Outside of packages I doubt few of my code bases would fit into this. But the individual domain areas would. I don't care about users in a orders context, I don't care about payments when dealing with imports, no reason an ai should care either. It shouldn't care about implementations if there's an interface referenced, it shouldn't worry about front end when it's dealing with the back etc.

Scoping the Ai to only use the things you'd use seems far wiser than trying to reduce your codebase so it can look at the whole thing when 90% of it is irrelevant.
