What does design system AI readiness mean, anyway?

Sean Voisen (emphasis mine):

This means specifically telling the agent to actually use the intended design system, use these components in such and such a way, use these colors for these purposes and not other purposes, always lay out elements in this fashion using these pre-defined spacing tokens, avoid inventing new components, and so forth and so on. Constraining generation shrinks the disturbance variety of the whole system by reducing what’s possible.

This vibes with my experience (pun intended).

Being an editor and “constraining generation” for the LLM seems like the primary function.
