I think maybe there's another step too - breaking the design up into small enough peices that the LLM can follow it, and you can understand the output.

So do all the hard work yourself and let the AI do some of the typing, that you’ll have to spend extra time reviewing closely in case its RNG factor made it change an important detail. And with all the extra up front design, planning, instructions, and context you need to provide to the LLM I’m not sure I’m saving on typing. A lot of people recommend going meta and having LLMs generate a good prompt and sequence of steps to follow, but I’ve only seen that kinda sorta work for the most trivial tasks.
