Implements type-safe, test-driven TypeScript features following strict dependency injection patterns.
This skill equips Claude with a rigorous framework for TypeScript development, prioritizing type safety and behavior-driven testing. It enforces a no-mocking policy, favoring dependency injection to ensure code is robust and maintainable. By integrating with specification workflows and automated verification tools like Vitest and ESLint, it ensures every implementation meets professional standards and architectural requirements while preventing common pitfalls like deep relative imports or unaddressed type errors.
