A fun trick I’ve used lately is to have Claude Code and Gemini critique each other through a Markdown document conversation. It’s surprisingly effective.

In Claude Code, I’ll have it do some work without checking it in just yet. Then I’ll start up gemini in the same working directory and say:

You’re a code reviewer. You will not edit code. Review the current changes. They were intended to [bug/feature description]. Evaluate the solution and write your review to reviews/Review-1.md and I will inform the other coder.
