A deep module in software architecture is a module with a simple interface that hides complex implementation details. This design approach maximizes information hiding, simplifying usage while encapsulating low-level complexity behind a minimal API.

To design a deep module with an anti-corruption layer and bounded context, define a simple interface that isolates internal complexity from external dependencies. This ensures the bounded context remains protected and the module maintains a deep, hideable implementation.

To review an existing module for deep module principles, evaluate its interface simplicity, boundary definitions, performance, and security against a detailed checklist. This process identifies shallow areas where information hiding is insufficient.

You should use an anti-corruption layer in bounded contexts when integrating external subsystems that have different domain models. It isolates external complexity, preserving the integrity of your deep module interfaces and preventing domain logic leakage.

Yes, this deep module design approach works specifically for module-level architecture reviews. It provides a framework to evaluate interface simplicity, information hiding, and boundary definitions to ensure low-level complexity is properly encapsulated.

Your module interface exposes too much implementation detail because it lacks deep module design principles like information hiding. Applying an anti-corruption layer and bounded context boundaries will simplify the interface and hide low-level complexity.
