Enforces strict layer separation and Clean Architecture patterns in FastAPI projects through automated, blocking validation.

The Backend Architecture Enforcer is a specialized Claude Code skill designed to maintain codebase integrity by strictly enforcing the Router-Service-Repository pattern in FastAPI applications. It provides real-time, blocking validation to prevent architectural drift, such as database logic leaking into route handlers or HTTP exceptions appearing in business logic layers. By automating the enforcement of dependency injection patterns, async consistency, and standardized naming conventions, it ensures that backend services remain modular, highly testable, and production-ready.
