Babysitting a PR

Use this skill when the user has an open pull request and wants the agent to monitor it, fix CI failures, resolve review comments, and keep it merge-ready.

Steps

1. Get the PR status — fetch the current state of the PR:

   gh pr view --json number,title,state,mergeable,reviewDecision,statusCheckRollup,comments,reviews
   

   Also check for merge conflicts:

   gh pr view --json mergeStateStatus
   

2. Check CI status — look at the statusCheckRollup field. For each failing check:

   gh pr checks
   

   This lists all CI checks and their status (pass/fail/pending).

3. Fix CI failures — for each failing check, get the logs:

   gh run view <run-id> --log-failed
   

   Analyze the failure and fix it:

   • Lint failures: run the linter locally (npm run lint -- --fix), fix remaining issues manually, commit.
   • Type errors: run npx tsc --noEmit, read the errors, fix the types, commit.
   • Test failures: run the failing test suite locally, read the assertion errors, fix the code or update the test expectations, commit.
   • Build failures: run npm run build, read the error output, fix imports/configs/missing deps, commit.

   After fixing, push the changes:

   git add -A && git commit -m "fix: resolve CI failures" && git push
   

4. Handle review comments — fetch PR review comments:

   gh api repos/{owner}/{repo}/pulls/{pr}/comments
   

   For each unresolved comment:

   • Read the comment and the code it references.
   • If the fix is clear (typo, naming, missing null check, style issue), apply it.
   • If the comment requires a design decision or clarification, skip it and report to the user.

   Commit fixes for resolved comments:

   git add -A && git commit -m "fix: address review feedback" && git push
   

5. Resolve merge conflicts — if the PR has conflicts:

   git fetch origin main
   git merge origin/main
   

   Resolve conflicts by reading both sides and choosing the correct resolution. For ambiguous conflicts, ask the user. After resolving:

   git add -A && git commit -m "fix: resolve merge conflicts" && git push
   

6. Re-check status — after pushing fixes, wait for CI to run and check again:

   gh pr checks --watch
   

   If new failures appear, go back to step 3. Limit to 3 rounds to avoid infinite loops.

7. Report — summarize what was done:

   • Which CI checks were failing and how they were fixed
   • Which review comments were addressed
   • Whether merge conflicts were resolved
   • Current PR status (ready to merge, or what's still blocking)

Loop Behavior

This skill is designed to run in a loop:

Check PR → Find issues → Fix issues → Push → Re-check → Repeat

Stop when:

• All checks pass, no unresolved comments, no conflicts → PR is merge-ready
• 3 fix-push-check cycles have been attempted without full resolution → report what's still failing
• A fix requires a design decision → ask the user

Notes

• Never force-push to a shared PR branch.
• Don't modify test assertions to make tests pass unless the behavior change was intentional.
• Don't resolve review comments you're unsure about — skip them and let the user know.
• If CI is queued/pending, wait for it to complete before analyzing failures.
• Use gh pr ready to mark the PR as ready for review once everything is green.
