When to use this skill

Use this skill whenever the user wants to:

• Structure an application following Clean Architecture layers (Entities, Use Cases, Interface Adapters, Frameworks)
• Enforce the dependency rule: inner layers never depend on outer layers
• Organize project packages and define clear test boundaries
• Combine Clean Architecture with Domain-Driven Design patterns

How to use this skill

Workflow

1. Define Entities (innermost layer) containing enterprise-wide business rules
2. Define Use Cases (application layer) containing application-specific business logic
3. Create Interface Adapters (presenters, gateways) that convert data between layers
4. Implement Frameworks (outermost layer) for web, database, and UI concerns
