Production Backend Development Guidelines
Enforces strict architectural patterns and reliability standards for production-grade Node.js and Express backend services.
This skill equips Claude with the expertise of a senior backend engineer to build predictable and maintainable systems using a strict layered architecture. It mandates a clear separation of concerns across routes, controllers, services, and repositories while integrating essential tools like Zod for validation, Prisma for database access, and Sentry for observability. By calculating a Backend Feasibility & Risk Index (BFRI) and enforcing non-negotiable coding doctrines, this skill ensures that backend features are built for scale, testability, and high reliability in production environments.
