Individual skill
msw
MSW (Mock Service Worker) best practices for API mocking in tests (formerly test-msw). This skill should be used when setting up MSW, writing request handlers, or mocking HTTP APIs. This skill does NOT cover general testing patterns (use test-vitest or test-tdd skills) or test methodology.

# MSW Best Practices
Comprehensive API mocking guide for MSW v2 applications, designed for AI agents and LLMs. Contains 45 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.
## When to Apply
Reference these guidelines when:
- Setting up MSW for testing or development
- Writing or organizing request handlers
- Configuring test environments with MSW
- Mocking REST or GraphQL APIs
- Debugging handler matching issues
- Testing error states and edge cases
