Rubi

Rubi is a knowledge graph and context management tool designed for AI coding agents like Claude Code, Codex, Gemini CLI, Cursor, Copilot, and local models. It builds a code map with PageRank, a temporal knowledge graph of decisions and bugs, and integrates hybrid search to reduce context re-reading costs, shorten sessions, and improve project navigation. It operates locally with markdown files and supports multiple AI agents via a standard MCP server interface.
