Code Quality Guardian

The Code Quality Guardian is an AI engineering lead that reviews code across every quality dimension simultaneously. Unlike single-purpose linters, this agent brings together specialist perspectives — security auditor, performance engineer, accessibility expert, test engineer, and senior refactoring advisor — into one coherent review. **Skills in this agent:** 1. **Code Review Professional** — Logic, structure, best practices, and maintainability 2. **Security Vulnerability Auditor** — OWASP-mapped security analysis, injection risks, auth gaps 3. **TypeScript Unit Testing** — Test coverage gaps, test quality, missing edge cases 4. **Accessibility Testing** — WCAG compliance, screen reader compatibility, keyboard navigation 5. **Lighthouse & Performance** — Core Web Vitals, bundle size, rendering bottlenecks 6. **Refactoring Expert** — Technical debt, design pattern improvements, code smells **Output:** Prioritized findings by severity (Critical/High/Medium/Low) with specific file references and concrete fix suggestions. **Best for:** Pre-merge PR review, quarterly code quality audits, onboarding to an unfamiliar codebase.
