What architectural patterns does this skill support?

It primarily supports Clean Architecture and Domain-Driven Design (DDD) to ensure a clear separation between business logic and infrastructure concerns.

Does this skill work for both frontend and backend?

While it focuses on backend concepts like entities and use cases, its principles of clean code, naming conventions, and library usage apply to any complex software project.

What file size limits does this skill recommend?

The skill encourages keeping functions under 50-80 lines and files under 200 lines to ensure high modularity and easier testing.

Can this skill help with code refactoring?

Yes, it specializes in decomposing large components, removing deeply nested conditions, and renaming generic 'utils' files into domain-specific modules.

How does the 'Library-First' approach work?

It instructs Claude to prioritize searching for existing npm packages, SaaS solutions, or established APIs before writing custom code to reduce long-term maintenance overhead.

API開発

Implements high-quality software design patterns using Clean Architecture and Domain-Driven Design (DDD) principles.

概要

This skill elevates Claude Code's development capabilities by enforcing Clean Architecture and Domain-Driven Design (DDD) standards. It guides the creation of modular, maintainable codebases by prioritizing a 'Library-First' approach, discouraging 'Not Invented Here' syndrome, and enforcing strict naming conventions. By focusing on the separation of concerns between domain logic and infrastructure, it ensures that applications remain scalable and testable while avoiding common anti-patterns like generic utility files, deeply nested conditions, and mixed responsibilities.
