This hooks Claude up to Google's Gemini CLI for code review using Gemini 2.5 Pro's 1M token context window, which means you can feed it entire repositories without chunking. It scores 63.8% on SWE-Bench Verified and comes with a free tier of 1,000 requests per day. The setup involves installing the Node.js CLI and a code review extension, then either running it interactively or in headless mode for CI/CD. There's also a Gemini Code Assist GitHub app that auto-reviews PRs. The big win here is the massive context window combined with solid benchmark performance. If you're already using Claude but need a second opinion or want to leverage that huge context for repository-wide analysis, this gives you a quick way to pull in Gemini without switching your whole workflow.
