概要
This skill enables developers to implement new API features through a rigorous Test-Driven Development (TDD) process specifically tailored for NestJS applications using the @lenne.tech/nest-server framework. By following a structured seven-step workflow, it ensures that every requirement is first captured in comprehensive story tests before any production code is written. It enforces an 'API-First' testing philosophy—verifying functionality through REST or GraphQL interfaces rather than direct service calls—to guarantee that security layers, guards, and decorators are correctly validated. The skill manages the entire lifecycle from initial story analysis to final security reviews, delivering high-quality, maintainable, and production-ready code.
