Guides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Use when creating REST or GraphQL endpoints, defining type contracts between modules, or establishing boundaries between frontend and backend.
Prevent commits that skip pre-commit hooks (--no-verify, -n). Auto-loads when git commit with bypass flags is attempted. Triggers: commit --no-verify, git commit -n, git push --no-verify.
Explore ideas before implementation, design features, make architecture decisions, and validate approaches. Use when: brainstorm, explore options, design, what approach, how should we, ideas, before building.
Tests in real browsers via Chrome DevTools MCP. 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. Requires the chrome-devtools MCP server to be configured.
Automates CI/CD pipeline setup. Use when setting up or modifying build and deployment pipelines.
Conducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch.
Shared vocabulary for designing deep modules. Use when: design a module interface, decide where a seam goes, make code more testable, reduce coupling, evaluate if a module is too shallow, or another skill needs the deep-module vocabulary.
