Identifying shallow modules involves analyzing codebases where logic is fragmented across small, tightly-coupled units lacking clear seams. Deepening these modules concentrates complexity behind simple interfaces, improving testability and maintainability.

Refactoring tightly coupled code involves identifying shallow modules and consolidating their fragmented logic into deep components. This process establishes clear architectural seams and adapters to isolate complexity and improve testability.

You need to deepen modules when logic is fragmented across many small, pass-through units, making the codebase difficult to navigate or test. Deepening consolidates complexity into high-leverage components with clean seams.

Yes, this approach applies directly to complex codebases where logic is fragmented across tightly-coupled units lacking clear seams. It transforms shallow modules into deep, maintainable components using defined architectural vocabulary.

The best way to design interfaces for refactored modules is using parallel sub-agent patterns to explore and compare multiple architectural designs. This ensures the resulting deep module has a clean, well-defined seam.

Your codebase lacks clear seams because logic is spread across many shallow, tightly-coupled pass-through modules. Consolidating this fragmented logic into deep modules using a defined architectural vocabulary establishes proper boundaries.
