Respond to PR Review

Systematically triage, address, and respond to every review comment on a pull request. No comment should be silently skipped.

Core Principle

Every review comment gets an explicit disposition. A comment is either:

1. Accepted — the feedback is valid, fix the code and respond
2. Acknowledged — the feedback is valid but out of scope for this PR; respond explaining why and what follow-up is planned
3. Disputed — the feedback is incorrect or conflicts with project rules; respond with a concrete explanation referencing the relevant invariant or rationale

Never silently skip a comment. Never dismiss a comment just because it is non-blocking, a suggestion, or an improvement rather than a bug. CodeRabbit is configured with project-specific rules — its feedback reflects project standards and should be treated with the same rigor as human review comments.

Instructions

1. Determine PR number

If not provided, detect from current branch:

gh pr view --json number -q .number

2. Fetch all review comments and threads

Fetch both issue-level comments and inline review threads:

# Inline review comments
gh api repos/{owner}/{repo}/pulls/{pr}/comments

# Issue-level comments (summaries, top-level feedback)
gh api repos/{owner}/{repo}/issues/{pr}/comments

# Review thread resolution status
gh api graphql -f query='
query {
  repository(owner: "{owner}", name: "{repo}") {
    pullRequest(number: {pr}) {
      reviewThreads(first: 100) {
        nodes {
          id
          isResolved
          comments(first: 10) {
            nodes {
              author { login }
              body
              path
              line
              createdAt
              updatedAt
            }
          }
        }
      }
    }
  }
}'

3. Check for updated comments

Compare createdAt vs updatedAt on each comment. If a comment was updated after a previous response, it means the reviewer edited their feedback — treat it as new input that needs re-evaluation.

Also check for reply chains: if a reviewer responded to your previous reply, that thread needs attention regardless of resolution status.

4. Build a triage table

For EVERY unresolved comment (and resolved comments with new replies), create a triage entry:

Fill in Source (coderabbitai[bot], human username), the file and line, a one-sentence summary of the issue, and leave Disposition/Action blank.

Present this table to the user and ask for confirmation before proceeding. The user may override dispositions or skip specific comments.

5. Read code and triage each comment

For each comment, read the relevant code and determine the disposition:

• Accept: The issue is real and should be fixed in this PR
• Acknowledge: The issue is real but belongs in a follow-up (explain why — scope, risk, separate concern)
• Dispute: The issue is incorrect — cite the specific invariant, spec, or technical reason

Do not use weasel language like "just a suggestion", "non-blocking", or "nice to have" to skip valid feedback. If the feedback identifies a real issue (bug, regression, accessibility problem, spec violation), it should be accepted regardless of how the reviewer labeled its severity.

6. Fix accepted issues

For each accepted comment:

1. Fix the code
2. Reply to the thread explaining the fix

7. Respond to acknowledged/disputed comments

For each non-accepted comment, reply to the thread with:

• Acknowledged: What the issue is, why it's deferred, and what follow-up is planned (e.g., "Will address in a separate PR" or "Tracking as part of [issue]")
• Disputed: The concrete technical reason the feedback doesn't apply, referencing project invariants or specs where relevant

8. Post replies

All responses MUST end with the agent signature:

🤖 _Response by [Claude Code](https://claude.com/claude-code)_

Write the response to a temp file first (to avoid heredoc issues), then post:

mkdir -p /tmp/claude

printf '%s\n' \
  '[response body]' \
  '' \
  '🤖 _Response by [Claude Code](https://claude.com/claude-code)_' \
  > /tmp/claude/pr-comment.md

gh api graphql -f query='
mutation($body: String!) {
  addPullRequestReviewThreadReply(input: {
    pullRequestReviewThreadId: "{thread_id}"
    body: $body
  }) {
    comment { id }
  }
}' -f body="$(cat /tmp/claude/pr-comment.md)"

rm /tmp/claude/pr-comment.md

9. Resolve threads

Only resolve threads where the disposition is Accept (code was fixed) or Dispute (with explanation posted). Do NOT resolve Acknowledged threads — those stay open as a reminder for follow-up.

gh api graphql -f query='
mutation {
  resolveReviewThread(input: { threadId: "{thread_id}" }) {
    thread { isResolved }
  }
}'

10. Commit and push

Commit all fixes with a message referencing the review feedback, then push.

11. Report final status

After all comments are handled, present the completed triage table with final dispositions:

This gives the user a clear audit trail of what was done with every comment.

Examples

User says: "Check the PR comments" Action: Fetch all comments, build triage table, present for review, then address each systematically

User says: "Address the review feedback on PR 42" Action: Fetch comments for PR #42, triage all, fix accepted issues, respond to all threads, report status

User says: "Any new review comments?" Action: Fetch comments, check for updated/new comments since last response, triage only the new ones
