Agent Skills: Watch CI

Watch CI

Poll the GitHub Actions CI pipeline for the current HEAD commit until all jobs finish.

Environment

The gh CLI is not available in the Claude VM. Use the GitHub REST API via curl. The repo is codervisor/lean-spec.

Steps

1. Get the current commit SHA and branch:

   SHA=$(git rev-parse HEAD)
   BRANCH=$(git branch --show-current)
   echo "Watching CI for commit $SHA on branch $BRANCH"
   

2. Find the workflow run matching our exact commit. The API returns runs newest-first; filter by head_sha. If the run hasn't appeared yet (GitHub can take a few seconds), retry up to 5 times with 10s waits:

   curl -sH "Accept: application/vnd.github+json" \
     "https://api.github.com/repos/codervisor/lean-spec/actions/runs?branch=$BRANCH&head_sha=$SHA&per_page=1" \
     | python3 -c "
   import json, sys
   data = json.load(sys.stdin)
   runs = data.get('workflow_runs', [])
   if not runs:
       print('NO_RUNS'); sys.exit()
   r = runs[0]
   print(f'RUN_ID={r[\"id\"]}')
   print(f'Status: {r[\"status\"]}  Conclusion: {r.get(\"conclusion\") or \"pending\"}  Commit: {r[\"head_sha\"][:8]}')"
   

3. Poll jobs until all complete (every 60s for Rust builds which take ~8-10 min):

   curl -sH "Accept: application/vnd.github+json" \
     "https://api.github.com/repos/codervisor/lean-spec/actions/runs/$RUN_ID/jobs" \
     | python3 -c "
   import json, sys
   data = json.load(sys.stdin)
   for j in data.get('jobs', []):
       steps = [s for s in j.get('steps', []) if s['status'] == 'in_progress']
       step_info = f' -> {steps[0][\"name\"]}' if steps else ''
       print(f'{j[\"name\"]:40}  {j[\"status\"]:12}  {j.get(\"conclusion\") or \"\"}{step_info}')"
   

4. On failure, fetch the failed job logs to diagnose:

   curl -sH "Accept: application/vnd.github+json" \
     "https://api.github.com/repos/codervisor/lean-spec/actions/runs/$RUN_ID/jobs" \
     | python3 -c "
   import json, sys
   data = json.load(sys.stdin)
   for j in data.get('jobs', []):
       if j.get('conclusion') == 'failure':
           print(f'FAILED: {j[\"name\"]} (id: {j[\"id\"]})')
           for s in j.get('steps', []):
               if s.get('conclusion') == 'failure':
                   print(f'  Step: {s[\"name\"]}')"
   

CI Structure

• node (~2 min): pnpm install, build, typecheck, test
• rust (~8-10 min, depends on node): cargo fmt, clippy, build, test, TS binding export

Reporting

Give the user a brief status update each poll cycle. On completion, summarize:

• Overall result (success/failure)
• Per-job results
• If failed: which step failed and relevant error output
