How does this skill improve code testability?

By separating business rules from infrastructure (like databases or APIs) via interfaces and ports, it allows for easy mocking and unit testing of core logic.

What is the benefit of the 'Inward Dependency' rule?

It ensures that core business logic (Entities and Use Cases) remains independent of external changes in frameworks, databases, or UI components, reducing maintenance costs.

What specific architectures does this skill support?

This skill provides guidance and implementation patterns for Clean Architecture, Hexagonal Architecture (Ports and Adapters), and Domain-Driven Design (DDD).

Is this skill limited to a specific programming language?

While the provided examples use Python, the architectural principles and directory structures are universal and can be applied to any backend language like Java, Go, or Node.js.

Can I use this for refactoring existing projects?

Yes, it is specifically designed to help refactor monolithic or tightly coupled applications into more maintainable, loosely coupled architectures.

API開発

Implements industry-standard backend architectures like Clean Architecture, Hexagonal, and DDD to build maintainable and scalable systems.

The Backend Architecture Patterns skill empowers developers to implement robust, decoupled, and testable system designs using proven methodologies. By applying principles from Clean Architecture, Hexagonal Architecture (Ports and Adapters), and Domain-Driven Design (DDD), it helps separate core business logic from external frameworks and infrastructure. This skill is ideal for architecting complex new systems or refactoring legacy monoliths, providing standardized directory structures, defined dependency flows, and encapsulated domain models to ensure long-term codebase health.
