diffray Free open-source multi-agent code review

**What is this?** A CLI tool that runs multiple AI agents to review your code changes. Each agent specializes in different aspects: bugs, security, performance, code style. Works with [Claude Code](https://github.com/anthropics/claude-code), [Cursor Agent](https://cursor.com), OpenCode, or Codex CLI.

**How is it different from [diffray.ai](https://diffray.ai)?** The cloud platform automatically learns from your team's review feedback and generates rules. This CLI version requires manual rule configuration but gives you full control and runs locally.
