What it does
Point it at 200,000 lines you have never seen and a multi-agent pipeline builds a knowledge graph of every file, function, class and dependency, then hands you a dashboard to explore and question it rather than reading blind. Installs as a plugin into Claude Code, Codex, Cursor, Copilot or Gemini CLI. The code being analysed goes to whichever model you have configured, which is the thing to check before pointing it at work repositories. Docs are available in Japanese among other languages. MIT.
