Are the generated DTOs mutable?

No, the skill generates immutable objects that are read-only after creation, preventing accidental state changes during data transfer.

What architectural patterns does this skill follow?

It follows DDD (Domain-Driven Design), CQRS, and Clean Architecture patterns, ensuring DTOs are placed in the correct layers like Presentation or Application.

Does this skill support the latest PHP features?

Yes, it is specifically optimized for PHP 8.4, utilizing readonly classes, constructor property promotion, and strict typing.

Can I generate tests alongside the DTOs?

Absolutely. The skill automatically generates unit tests following the standard project structure to verify serialization and validation logic.

API Development

Generates immutable, strictly typed Data Transfer Objects for PHP 8.4 applications following Clean Architecture and DDD principles.

The PHP DTO Architect skill automates the creation of production-grade Data Transfer Objects (DTOs) specifically designed for PHP 8.4 environments. It helps developers maintain strict layer boundaries in Hexagonal or Clean Architecture by generating immutable, validated objects for API requests, responses, commands, and infrastructure integrations. By handling the boilerplate of serialization, array conversion, and unit testing, this skill ensures that data moving through your application remains consistent, type-safe, and decoupled from domain entities.

Key Features

01Generates immutable PHP 8.4 readonly classes for maximum type safety.

02Includes automated generation of fromArray(), fromEntity(), and jsonSerialize() methods.

03Supports specialized DTO types for Requests, Responses, Commands, and Queries.

04Enforces standard directory structures for DDD and Hexagonal architectures.

05Produces comprehensive unit tests for every generated DTO class.
