What it does
AI coding tools often reread large parts of a project to review a change. This tool builds a map of the code, showing which functions call which and which tests cover what, and keeps it up to date as files change.
When you ask an AI assistant to review a change, the map tells it exactly which files could be affected, so it reads less. Its makers publish measurements showing much smaller amounts of text sent to the AI.
It runs on your own computer and works with many AI coding tools, including Claude Code, Cursor, Codex and Gemini CLI.
