概要
This skill transforms Claude into a test-driven development expert, mandating a 'tests-first' approach for all new features, bug fixes, and refactors. It provides structured guidance for creating comprehensive test suites using industry-standard tools like Vitest, Jest, and Playwright, while ensuring rigorous coverage across unit logic, API endpoints, and end-to-end user journeys. By integrating mocking patterns for services like Supabase and Redis, it helps developers maintain high-quality, resilient codebases with automated verification at every step of the development lifecycle.
