clean-architecture

To enforce dependency direction in clean architecture, you codify architectural rules that prevent leakage between layers, keeping dependencies pointing inward toward the domain. This Skill provides boundary definitions and verification checks to maintain stable, testable codebases.

The best way to separate domain and infrastructure layers is through disciplined layering that isolates business rules in domain entities. This Skill provides templates and guidance to clearly divide domain, application, infrastructure, and interface responsibilities.

To isolate use cases without leaking business logic, you orchestrate use-cases to coordinate entities while keeping business rules encapsulated in domain entities. This Skill codifies use-case isolation guidelines to ensure application logic remains separate from infrastructure.

Yes, clean architecture works for testing across complex domains by enforcing boundary definitions and dependency rules that prevent layer leakage. This approach promotes stable, testable codebases by isolating business rules from external interfaces and infrastructure concerns.

To start applying clean architecture boundaries to an existing codebase, review your components, map them to architectural boundaries, and apply the provided dependency rules and use-case guidelines. This Skill includes checklists and reference material to enforce consistent decisions.

You should reconsider clean architecture layering when your project lacks clear domain complexity or when strict boundary definitions would introduce unnecessary overhead. The architectural rules and verification checks are designed for teams needing maintainability across complex domains, services, and interfaces.
