It is remarkably effective to have Claude Code do the code review and assign a quality score, call it a grade, to the contribution derived from your own expectations of quality.

Then don’t even bother looking at C work or below.

IME it works even better if you use another model for review. We've seen code by cc and review by gpt5.2/3 work very well.

Also works with planning before any coding sessions. Gemini + Opus + GPT-xhigh works to get a lot of questions answered before coding starts.
