One little detail. The models are already pre trained on similar system implementations. Likely whatever you are building has been built in some form or shape in the past and the ambiguity is resolved by someone in the training set.

In my experience “we need so create something for this regulatory change / new industry trend” is more common than we need to redo a working piece of software that’s been done before.

That “likely” is doing a lot of work, especially in mission critical software.
