Layered Clean Architecture: Standardizing Project Directory Structure to Prevent AI Boundary Violations
AI writing code has one very common problem: It knows how a feature should be implemented, but doesn’t necessarily know where the code should go. For example, if you tell AI: “Add a delete Agent feature.” Without a clear project structure, it might directly, inside the API endpoint: query the database, evaluate business rules, clear the cache… The feature might work quickly. But as AI writes code this way again and again, the project will eventually become: Business logic inside the API Database operations inside Services Business judgments inside Repositories Utility classes referenced everywhere At this point, we need another very fundamental yet extremely important architectural concept: Layering. ...
