Disable checkout for PR risk classifier - #879
Merged

Conversation
The API-only risk classifier does not execute pull request code, but its generated workflow attempted to check out contributor branches. This caused pull_request_target runs for fork PRs to fail when the author lacked write permission. Disable checkout and regenerate the lock with gh-aw v0.83.4.

Pull request overview
Disables repository/PR-branch checkout for the classify-pull-request-risk gh-aw workflow, aligning the generated Actions workflow with the intended API-only execution model for pull_request_target (avoiding fork-permission checkout failures).
Changes:
- Add
checkout: falseto the workflow markdown definition to prevent any repo/PR checkout. - Regenerate the compiled lock workflow, removing checkout-related steps and outputs.

Summary
gh-aw v0.83.4Rationale
The classifier runs from
pull_request_targetand reads pull request data through GitHub APIs; it explicitly does not execute contributor code. Its generated agent job nevertheless attempted to check out the PR branch. For fork PRs,gh-awrejects that checkout when the actor lacks repository write permission, so the workflow failed before inference.checkout: falseremoves that unnecessary checkout and lets external-contributor PRs reach classification without weakening the trust boundary.Failed run: https://github.com/microsoft/agent-framework-go/actions/runs/32364877561/job/96418371409
