I really think people are approaching LLMs wrong when it comes to code. Just directing an agent to make you something you’re unfamiliar with is always going to end up with this. It’s much better to have a few hours chat with the LLM and learn some about the topic, multiple times over many days, and then start.

And ask questions and read all the code and modify it yourself; and read the compile errors and try to fix then yourself; etc. Come back to the LLM when you’re stuck.

Having the machine just build you something from a two sentence prompt is lazy and you’ll feel lazy and bad.

Learn with it and improve with it. You’ll end up with more knowledge and a code base for a project that you do (at least somewhat) understand, and you’ll have a project that you wouldn’t have attempted otherwise.
