I view any LLM generated code as a movie set, something that looks good, and has to last for one use. Use it like you would use Harbor Freight tools, as something to get a job done once, but not something to rely on.

LLMs can give you the API calls, and help you figure out how certain libraries work, but they're going to fail spectacularly on quality. I don't see any way around this for the next year or so.

The only positive suggestion I have is to keep the scope of your prompts tightly controlled. Be very, very specific in what you want, avoid wiggle room.
