According to all the magazines I've been reading, all that is required is to just prompt it with "please fix all of these issues" and give it a bulleted list with a single sentence describing each issue. I mean, it's AI powered and therefore much better than overpaid prima-donna engineers, so obviously it should "just work" and all the problems will get fixed. I'm sure most of the bugs were the result of humans meddling in the AI's brilliant output.
Right now, in fact, my understanding is OpenAI is using their current LLM's to write the next generation ones which will far surpass anything a developer can currently do. Obviously we'll need to keep management around to tell these things what to do, but the days of being a paid software engineer are numbered.
