Does this skill work with any programming language?

This skill is currently optimized for PHP projects, specifically those following standard entity and namespace structures like those found in Symfony or Laravel.

What is an 'Invalide' class?

It is a specialized class designed to handle business-level exceptions for a specific entity, keeping your domain logic clean, expressive, and separated from infrastructure.

How does this help with the fail-fast principle?

It provides a standardized, easy-to-invoke structure for throwing context-rich exceptions as soon as a business rule is violated, preventing the application from entering an inconsistent state.

Why do the factory methods start with 'car'?

The 'car' prefix is a specific naming convention used by this framework to distinguish factory methods that specifically return exceptions related to business constraints.

Developer Tools

Generates specialized business exception classes with factory methods to enforce domain invariants and fail-fast logic.

About

This skill automates the creation of 'Invalide' classes, a pattern used to centralize and standardize domain-specific exceptions for PHP entities. It enforces architectural best practices such as final classes, private constructors, and static factory methods (prefixed with 'car') for expressive error handling. By verifying entity existence and following a strict template, it helps developers implement robust error management that remains consistent across the codebase, ensuring that business rules are validated efficiently and failures are handled with maximum context.
