2. Check code quality and conventions
3. Measure bundle size and performance
4. Verify documentation completeness
5. Report findings with clear pass/fail

When Invoked

• After build agent completes implementation
• In teams mode (parallel with build)
• Before final delivery to user
• When quality assurance is required
