The board's built-in auto-add workflow only fires on PR open/reopen, not when a draft is converted to ready for review. This GHA covers that gap by triggering on opened, reopened, and ready_for_review, skipping drafts. Assisted-by: Claude Sonnet 4.6

There was a problem hiding this comment.
Sgtm, I fit into this use case. 🙂 Also fine with me that contrib and core PRs are on the same board.
…kflow pull_request trigger cannot access secrets for fork PRs (Secret source: None). pull_request_target runs in base repo context and can access secrets. Use otelbot app token (same pattern as backport.yml) instead of a PAT. No checkout step — intentional, see open-telemetry/opentelemetry-python#4955. Assisted-by: Claude Sonnet 4.6

Description
The Python PR digest board uses a built-in GitHub project workflow to auto-add PRs. However, that workflow only fires on PR `opened` and `reopened` events — it does not fire when a draft PR is converted to ready for review.
This means any PR opened as a draft and later marked ready for review is silently skipped and never added to the board.
This GHA covers the gap by triggering on `opened`, `reopened`, and `ready_for_review`, while skipping drafts. Since it uses `actions/add-to-project` (which is idempotent), PRs opened as non-drafts are safe — they'll just be a no-op on the second trigger.
Mirrors: open-telemetry/opentelemetry-python#5026
Security: `pull_request_target` trigger
This workflow uses `pull_request_target` rather than `pull_request`. This is intentional: `pull_request` does not have access to repository secrets for fork PRs (`Secret source: None`), so the otelbot token would never resolve. `pull_request_target` runs in the base repo context and can access secrets.
The workflow contains no `actions/checkout` step — it never executes any code from the fork, only uses the PR node ID to make a single GitHub API call. See open-telemetry/opentelemetry-python#4955 for the full security discussion.
Prerequisites for org admins
Before this workflow will function after merge, an org admin must grant otelbot the Projects permission:
