Are you hand-fixing the issues or having AI do it? I've found that second pass quality is miles away from an initial implementation. If you're experienced, you'll know exactly where the code smells are. Point this out, and the agents will produce a much better implementation in this second pass. And have those people store the promps in the repo! I put my specifications in ./doc/spec/*.md

Every time I got bad results, looking back I noticed my spec was just vague or relied on assumptions. Of course you can't fix your collegues, if they suck they suck and sombody gotta do the mopping :)
