Question:

Should I ask it to update an existing project largely written in 3.7 or ask it to start from scratch?

I keep running into an issue where an LLM will get like 75% of a solution working and then the last 25% is somehow impossible to get right.

I don’t expect perfection, but I’ve wasted so much time vibe coding this thing I guess I’d do better to actually program

Update the old code, but make sure you’re using short (<350 line) files, and improve the type safety and code structure if possible.

You have to guide these models. Vibe coding does not work.
