Something funny happens when you reject code. The agent realises it is garbage.

I'm personally of the opinion that the tools for reviewing LLM generated code are awful. 99% of the time I want to do line by line comments and tell it everything it did wrong. Given that information, the next iteration would be much more up to my standards.

The same also applies to other people's LLM generated code. Yeah sure they can just pass on the comments to the LLM, but that will just mean more iterations and them losing their job.
