| name | pr-followup |
| description | Analyze a GitHub pull request's latest discussion and act on pending review feedback or requested changes. Use when the user wants to address PR review comments, respond to reviewer feedback, or asks to "follow up on PR |
Analyze the pull request at $PR_URL and take any necessary action based on the current state of discussion.
Context
- Your GitHub Username:
$GITHUB_USERNAME (from global CLAUDE.md or prompt)
- Current Workspace: This is your fork of the original repository
- Remote Origin: Set to
$GITHUB_USERNAME/[original-repo-name]
- Target: All commits/pushes go to your fork, PR updates the existing PR
GitHub Tools
- GitHub MCP: Preferred for collaboration (PRs, issues, comments, reviews). Tool names follow
mcp__github__*.
- gh CLI: Fallback when MCP unavailable -
gh --help for commands
Steps
1. Fetch Full PR Context (GitHub MCP)
Using GitHub MCP tools, collect:
- PR title, description, base branch, head branch
- All review comments (inline code comments with threads)
- All issue comments (general discussion)
- All review submissions (approved / changes requested / commented)
- Current PR status (open / closed / merged / draft)
- CI/check statuses (passing / failing)
- List of changed files and their diffs
2. Build a Timeline
Reconstruct the full conversation in chronological order:
- Who said what, when
- Which comments are on which lines/files
- Which comments are resolved vs. unresolved
- Identify your last action (your last commit, comment, or reply) using
$GITHUB_USERNAME
3. Identify Everything That Happened After Your Last Action
Focus only on events after your last commit or comment:
- New review requests or change requests
- New inline comments on code
- Reviewer replies to your responses
- Automated bot messages (CI failures, size checks, etc.)
- Any explicit instructions or requests made to you
4. Dynamically Determine What Needs to Be Done
Do NOT use a static checklist. Instead, reason about the current situation:
- Read each unresolved comment or request carefully
- Understand the intent behind each message (not just the literal words)
- Group related requests together
- Determine which are actionable by you right now vs. waiting on someone else
- Prioritize: blocking issues first, then suggestions, then nits
Examples of things you might discover (non-exhaustive):
- A reviewer asked you to revert a specific change
- Someone requested a test be added or removed
- A CI check is failing and a fix is implied
- A reviewer approved but left a minor suggestion
- Someone asked for clarification and is waiting for your reply
- A merge conflict appeared that needs resolution
- The PR description needs to be updated
5. Present Your Action Plan
Before doing anything, clearly summarize:
- What has happened since your last action (brief timeline)
- What you believe needs to be done, and why (reasoning from the comments)
- Exact steps you plan to take (files, changes, replies, etc.)
- Anything ambiguous that you need clarification on
Wait for approval before proceeding.
6. Execute (After Approval)
Carry out each action:
- Make code changes as requested
- Run tests and verify they pass
- Commit with conventional format (fix:, revert:, test:, etc.) referencing the PR
- Push to your fork
- Use GitHub MCP to reply to reviewer comments and mark them as addressed
- If a change is reverted, explain why in the commit message and PR comment
Rules
- ALWAYS use GitHub MCP for GitHub operations (comments, replies, PR updates)
- Run commands one at a time — never chain with
&&
- Never assume intent — if a comment is ambiguous, ask
- Do not make unrelated changes while addressing feedback
- Always reply to reviewers after making their requested changes
- NO emojis in PR comments or replies - keep communication professional
- Match the communication style of existing project comments
- Be concise and technical in feedback responses
- GitHub username:
$GITHUB_USERNAME
