Iterate on PR Until CI Passes

Continuously iterate on the current branch until all CI checks pass and review feedback is addressed.

When to Use This Skill

Use this skill when:

• Fixing CI failures
• Addressing review feedback
• Continuously pushing fixes until all checks are green
• Automating the feedback-fix-push-wait cycle
• Ensuring PR meets all quality gates

Requires: GitHub CLI (gh) authenticated and available.

Process

Step 1: Identify the PR

gh pr view --json number,url,headRefName,baseRefName

If no PR exists for the current branch, stop and inform the user.

Step 2: Check CI Status First

Always check CI/GitHub Actions status before looking at review feedback:

gh pr checks --json name,state,bucket,link,workflow

The bucket field categorizes state into: pass, fail, pending, skipping, or cancel.

Important: If any of these checks are still pending, wait before proceeding:

• sentry / sentry-io
• codecov
• cursor / bugbot / seer
• Any linter or code analysis checks

These bots may post additional feedback comments once their checks complete. Waiting avoids duplicate work.

Step 3: Gather Review Feedback

Once CI checks have completed (or at least the bot-related checks), gather human and bot feedback:

Review Comments and Status:

gh pr view --json reviews,comments,reviewDecision

Inline Code Review Comments:

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

PR Conversation Comments (includes bot comments):

gh api repos/{owner}/{repo}/issues/{pr_number}/comments

Look for bot comments from: Sentry, Codecov, Cursor, Bugbot, Seer, and other automated tools.

Step 4: Investigate Failures

For each CI failure, get the actual logs:

# List recent runs for this branch
gh run list --branch $(git branch --show-current) --limit 5 --json databaseId,name,status,conclusion

# View failed logs for a specific run
gh run view <run-id> --log-failed

Do NOT assume what failed based on the check name alone. Always read the actual logs.

Step 5: Validate Feedback

For each piece of feedback (CI failure or review comment):

1. Read the relevant code - Understand the context before making changes
2. Verify the issue is real - Not all feedback is correct; reviewers and bots can be wrong
3. Check if already addressed - The issue may have been fixed in a subsequent commit
4. Skip invalid feedback - If the concern is not legitimate, move on

Step 6: Address Valid Issues

Make minimal, targeted code changes. Only fix what is actually broken.

Step 7: Commit and Push

git add -A
git commit -m "fix: <descriptive message of what was fixed>"
git push origin $(git branch --show-current)

Step 8: Wait for CI

Use the built-in watch functionality:

gh pr checks --watch --interval 30

This waits until all checks complete. Exit code 0 means all passed, exit code 1 means failures.

Alternatively, poll manually if you need more control:

gh pr checks --json name,state,bucket | jq '.[] | select(.bucket != "pass")'

Step 9: Repeat

Return to Step 2 if:

• Any CI checks failed
• New review feedback appeared

Continue until all checks pass and no unaddressed feedback remains.

Exit Conditions

Success:

• All CI checks are green (bucket: pass)
• No unaddressed human review feedback

Ask for Help:

• Same failure persists after 3 attempts (likely a flaky test or deeper issue)
• Review feedback requires clarification or decision from the user
• CI failure is unrelated to branch changes (infrastructure issue)

Stop Immediately:

• No PR exists for the current branch
• Branch is out of sync and needs rebase (inform user)

Tips

• Use gh pr checks --required to focus only on required checks
• Use gh run view <run-id> --verbose to see all job steps, not just failures
• If a check is from an external service, the link field in checks JSON provides the URL to investigate
