Writes fast, isolated unit and integration tests with Vitest. Use when each test must run on file-save without shared state — `vi.mock()` for external deps, `vi.spyOn()` for call monitoring, AAA structure, and edge-case coverage for null/undefined/boundary inputs.

基于 SOC 职业分类
Designs stable, well-documented APIs and module interfaces. Use when creating REST/GraphQL endpoints, defining contracts between modules, or changing public interfaces. The wire-format SSOT — response envelope, HTTP status codes, validation taxonomy, payload naming — lives in `.agents/rules/api-conventions.md`; this skill shows authors how to apply it.
Tests in real browsers. Use when building or debugging anything that runs in a browser. Use when you need to inspect the DOM, capture console errors, analyze network requests, profile performance, or verify visual output with real runtime data via Chrome DevTools MCP.
Conducts multi-axis code review and runs the disciplined post-green refactor pass. Use before merging any change, when reviewing code written by yourself, another agent, or a human, or when the opt-in `delivery.refactorStage` checkpoint asks for a behaviour-preserving CRAP/duplication pass after the suite is green.
Guides systematic root-cause debugging. Use when tests fail, builds break, behavior doesn't match expectations, or you encounter any unexpected error. Use when you need a systematic approach to finding and fixing the root cause rather than guessing.
Records decisions and documentation. Use when making architectural decisions, changing public APIs, shipping features, or when you need to record context that future engineers and agents will need to understand the codebase.
Structures git workflow practices. Use when making any code change. Use when committing, branching, resolving conflicts, or when you need to organize work across multiple parallel streams.
