Understand

Generates an interactive knowledge graph of your codebase by analyzing files in batches and writing the results to `.understand-anything/knowledge-graph.json`. Works incrementally by default, only reprocessing what changed since the last run. The multilingual support is nice if you're documenting for non-English teams (pass `--language zh` or similar). It includes git worktree detection that redirects output to the main repo root, which matters if you're using Claude Code's ephemeral worktrees and don't want your graph deleted when the session ends. The progress reporting through seven phases keeps you sane on large repos. Most useful when onboarding to unfamiliar codebases or visualizing how components actually connect.
