Backend Development Guidelines
Enforces strict architectural patterns and reliability standards for production-grade Node.js and Express backend services.
This skill transforms Claude into a senior backend engineer, providing a robust framework for building predictable and observable systems. It mandates a layered architecture (Routes-Controllers-Services-Repositories), strictly separates concerns, and ensures all external inputs are validated with Zod. By implementing the Backend Feasibility & Risk Index (BFRI) and requiring first-class observability through Sentry, it guides developers through complex refactors, API design, and database access patterns with Prisma while maintaining high testability and operational safety.
