1. input_validation: Zod schema? Parameterized queries?
2. edge_cases: null, empty, unicode, timeout?
3. error_handling: no empty catch? Logged with context?
4. duplication: same logic repeated?
5. complexity: functions < 30 lines?

Use quick_checks from quality skill for detection.

critical:

• No hardcoded secrets
• Auth tokens in httpOnly cookies
• Rate limiting
• HTTPS enforced

injection:

• SQL: parameterized only
• XSS: DOMPurify
• CSRF: tokens on state changes

verify:

• Tests exist BEFORE implementation?
• Edge cases covered?
• Assertions specific (not toBeTruthy)?
• Mocks at boundaries only?

red_flags:

• "Will add tests later"
• 100% coverage, weak assertions
• No error path testing

verify:

• Follows existing patterns?
• Interface stability?
• Modular boundaries?
• Dependency direction correct?
