ci: Cancel in-progress CI jobs when a PR is closed or merged#5725
Conversation
The existing concurrency groups use `github.ref` which for PRs resolves to `refs/pull/<number>/merge`. When a PR is merged, the push to main creates a different concurrency group (`refs/heads/main`), so the still-running PR workflows are never cancelled, wasting CI resources. This adds a new workflow that triggers on `pull_request: closed` (fired on both merge and manual close) and cancels all in-progress and queued workflow runs for the PR's head branch via the GitHub API.

Wrap the cancelWorkflowRun call in try/catch so that if a run completes between the list and cancel calls, the error doesn't abort cancellation of the remaining runs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Problem
The existing concurrency groups use
github.ref, which for PRs resolves torefs/pull/<number>/merge. When a PR is merged, the push to main creates a different concurrency group (refs/heads/main), so the still-running PR workflows are never cancelled. This wastes CI resources, especially for expensive jobs like native tests, E2E, and sample app builds.Solution
A new lightweight workflow that:
pull_request: closed(fires on both merge and manual close)in_progressandqueuedworkflow runs for the PR's head branchThe workflow uses
actions/github-scriptwith the defaultGITHUB_TOKEN— no extra permissions needed.🤖 Generated with Claude Code
