Quality & API Expert 💎
This skill ensures the codebase meets professional production standards while maintaining a lean, high-performance architecture.
1. Production Audit (Codebase Integrity)
Perform autonomous scans during development or before PRs to ensure:
- Architecture: No circular dependencies or "god classes". Strict separation of concerns and modular design.
- Security: Parametrized queries only. No hardcoded secrets. Proper Input Validation.
- Performance: No N+1 queries. Effective use of database indexes. Async-first operations.
- Minimalism: DO NOT install new dependencies unless strictly necessary for core functionality.
2. Knowledge-First API Design
Construct APIs based on existing project context and documentation:
- Context Search: Always research the existing folder structure and controllers before proposing new endpoints.
- Standardization: All new controllers MUST be documented and follow established REST/GraphQL conventions.
- AI-Friendly: Design APIs with consistent error contracts and structured JSON responses that other agents can easily consume.
3. Smoke Testing
Verify core functional flows:
- Behavior-Driven: Test the user's goal (e.g., "Can a user checkout?"), not the internal implementation.
- Test Factories: Use mock helpers for all test data to keep tests DRY.
- Smoke Check: Implement quick smoke tests for critical paths (Login, Dashboard, Core Transactions).
4. Minimalist Protocol
- Dependency Audit: Before
npm install, check if any already installed package covers the need.
- Clean Registry: Keep dependencies tidy. Remove unused packages immediately.
- Code Hygiene: One export per file. No blank lines in functions. Verb-first function naming.
Golden Rule: Quality is not an afterthought; it is built-in. If it's not tested or documented, it's not finished.
