Frontend-Backend Separation: Constraining AI's Division of Labor to Avoid Interface Coupling and Responsibility Confusion

AI is very good at writing code. But without clear architectural boundaries, it can easily develop one problem:

Wherever it’s convenient to write code, that’s where the code gets written.

Business rules that should belong to the backend might end up stuffed into Vue pages. API calls that should be uniformly encapsulated might scatter across various components. The frontend might even “invent” its own data structures inconsistent with the backend, based on page requirements.

The code might run, but the project gradually loses its boundaries.

And frontend-backend separation is the first important boundary to draw for AI.
