Understand Domain

Extracts business domain knowledge from your codebase and renders it as an interactive horizontal flow graph showing domains, business flows, and process steps. It's smart about reuse: if you've already run /understand, it derives everything from that knowledge graph without rescanning files. Otherwise it does a lightweight scan of your file tree, entry points, and a few sample files. The worktree redirect logic is particularly thoughtful, it detects ephemeral Claude Code worktrees and writes output to your main repo so the graph doesn't vanish when the session ends. Pairs with the dashboard for visualization. Good for orienting yourself in unfamiliar codebases or mapping out what the system actually does at a business level.
