Skill UI

Generates Vitest tests in JavaScript/TypeScript with Vite-native speed. Covers Jest-compatible APIs, vi.mock mocking, spies, fake timers, snapshots, React component tests, in-source testing, and vitest.config setup.

Generates comprehensive technical documentation pages with evidence-based depth, including Mermaid diagrams, citations, and VitePress frontmatter. Ideal for documenting components, systems, or features with traceable code paths.

Answer repository questions grounded entirely in source code evidence. Searches and reads relevant files, then synthesizes answers with inline citations. Useful for understanding specific files, functions, or components, and for answering how or where questions about the codebase.

This skill generates championship-grade test suites for any project using the WJTTC methodology. It analyzes the codebase, classifies components, and scaffolds executable test files. It emphasizes pre-defined test plans, inline testing, and two-layer testing architecture to ensure high code quality and signal integrity in CI/CD pipelines.

This skill enables developers to create Zustand stores following established patterns with proper TypeScript types and middleware. It provides templates for separating state and actions, using individual selectors, and subscribing outside React components. Ideal for React frontend development projects requiring robust state management solutions with type safety and best practices.
