Is it limited to Hexagonal Architecture?

While focused on Hexagonal and Clean Architecture, it also covers related concepts like DDD, CQRS, SOLID, GRASP, and PSR standards.

How do I use this during a code review?

You can ask Claude to audit a specific directory against the included checklists to ensure that business logic is isolated and that dependencies point inward correctly.

Does it support modern PHP features?

Yes, it includes implementation patterns specifically optimized for PHP 8.4, including readonly classes, constructor promotion, and strict typing.

Can it detect architectural violations?

Yes, it includes checklists and reference guides to help Claude identify when inner layers (like Domain) are incorrectly importing outer layers (like Infrastructure or Frameworks).

What is the PHP Clean Architecture skill?

It is a specialized knowledge base for Claude Code that provides patterns, antipatterns, and implementation guidelines for building decoupled and maintainable PHP applications.

API Development

Provides expert architectural guidance and PHP implementation patterns for Clean and Hexagonal Architecture.

This skill equips Claude with a comprehensive knowledge base for auditing and implementing Clean Architecture and Hexagonal (Ports & Adapters) patterns within PHP projects. It offers standardized checklists for Domain and Application layers, identifies common architectural violations like framework leakage into the core, and provides modern PHP 8.4 code examples for Use Cases, DTOs, and Port interfaces. It is an essential companion for developers aiming to maintain decoupled, testable, and highly maintainable codebases using DDD, CQRS, and SOLID principles.
