github-twin MCP

A personal RAG over your GitHub history and/or an organizations RAG over its GitHub history. It indexes commits and review comments, and surfaces them as retrieval hits whenever an agent writes or reviews new code in your style. Embeddings are computed locally, and it serves as a stdio server for MCP clients like Claude Code.
