Install

/plugin install understand-anything

Our take

Uses a multi-agent pipeline to write a graph to .ua/knowledge-graph.json, then serves a web dashboard plus commands like /understand-chat, /understand-diff, and /understand-onboard. The README warns that the initial /understand run can consume a significant number of tokens on large projects; later runs are incremental. Beyond Claude Code, it supports Codex, Cursor, Copilot, Gemini CLI, and other tools through an install script, and it is MIT licensed and actively maintained.
