Clean Architecture Skill

Validate, implement, and maintain Clean Architecture patterns across the full stack. This skill covers architectural conformance checking, layer boundary enforcement, and guided refactoring.

See references/layer-examples.md for full code examples across all frameworks.

Architecture Layers

Layer 1: Entities (Domain Core)

The innermost layer. Pure business logic with zero framework dependencies.

• Rails: Models with domain logic only (backend/app/models/), value objects (backend/app/values/)
• React Native: Pure TypeScript interfaces and domain functions (mobile/src/domain/)
• Vite SPA: Pure TypeScript types (web/src/domain/)
• Next.js: Shared TypeScript types (next/src/domain/)
