Activation Contract

Use this skill when asked to evaluate or improve Java object-oriented design using SOLID, cohesion, coupling, composition, inheritance, interfaces, and dependency direction.

Do not use this skill for simple naming/style cleanup, pattern shopping, framework wiring only, or non-Java code.

Responsibility

This skill teaches Java SOLID design review. It does not call other skills, prescribe interfaces everywhere, or force pattern usage.

Required Context

• Classes/interfaces involved.
• Change scenario or pain point.
• Public API compatibility constraints.
• Existing dependency direction and lifecycle ownership.
