PR Review

Reviews code changes for quality, security, and pattern compliance.

When to Use

• "Review this PR"
• "Check these changes"
• "Code review for..."
• "Is this safe to merge?"
• "Review my changes"

Procedure

Step 1: Get Change Summary

git diff main...HEAD --stat
git log main..HEAD --oneline

Step 2: Review Each Changed File

For each file, check against the checklist.md.

Priority order:

1. Security concerns (auth, validation, secrets)
2. Database changes (migrations, schema)
3. API changes (breaking changes, rate limiting)
4. Logic correctness
5. Code style and patterns

Step 3: Check Test Coverage

# See what tests exist for changed files
git diff main...HEAD --name-only | grep -E '\.(ts|tsx)$' | while read f; do
  echo "=== $f ==="
  basename="${f%.*}"
  find packages/tests -name "*${basename##*/}*" 2>/dev/null
done

Step 4: Run Quality Checks

pnpm typecheck
pnpm lint
pnpm test:integration

Step 5: Generate Review Report

Output format:

• Flag any database schema changes for careful review
• Flag any auth/permission changes for security review
• If unsure about a change, ask for clarification
