Can this skill help detect architectural violations in existing code?

Yes, it includes a reference for common violations such as 'skipping layers' (e.g., a Controller calling the Database directly) or 'upward dependencies' where the domain layer relies on application logic.

How does it handle Domain-Driven Design (DDD)?

It provides specific patterns for rich Domain Entities, Value Objects, and Repository interfaces that keep business logic pure and decoupled from technical infrastructure like Doctrine or Eloquent.

Is this skill specific to a certain PHP version?

While the architectural principles are universal, the provided code patterns and examples are optimized for modern PHP 8.4+ features like readonly classes, constructor promotion, and enums.

What is the primary rule of this Layered Architecture skill?

The core rule is that each layer (Presentation, Application, Domain, Infrastructure) may only communicate with the layer directly below it to ensure strict separation of concerns and maintainability.

API Development

Enforces architectural integrity and provides implementation patterns for N-tier layered systems in PHP applications.

This skill equips Claude with a comprehensive knowledge base for implementing and auditing Layered Architecture (N-Tier) within PHP environments. It provides standardized patterns for Presentation, Application, Domain, and Infrastructure layers, ensuring strict separation of concerns and adherence to dependency rules. Whether you are refactoring a legacy codebase, building a new DDD-inspired system, or performing an architectural audit, this skill helps identify violations like 'fat controllers' or 'skipping layers' while providing PHP 8.4-ready code templates for DTOs, services, and repositories.

Key Features

01Strict communication rules defining how layers interact and exchange data.

02Automated architectural audits to detect layer violations and upward dependencies.

03Detailed checklists for verifying layer-specific responsibilities and thin controllers.

04Identification of common antipatterns like anemic services or business logic in repositories.

05Reference patterns for PHP 8.4 Entities, DTOs, and Repository interfaces.

Use Cases

01Refactoring monolithic PHP controllers into distinct Application and Domain layers.

02Performing code reviews to ensure infrastructure code doesn't leak into the Domain layer.

03Bootstrapping new PHP modules with standardized DDD and Layered Architecture structures.
