How does this skill help with Clean Architecture?

It provides structural templates and logic guidance for organizing code into distinct layers (Entities, Use Cases, Adapters) where dependencies only point inward.

Can I use this skill to refactor existing legacy projects?

Yes, this skill is specifically designed to help identify tight coupling and provide a step-by-step roadmap for refactoring into decoupled, maintainable patterns.

What is the benefit of using Hexagonal Architecture with this skill?

It helps you define clear Ports (interfaces) and Adapters (implementations), allowing you to swap technologies like databases or APIs without touching core business logic.

Does it support specific programming languages?

While the architectural concepts are language-agnostic, the skill provides implementation patterns and examples compatible with major backend languages like Python, Java, and Go.

API開発

Implements robust architectural frameworks like Clean Architecture, Hexagonal, and Domain-Driven Design for scalable backend systems.

This skill empowers Claude to architect complex backend systems using industry-standard patterns that prioritize long-term maintainability and testability. By enforcing strict separation of concerns through Clean Architecture layers and Hexagonal Ports and Adapters, it ensures that core business logic remains independent of frameworks, databases, and external UI. Whether you are refactoring a legacy monolith or designing a new microservice from scratch, this skill provides the structural blueprints, implementation patterns, and directory standards needed to build a professional, decoupled codebase.
