Backend Development Guidelines

概要

This skill provides a comprehensive framework for building robust backend services, ensuring consistency across microservices through a strictly layered architecture of routes, controllers, services, and repositories. It automates the implementation of critical production-grade features including Zod validation, Sentry error tracking, Prisma database access, and unified configuration management. By enforcing these patterns, it helps developers maintain high code quality, improve testability, and accelerate the transition from legacy Express patterns to modern, scalable TypeScript architectures.
