Separation of Concerns Pattern

关于

This skill provides a comprehensive architectural framework for building maintainable and scalable systems through strict component isolation. By guiding the implementation of the Orchestrator pattern, it helps developers separate CLI or API presentation logic from core business rules, facilitating fast unit testing via dependency injection and ensuring that changes in external dependencies remain localized. It is particularly useful for refactoring tangled codebases into clean, professional structures where every component has a single, well-defined responsibility.
