Review Comments

Pull PR review comments and feedback, understand the reviewer's intent, implement fixes, and push updates. The goal is to resolve all actionable feedback in a single pass so the PR can move forward.

Input

If $ARGUMENTS provides a PR number, use it. Otherwise, detect the current PR:

PR_NUMBER=$(gh pr view --json number --jq '.number' 2>/dev/null)

If no PR is found, ask the user for the PR number.

Step 1: Fetch Comments and Reviews

Gather all review feedback from the PR:

# Get repo info
REPO=$(gh repo view --json nameWithOwner --jq '.nameWithOwner')

# Get PR review comments (inline code comments) — includes file path and line
gh api "repos/${REPO}/pulls/${PR_NUMBER}/comments" \
  --jq '.[] | {id: .id, path: .path, line: .line, body: .body, user: .user.login, created: .created_at, in_reply_to: .in_reply_to_id}'

# Get PR reviews (top-level review bodies with approval state)
gh api "repos/${REPO}/pulls/${PR_NUMBER}/reviews" \
  --jq '.[] | {id: .id, state: .state, body: .body, user: .user.login}'

# Get issue comments (general PR conversation)
gh api "repos/${REPO}/issues/${PR_NUMBER}/comments" \
  --jq '.[] | {id: .id, body: .body, user: .user.login, created: .created_at}'

Group comments into threads using in_reply_to_id — read the full thread before acting on any individual comment, since later replies may refine or resolve earlier ones.

Step 2: Categorize Comments

| Category | Action | |----------|--------| | Code change requested | Implement the fix | | Question / clarification | Read context and draft a reply | | Suggestion (optional) | Evaluate — implement if it improves the code, explain trade-off if not | | Approval / praise | No action needed | | Already resolved | Skip (check if thread is marked resolved) |

For each actionable comment, note:

• File path and line number
• What the reviewer is asking for
• Whether it requires a code change or just a response
• Whether it's part of a thread (read the full thread for context)

Step 3: Address Each Comment

For each actionable comment, in order:

1. Read the relevant file at the referenced line (with surrounding context)
2. Understand the reviewer's concern — what problem are they pointing out?
3. Implement the fix using Edit tool, or draft a reply if it's a question
4. Verify the fix doesn't break anything (run relevant tests if available)

Handling disagreements: If a reviewer's suggestion would introduce a regression, reduce type safety, or conflict with project conventions, don't silently ignore it. Draft a respectful reply explaining the trade-off and let the user decide whether to post it. Present it as:

Reviewer @name suggested X on file.ts:42.
I think this would [concern]. Draft reply:
  "Thanks for the suggestion! I considered X but went with Y because [reason].
   Happy to discuss if you feel strongly about this."
Post this reply? [y/N]

Group related comments that affect the same file — make all changes to a file before moving on.

Step 4: Commit and Push

After all changes are made, stage only the files that were modified to address comments:

# Stage specific changed files (NOT git add -A which could catch unrelated changes)
git add path/to/changed-file1.ts path/to/changed-file2.ts
git commit -m "address review comments from PR #${PR_NUMBER}"
git push

Step 5: Resolve Comment Threads

After pushing fixes (or posting replies for disagreements), resolve each addressed thread on GitHub so it no longer blocks merge under branch protection rules that require resolved conversations.

Read and follow "${CLAUDE_PLUGIN_ROOT}/references/review-thread-resolution.md" for the full workflow. Summary:

1. Fetch unresolved review threads via GraphQL
2. For each thread addressed in steps above, resolve it via resolveReviewThread mutation
3. Verify remaining unresolved count

Resolution rules:

• Code change implemented → resolve the thread
• Reply posted (disagreement or clarification) → resolve the thread
• Approval / praise → already not blocking, skip
• Could not address → do NOT resolve; leave for human review

Output Format

## PR Review Comments — #${PR_NUMBER}

### Comments Addressed

1. **@reviewer** on `path/to/file.ts:42`
   - Comment: "This should use optional chaining instead of non-null assertion"
   - Action: Changed `user!.name` to `user?.name ?? ''`

2. **@reviewer** on `path/to/file.ts:89`
   - Comment: "Missing error handling for the API call"
   - Action: Added try/catch with proper error propagation

### Questions Answered

3. **@reviewer** on general
   - Question: "Why did you choose X over Y?"
   - Reply: {drafted reply — post via gh api if requested}

### Disagreements (Needs Decision)

4. **@reviewer** on `path/to/file.ts:120`
   - Suggestion: "Use a map instead of switch"
   - Analysis: The switch is more readable here and has exhaustiveness checking.
   - Draft reply ready — awaiting your decision.

### No Action Needed

5. **@reviewer**: "LGTM" (approval)

### Summary
- Code changes: {N}
- Questions answered: {N}
- Disagreements flagged: {N}
- Skipped (resolved/approval): {N}
- Commit: {short hash} pushed to branch
