How does this skill improve code testability?

By enforcing dependency inversion and separating business logic from infrastructure, it allows you to test core logic without needing a UI, database, or external APIs.

Can this skill help with existing legacy code?

Yes, it is designed to assist in refactoring tightly coupled monolithic applications into more maintainable, loosely coupled structures.

Which architecture patterns does this skill support?

This skill focuses on Clean Architecture, Hexagonal Architecture (Ports and Adapters), and Domain-Driven Design (DDD) principles.

Is this skill language-specific?

While the architectural concepts are universal, the skill provides implementation patterns and examples suitable for various backend languages including Python, Java, and Node.js.

API Development

Implements professional backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design for scalable systems.

About

The Architecture Patterns skill enables Claude to architect and refactor backend systems using industry-standard methodologies. It provides structured guidance on implementing Clean Architecture for dependency management, Hexagonal Architecture (Ports and Adapters) for technology-agnostic cores, and Domain-Driven Design (DDD) for managing complex business logic. This skill is essential for developers who need to build maintainable, testable, and loosely coupled systems that can evolve alongside changing business requirements and technology stacks.
