Clean Architecture & DDD Patterns
Implements maintainable, decoupled backend systems using SOLID principles, hexagonal architecture, and Domain-Driven Design (DDD).
The Clean Architecture skill empowers Claude with the structural expertise needed to build production-grade, testable backends. By enforcing hexagonal architecture (ports and adapters) and tactical DDD patterns, it ensures that core domain logic remains isolated from external frameworks like FastAPI or specific database implementations. The skill includes automated hooks to validate import directions and layer boundaries, helping developers avoid common pitfalls like infrastructure leakage and tight coupling while maintaining a standardized, scalable directory structure.
