Clean Architecture

@marcioaltoe/claude-craftkit-architecture-design-clean-architecture

Clean Architecture principles including layered architecture, dependency rule, and domain-driven design patterns. **ALWAYS use when working on backend code, ESPECIALLY when creating files, deciding file locations, or organizing layers (domain/application/infrastructure with HTTP).** Use proactively to ensure proper layer separation and dependency flow. Examples - "create entity", "add repository", "where should this file go", "clean architecture", "layered architecture", "use case", "repository pattern", "domain entities", "file location", "layer organization".
