The agent is instructed to use Laws of UX[0] when reviewing application flows and cite specific laws with changes to the builder agents. Look-and-feel in general still requires some tuning, but I have found that: 1) using a discrete agent in this role that only looks at the flow and is given the end-user context, 2) pointed to a set of guidance has really improved autonomy for UX.
It certainly is less important as the models get better at meta planning, but this approach is still very useful.
Often all you need to do is define a set of beliefs and values for the role and it will operate much better than rules or guidance.
