Answers questions about a codebase from the knowledge graph built by the open-source Understand-Anything plugin, and covers installing the plugin and producing that graph. Use when someone asks "how does checkout work in this repo", "what calls this function", "where is rate limiting handled", "what depends on this module", "run /understand-chat", "set up Understand-Anything", or wants an architecture question answered with file paths and line numbers instead of guesses.
