Can I customize the file locations?

The skill follows a standard directory structure (src/Entity to src/Out) but allows for namespace customization to fit your specific project architecture.

Does this skill require an existing entity to work?

Yes, the skill validates that a corresponding entity exists in the src/Entity/ directory before it proceeds with generating the Out DTO.

Which design patterns does the generated code use?

It follows the Static Factory pattern and utilizes PHP's 'readonly' and 'final' keywords to ensure strict immutability and prevent unintended inheritance.

What is an 'Out' class in this context?

An 'Out' class is an immutable Data Transfer Object (DTO) specifically designed to represent data being sent out of your application, ensuring internal entity details are encapsulated.

API Development

Generates immutable Data Transfer Objects (DTOs) from entities to create a clean anti-corruption layer for data output.

About

The Immutable Output DTO Generator (make-out) is a specialized skill for Claude Code that automates the creation of 'Out' classes—robust DTOs designed to represent an entity's output data safely. By implementing a final readonly structure with a private constructor and a static factory method, it enforces immutability and acts as an anti-corruption layer between your core domain model and external consumers. This skill is particularly useful for developers who want to ensure that internal entity changes do not accidentally break public API contracts or leak sensitive internal states.

Key Features

Generates final readonly PHP classes for maximum type safety and immutability
Implements a private constructor with a static new() factory method
Supports customizable namespaces and naming conventions
Automates the extraction of properties from existing entities in src/Entity
Enforces clean architecture principles by separating domain and presentation layers
5 GitHub stars

Use Cases

Creating a secure and standardized output layer for REST or GraphQL APIs
Rapidly scaffolding boilerplate code for new data response objects
Implementing an anti-corruption layer to protect internal domain models
