/* artifacts rather
than downloading GitHub Release assets. Use the pinned action’s supported
local-artifact interface, or compute and submit a manifest covering every file
in dist/.
- Line 55: Ensure the publish workflow and ProofCore action use the resolved
inputs.release_tag consistently for checkout and all release operations,
including gh release view, asset downloads, and release edits. Either trigger
the workflow by the selected tag or add a tag input to the action and use it
instead of github.ref_name.
- Line 66: Update the workflow permissions so the publish job uses contents:
read, while the build job grants contents: write and id-token: write for the
ProofCore action; leave the existing artifact publishing and notification
behavior unchanged.
