Gemini Peer Review

Gemini Peer Review

A Claude Code plugin that validates Claude's designs, code reviews, and recommendations using Google Gemini CLI as a second AI perspective.

Why Peer Review?

Two AI perspectives catch more issues than one. Before presenting implementation plans, architecture recommendations, or code review findings, this plugin validates Claude's work through Gemini CLI to:

• Catch blind spots in analysis
• Identify alternative approaches
• Surface potential issues early
• Increase confidence in recommendations

Requirements

• Claude Code CLI
• Google Gemini CLI (v0.24.5 or later)

# macOS (Homebrew)
brew install gemini-cli

# Or via npm
