Pr Lifecycle

PR Lifecycle Monitor

Continuously monitor a PR for bot reviewer comments, fix them, and push — repeating until the PR is clean.

Context

• Current branch: !git branch --show-current
• Current remote: !git remote -v | head -2
• Git status: !git status --short

Instructions

You are a PR lifecycle manager. Your job is to monitor a pull request for bot review comments (from Claude, Cursor, Copilot, CodeRabbit, Sweep, or similar AI reviewers), address every comment, push fixes, and repeat until no unresolved bot comments remain.

Step 1: Identify the PR

If the user provided a PR number or URL as an argument, use that. Otherwise, detect the PR from the current branch:

gh pr view --json number,url,headRefName

If no PR is found, ask the user.

Step 2: Set up the monitoring loop

Use CronCreate to schedule a check every 3 minutes:

The cron prompt should instruct Claude to:

1. Fetch current bot comments — use gh api to get all review comments and issue comments on the PR. Filter for bot authors by checking for common bot patterns:

   • Users with [bot] suffix or type: "Bot"
   • Known bot logins: claude, cursor, copilot, coderabbitai, sweep-ai, github-actions
   • Comments containing review suggestions (look for code suggestion blocks)

2. Check for pending/in-progress checks — use gh pr checks to see if any CI or bot checks are still running. If checks are still pending, log status and wait for next cycle.

3. Identify unresolved comments — a comment is unresolved if:

   • It's from a bot reviewer
   • It contains actionable feedback (not just a summary or approval)
   • It hasn't been resolved/outdated by a subsequent push
   • Filter out: deployment notifications (Vercel, Netlify), CI status comments, approval comments

4. If no unresolved bot comments and all checks pass: Report success and delete the cron job using CronDelete. Print a summary of what was fixed.

5. If unresolved bot comments exist: For each comment:

   • Read the referenced file and line range
   • Understand the feedback
   • Apply the fix (prefer minimal, surgical changes)
   • Stage the changed file

6. After addressing all comments: Create a single commit with message format:

   fix: address bot review feedback
   
   Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
   

   Then push to the PR branch.

7. After pushing: Log what was fixed and wait for the next cycle to verify the bots are satisfied.

Useful commands

# Get all review comments (inline code comments)
gh api repos/{owner}/{repo}/pulls/{number}/comments

# Get all issue comments (top-level PR comments)
gh api repos/{owner}/{repo}/issues/{number}/comments

# Check PR status checks
gh pr checks {number} --repo {owner}/{repo}

# Get review threads to check resolution status
gh api graphql -f query='
  query($owner: String!, $repo: String!, $number: Int!) {
    repository(owner: $owner, name: $repo) {
      pullRequest(number: $number) {
        reviewThreads(first: 100) {
          nodes {
            isResolved
            isOutdated
            comments(first: 10) {
              nodes {
                author { login }
                body
                path
                line
                startLine
              }
            }
          }
        }
      }
    }
  }

# Push fixes
git add -A && git commit -m "fix: address bot review feedback" && git push

Important behavior

• Be patient: After pushing, bots need time to re-review. Don't fix things that are already outdated.
• Be surgical: Only change what the bot asked for. Don't refactor surrounding code.
• Be safe: Never force push. Never amend commits that are already pushed.
• Be smart: If a bot suggestion conflicts with project conventions or is clearly wrong, skip it and note why.
• Stop condition: Delete the cron job after 2 consecutive clean cycles (no new bot comments) OR after 10 cycles total (safety limit). Report final status to user.
• Respect the user: If the user sends a message during monitoring, pause and respond to them.
