Encapsulation Analyzer
Overview
This skill analyzes PHP codebases for encapsulation violations — situations where internal state is exposed, getters/setters replace behavior, or the "Tell, Don't Ask" principle is violated.
Encapsulation Principles
| Principle | Description | Violation Indicator |
|---|---|---|
| Information Hiding | Internal state not exposed | Public properties, many getters |
| Tell Don't Ask | Objects perform actions, not expose data | Getter chains, external decisions |
| Behavioral Richness | Objects have behavior, not just data | Anemic domain model |
| Invariant Protection | State changes validate constraints | Public setters without validation |
