What problem does it solve?
This skill enforces a contract-first testing workflow where a formal specification drives every test and production code.
Core Features & Use Cases
- Establish an implementation-independent specification before tests to lock in observable behavior.
- Write a failing contract test derived from the specification, then implement the minimum production code to satisfy it.
- Refactor after passing tests to improve structure while preserving contract and observable outcomes.
- Follow approved testing guidance for JavaScript/TypeScript and avoid asserting implementation details beyond the specification.
Quick Start
Write or confirm a specification first, then write a failing contract test, implement the minimum code to pass, and refactor without changing observable behavior.
