I would be curious to see how one could use LLMs to develop "narrow" parts of the codebase in isolation. I.e. I ask smol to develop a repository/web router/ etc. given an interface within a folder/package. Then I as the human developer focus on designing these interfaces.

Maybe that is a good balance for maintaining a healthy code structure while having a lot of AI automation. If a given "space" becomes too difiicult for the AI to develop, I can either take it over fully or see if I can split it up into more/different interfaces (which is a lot of what I do to refactor things anyway).
