How does this skill help with backend maintainability?

It enforces the separation of concerns by ensuring that domain logic never depends on infrastructure, frameworks, or external libraries, making the system easier to test and modify.

Is this skill specific to FastAPI?

While the examples and hooks are optimized for Python and FastAPI, the underlying principles of SOLID and Hexagonal Architecture can be applied to any backend framework.

Can this skill validate my code automatically?

Yes, it includes post-tool-use hooks that trigger validators for backend layers and import directions whenever Claude writes or edits code.

What is the difference between an Entity and a Value Object in this context?

The skill defines Entities based on identity (UUIDs) and Value Objects based on structural equality and immutability, following standard DDD tactical patterns.

API 开发

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.
