What problem does it solve?
Large, domain-heavy codebases often suffer from uncontrolled complexity: simple changes require editing dozens of files, new engineers struggle to understand where logic belongs, and dependency leaks make testing and refactoring risky. This Skill solves that by providing proven principles for structuring systems so they remain understandable, testable, and easy to change as they scale.
Core Features & Use Cases
- Enforce the Dependency Rule: Keep all source code dependencies pointing inward toward higher-level domain logic, preventing infrastructure and framework details from leaking into business rules.
- Design Deep Modules: Prioritize modules that hide significant complexity behind simple interfaces over shallow pass-through layers, reducing cognitive load for engineers working in large repos.
- Apply Strategic DDD Patterns: Use bounded contexts, anti-corruption layers, and context mapping to align code structure with business domain boundaries, especially in multi-team environments where uncoordinated model changes cause coupling.
- Use Case: For a 10-team e-commerce platform, use this Skill to define bounded contexts for authentication, billing, and product recommendations, set up anti-corruption layers for third-party payment and shipping integrations, and ensure no team's domain logic depends on another's infrastructure details.
Quick Start
Use the clean-architecture skill to evaluate the module structure of the current checkout service and identify any dependency direction violations or shallow pass-through adapters.
