Can I use this for existing projects?

Yes, this skill is specifically designed to help refactor legacy or monolithic applications into more maintainable and loosely coupled architectures.

Is this skill specific to a particular framework?

No, the patterns provided are framework-agnostic, though the examples demonstrate how to integrate with modern tools like FastAPI and asyncpg.

What architectures does this skill support?

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

Does it provide code examples?

Yes, it includes detailed implementation examples in Python covering entities, repositories, use cases, adapters, and value objects.

How does this help with software testing?

By enforcing dependency inversion and using ports/interfaces, the skill makes it easy to mock external dependencies like databases and APIs, enabling high-coverage unit testing.

API Development

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

About

This skill empowers developers to transition from monolithic, tightly coupled codebases to modular, testable, and maintainable architectures. By providing templates and guidance for Clean Architecture, Hexagonal (Ports and Adapters), and DDD tactical patterns, it ensures that core business logic remains independent of frameworks, databases, and external UI concerns. It is an essential tool for architects and senior developers looking to establish standardized directory structures and dependency flows that facilitate long-term system evolution and easier testing.
