Understand

Turns your codebase into an interactive knowledge graph that maps out architecture, components, and relationships. It crawls your files, analyzes them in batches, and spits out a JSON graph you can explore through a dashboard. The incremental mode is smart enough to only reprocess what changed since your last commit, which matters when you're working on a large repo. There's a worktree redirect that saves the graph to your main repo instead of ephemeral checkouts, plus multi-language support for summaries and descriptions. The progress reporting during long analyses is a nice touch. If you've ever inherited a sprawling codebase and wished for a map, this is that map.
