Reduce Go code complexity by enforcing a bounded data flow with a strict three-layer architecture (Handler → Service → Repository). This structure limits indirection, keeps data flow traceable, and clarifies code readability before implementation.

The best way to structure Go features for maintainability is organizing them into a three-layer architecture: Handler, Service, and Repository. This enforces clear responsibilities, single-package boundaries, and explicit interfaces to minimize cognitive load.

Evaluate Go code review trade-offs by applying indirection budgeting and checking code locality. Ensure the implementation adheres to concise interfaces and explicit documentation of architectural decisions to maintain readability and bounded data flow.

Yes, you can use this model for onboarding developers to a Go codebase. It provides fast evaluation of feature design trade-offs and relies on a strict Handler → Service → Repository structure to make data flow traceable and readable.

Go codebases suffer high cognitive load and unclear data flow due to excessive indirection and lack of bounded architectural layers. Applying single-package boundaries, concise interfaces, and a Handler → Service → Repository pattern resolves this.
