Understand: Codebase Knowledge Graph

Scans a repository and builds an interactive knowledge graph of its architecture, components, and relationships.

Dev & CodingIntermediate★ 81,394⑂ 6,843AI score 9/10Last updated: Sep 3, 2026

What it does

  • Scans the project to detect languages, frameworks, file inventory and complexity, then emits file-level nodes and relationship edges (imports, configures, tested_by, etc.) into .ua/knowledge-graph.json.
  • Runs a disciplined 7-phase pipeline (pre-flight → scan → semantic batching → parallel analysis → merge review → architecture layers → cleanup) with progress reporting at every phase.
  • Supports incremental updates driven by git commit diffs, scope control via .understandignore and --exclude, and localized output via --language <code>.
  • Merges subdomain graphs (e.g. frontend/backend) into one graph that powers an interactive exploration dashboard.

Who it's for

  • Developers inheriting a large or legacy repository who need a fast structural map.
  • Team leads generating onboarding and architecture documentation automatically.
  • Architects auditing layer boundaries and module dependencies inside a monorepo.

Examples

  • /understand — analyze the current directory and build the initial graph.
  • /understand --full --language en --exclude "tests/*,docs/*" — full rebuild while skipping tests and docs.
  • /understand ../other-project --auto-update — analyze another repo and keep its graph refreshed on each commit.

  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 folder from the GitHub repo Egonex-AI/Understand-Anything into my ~/.claude/skills/understand/.
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/understand ~/.claude/skills/understand

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

  1. Install Node.js 22+ and pnpm 10+ (verify with node -v and pnpm -v); Python 3 is also needed for the merge scripts.
  2. Clone the repository: git clone https://github.com/Egonex-AI/Understand-Anything.git ~/understand-anything
  3. Build the plugin core: cd ~/understand-anything/understand-anything-plugin && pnpm install && pnpm --filter @understand-anything/core build
  4. Copy the skill into Claude Code: mkdir -p ~/.claude/skills && cp -r ~/understand-anything/understand-anything-plugin/skills/understand ~/.claude/skills/understand (confirm the bundled agents/, languages/, frameworks/ folders and *.mjs / *.py scripts came along).
  5. Open Claude Code inside the project you want to analyze and run /understand.
  6. On the first run, review the generated .ua/.understandignore, adjust exclusion patterns, then confirm to start the analysis.
