Layered Clean Architecture: Standardizing Project Directory Structure to Prevent AI Boundary Violations

Wed, 05 Aug 2026 00:00:00 +0000

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.
