Does this skill support modern PHP 8.4 features?

Yes, it is specifically optimized for PHP 8.4, utilizing modern syntax such as readonly classes, property promotion, and strict type hinting.

Can I generate tests automatically with this skill?

Yes, the skill generates unit tests for every concrete visitor implementation and verifies that elements correctly implement the double-dispatch accept method.

Where does the skill place the generated files?

The skill follows clean architecture conventions, placing interfaces and domain visitors in the Domain layer and application-specific visitors in the Application layer.

How does the Visitor pattern help with the Open/Closed Principle?

It allows you to add new operations (Visitors) to existing object structures (Elements) without modifying the code of those elements, making the system open for extension but closed for modification.

Developer Tools

Implements the Visitor design pattern for PHP 8.4 applications to add new operations to object structures without modifying existing classes.

This skill automates the creation of the Visitor design pattern infrastructure within PHP 8.4 projects, facilitating clean architecture and SOLID principles. It generates high-quality, type-safe code including visitor interfaces, multiple concrete visitor implementations, and visitable elements with double-dispatch support. By decoupling algorithms from the object structures they operate on, developers can extend functionality—such as adding export formats, price calculations, or validation logic—without altering core domain classes, all while ensuring full test coverage through generated unit tests.
