Implements production-ready code using rigorous TDD/ATDD principles and the Red-Green-Refactor cycle.
The TDD Implementation skill automates a structured Test-Driven Development workflow within Claude Code, transforming technical specifications into verified software. Following the London School (Outside-In) approach, it guides the development process by establishing structural invariants and testability gates before proceeding to the core Red-Green-Refactor cycle. This ensures that interfaces are naturally discovered through testing, resulting in highly decoupled, maintainable, and verifiable architectures that adhere strictly to pre-defined requirements in tdd-spec.md.
