Being doing toy-examples of non-trivial complexity. Architecting the code so context is obvious and there are clear breadcrumbs everywhere is the key. And the LLM can do most of this. Prototype-> refactor/cleanup -> more features -> refactor / cleanup add architectural notes.

If you know what a well architected piece of code is supposed to look like, and you proceed in steps, LLM gets quite far as long as you are handholding it. So this is usable for non-trivial _familiar_ code where typing it all would be slower than prompting the llm. Maintaining LLM context is the key here imo and stopping it when you see weird stuff. So it requires you act as thr senior partner PR:ing everyhting.
