How does this skill help with code complexity?

It provides frameworks like KISS (Keep It Simple) and the Rule of Three to prevent over-engineering and ensure abstractions are only added when they solve concrete problems.

Is it compatible with frameworks like FastAPI or Flask?

Absolutely. While framework-agnostic, these patterns are specifically designed to organize logic within Python web frameworks and API services.

Can I use this for existing projects?

Yes, the skill includes specific patterns for refactoring complex codebases into clean, separated layers like Services and Repositories.

Does it focus on testing?

Yes, it emphasizes Dependency Injection and Composition Over Inheritance, which are critical patterns for creating highly testable and mockable Python units.

API 开发

Applies fundamental software design principles like KISS, SRP, and composition to build maintainable and scalable Python applications.

关于

This skill empowers Claude to architect Python systems using industry-standard design patterns and clean code principles. It provides actionable guidance on when to abstract, how to separate concerns into distinct layers (API, Service, Repository), and how to choose composition over inheritance for more testable code. By implementing patterns like the Rule of Three and Dependency Injection, it helps developers reduce technical debt and build modular systems that are easy to modify, test, and understand.
