How does this help with unit testing in PHP?

By forcing the move from static calls and hard-coded 'new' instances to injected interfaces, it ensures that every dependency can be easily mocked using tools like PHPUnit or Mockery.

Does this skill support modern PHP features?

Yes, it is optimized for modern PHP standards, specifically focusing on constructor property promotion and interface-driven design.

What common PHP anti-patterns does this skill detect?

It identifies the Service Locator pattern, direct usage of 'new' for services, static method calls, use of superglobals like $_SESSION, and direct getenv() calls in business logic.

Can it distinguish between Value Objects and Services?

Yes, the skill includes logic to ignore 'acceptable' uses of the 'new' keyword, such as instantiating Value Objects (DTOs), Exceptions, and instances inside Factory classes.

セキュリティとテスト

Analyzes PHP codebases to identify and resolve dependency injection anti-patterns and architectural violations.

The PHP Dependency Injection Auditor is a specialized skill for Claude Code designed to enforce high-quality architectural standards in PHP applications. It scans your source code for common technical debt such as the 'new' keyword in business logic, the Service Locator anti-pattern, static method calls, and hidden dependencies via superglobals or environment variables. By identifying these issues and providing clear refactoring paths toward interface-driven constructor injection, the skill helps developers create highly testable, decoupled, and maintainable systems that adhere to SOLID and Clean Architecture principles.
