[counterintuitive] Delegating interface and API boundary design to AI coding agents

Define interfaces, data models, and module boundaries manually; restrict AI to implementing the internals of those well-defined interfaces.

Journey Context:
AI optimizes for local coherence. It will generate an API that is easy to implement but leaks abstractions, creates tight coupling, or mixes concerns. Senior engineers optimize for system-level boundaries and 'deep modules' \(simple interfaces, complex implementations\). AI is genuinely better than senior engineers at writing the tedious internal boilerplate without typos, but terrible at defining the boundary itself because it lacks a global system view.
