GitHub PR Review

Resolves Pull Request review comments with severity-based prioritization, fix application, and thread replies.

Quick Start

# 1. Check project conventions
cat CLAUDE.md 2>/dev/null | head -50

# 2. Get PR and repo info
PR=$(gh pr view --json number -q '.number')
REPO=$(gh repo view --json nameWithOwner -q '.nameWithOwner')

# 3. Fetch comments
gh api repos/$REPO/pulls/$PR/comments

# 4. For each comment: read → analyze → fix → verify → commit → reply

# 5. Run tests
make test

# 6. Push when all fixes verified
git push

Pre-Review Checklist

Before processing comments, verify:

1. Project conventions: Read CLAUDE.md or similar
2. Commit format: Check git log --oneline -5 for project style
3. Test command: Identify test runner (make test, pytest, npm test)
4. Branch status: git status to ensure clean working tree

Core Workflow

1. Fetch PR Comments

PR=$(gh pr view --json number -q '.number')
REPO=$(gh repo view --json nameWithOwner -q '.nameWithOwner')
gh api repos/$REPO/pulls/$PR/comments

2. Classify by Severity

Process in order: CRITICAL > HIGH > MEDIUM > LOW

3. Process Each Comment

For each comment:

a. Show context

Comment #123456789 (HIGH) - app/auth.py:45
"The validation logic should use constant-time comparison..."

b. Read affected code and propose fix

c. Confirm with user before applying

d. Apply fix if approved

e. Verify fix addresses ALL issues in the comment

4. Commit Changes

Use proper format for review fixes:

git add <files>
git commit -m "$(cat <<'EOF'
fix(scope): address review comment #ID

Brief explanation of what was wrong and how it's fixed.
Addresses review comment #123456789.
EOF
)"

Review fix commit rules:

• First line: type(scope): subject (max 50 chars)
• Types: fix, refactor, security, test, style, perf
• Reference the comment ID in body

5. Reply to Thread

COMMIT=$(git rev-parse --short HEAD)
gh api repos/$REPO/pulls/$PR/comments \
  --input - <<< '{"body": "Fixed in '"$COMMIT"'. [brief description].", "in_reply_to": 123456789}'

Standard Reply Templates:

6. Run Tests

make test  # or project-specific command

All tests must pass before pushing.

7. Push

git push

8. Submit Review (Optional)

# Approve the PR
gh pr review $PR --approve --body "All review comments addressed. Ready to merge."

# Or request changes if issues remain
gh pr review $PR --request-changes --body "Addressed X comments, Y issues remain."

# Or just comment
gh pr review $PR --comment --body "Partial progress: fixed A and B, working on C."

Batch Commit Strategy

Organize commits by impact:

Workflow:

1. Fix CRITICAL/HIGH → separate commits each
2. Collect all cosmetic fixes
3. Apply cosmetics → single style: commit
4. Run tests once
5. Push all together

Pre-Merge Checklist

Before closing/merging PR:

• All CRITICAL and HIGH comments addressed
• All MEDIUM comments addressed or justified skip
• Replies posted to all resolved threads
• Tests passing
• Linting passing
• CI checks green
• No unresolved conversations

Reply to Threads API

Important: Use --input - with JSON for in_reply_to:

# Correct syntax
gh api repos/$REPO/pulls/$PR/comments \
  --input - <<< '{"body": "Fixed in abc123.", "in_reply_to": 123456789}'

Important Rules

• ALWAYS read project conventions before starting
• ALWAYS confirm before modifying files
• ALWAYS verify ALL issues in multi-issue comments are fixed
• ALWAYS run tests before pushing
• ALWAYS reply to resolved threads using standard templates
• ALWAYS submit formal review after addressing all comments
• NEVER skip HIGH/CRITICAL comments without explicit user approval
• Functional fixes → separate commits (one per fix)
• Cosmetic fixes → batch into single style: commit
