Understand Domain

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

Dev & CodingIntermediate★ 91,543⑂ 7,812AI score 7/10Last updated: Nov 7, 2026

What it does

  • Analyzes a codebase to extract domains, business flows, and process steps.
  • If a /understand knowledge graph already exists (.ua/knowledge-graph.json), derives the domain model from it — cheap, no file scanning.
  • Otherwise runs a lightweight scan (file tree, entry-point detection, sampled files) via a bundled Python preprocessor and hands the result to a domain-analyzer subagent.
  • Validates the output, saves domain-graph.json, and auto-launches the dashboard with the horizontal domain flow view.
  • Detects git worktrees and redirects output to the main repo root so the graph isn't destroyed when the session ends.

Who it's for

  • Developers ramping up on an unfamiliar codebase who need a business-level map.
  • Tech leads producing onboarding material for new hires.
  • Engineers untangling a legacy monolith and defining domain boundaries.

Examples

  1. Run /understand first, then /understand-domain to generate flow graphs for checkout, orders, and notifications.
  2. Run /understand-domain with no prior graph to get an entry-point-driven map from HTTP routes, CLI commands, and cron jobs.
  3. After a large refactor, run /understand-domain --full to ignore the cached graph and rescan from scratch.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/Egonex-AI/Understand-Anything/HEAD/understand-anything-plugin/skills/understand-domain/SKILL.md

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 AI 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 && mkdir -p ~/.claude/skills && 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 repository: git clone https://github.com/Egonex-AI/Understand-Anything.git ~/understand-anything
  2. Enter the plugin directory: cd ~/understand-anything/understand-anything-plugin
  3. Install dependencies (pnpm required): pnpm install
  4. Copy or symlink the skills into Claude's skill folder: mkdir -p ~/.claude/skills && cp -r skills/* ~/.claude/skills/
  5. Verify that agents/ and extract-domain-context.py are present. If the skill can't locate the plugin root, set CLAUDE_PLUGIN_ROOT to the plugin directory.
  6. Restart Claude Code, cd into the project you want to analyze, and run /understand-domain (add --full to force a fresh scan).
