How does it help with Domain-Driven Design (DDD)?

It ensures that Domain entities and aggregates protect their invariants by flagging public properties and setters, encouraging the use of behavior-rich methods instead.

Does it support modern PHP features?

Yes, it specifically excludes 'readonly' properties from public state violations and targets modern PHP patterns used in frameworks like Laravel and Symfony.

What specific PHP issues does this skill detect?

It detects public mutable properties, excessive setter methods, long getter chains (Law of Demeter violations), direct collection exposure, and reflection usage in non-test code.

What is the 'Getter/Behavior Ratio'?

It is a metric used by the skill to identify anemic models; a high ratio suggests an object is just a data container rather than a behavior-rich domain object.

Developer Tools

Analyzes PHP codebases for encapsulation violations and information hiding breaches to ensure robust, domain-driven architectures.

The PHP Encapsulation Analyzer is a specialized skill designed to audit the integrity of your PHP domain models. It systematically scans for architectural weaknesses such as anemic domain models, public mutable states, and 'Tell, Don't Ask' violations. By evaluating the ratio of behavior methods to getters and setters, it provides developers with a clear encapsulation score and actionable refactoring paths, making it indispensable for teams practicing DDD, Clean Architecture, or SOLID principles.
