Fix shallow, tightly-coupled module boundaries by scanning for modules that delegate without adding value, then proposing how to deepen them into coherent interfaces that hide internal complexity.

Reduce coupling by analyzing shallow modules and proposing deeper module boundaries, applying dependency classification to align structural design choices with a targeted testing strategy.

Dependency classification for testability works by categorizing dependencies into in-process, local-substitutable, ports & adapters, and mock types to align architectural design choices with your testing strategy.

Create a testing plan when refactoring module boundaries by recommending boundary tests to add and identifying shallow tests to remove, following a replace-not-layer philosophy to reduce integration risk.

Yes, you can analyze an Angular or TypeScript codebase to identify small modules that bounce logic across boundaries, producing a consolidated interface design and a boundary-test plan.

You need an architecture review when shallow module boundaries create integration risk, make navigation difficult, or cause tightly-coupled modules to produce brittle seams that hinder maintainability.
