Understand Domain

Extracts business domains, flows, and process steps from a codebase and renders them as an interactive flow graph.

Dev & CodingIntermediate★ 83,859⑂ 7,068AI score 8/10Last updated: Sep 12, 2026

What it does

  • Analyzes your repository to surface business domains → business flows → process steps.
  • Reuses an existing knowledge graph (.ua/knowledge-graph.json from /understand) to derive domain knowledge cheaply, with a staleness preflight against git diffs.
  • Falls back to a lightweight Python preprocessing scan (file tree, entry points such as HTTP routes/CLI commands/event handlers/cron jobs, export-import signatures) when no graph exists.
  • Saves the result to domain-graph.json and auto-launches /understand-dashboard for a horizontal flow visualization.
  • Detects git worktrees and redirects output to the main repo root so generated graphs survive the session.

Who it's for

  • Developers onboarding into a large or legacy codebase who need the business logic map fast.
  • Tech leads and architects documenting how code maps to real business processes.
  • Teams that want auto-generated domain/onboarding documentation.

Examples

  1. /understand-domain — derive flows from the existing knowledge graph and open the dashboard.
  2. /understand-domain --full — force a fresh scan after a large refactor.
  3. Run it in a repo with no prior graph — the preprocessing script finds entry points and the analyzer groups them into domains like billing, accounts, and notifications.

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the understand-anything-plugin/skills/understand-domain folder from the GitHub repo Egonex-AI/Understand-Anything into my ~/.claude/skills/understand-domain/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/Egonex-AI/Understand-Anything.git ~/understand-anything && cp -r ~/understand-anything/understand-anything-plugin/skills/* ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Clone the plugin repository: git clone https://github.com/Egonex-AI/Understand-Anything.git ~/understand-anything
  2. Install plugin dependencies (it's a pnpm monorepo): cd ~/understand-anything/understand-anything-plugin && pnpm install
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the skills over: cp -r ~/understand-anything/understand-anything-plugin/skills/* ~/.claude/skills/
  5. Verify Python is available with python3 --version (needed by the preprocessing script).
  6. Open Claude Code in the project you want to analyze and run /understand-domain.
  7. If you see "Cannot find the understand-anything plugin root", move or symlink the plugin into one of the listed paths (e.g. ~/understand-anything/understand-anything-plugin).
