**You just joined a new team. The codebase is 200,000 lines of code. Where do you even start?**

Understand Anything is a [Claude Code Plugin](https://code.claude.com/docs/en/plugins-reference#plugins-reference) that analyzes your project with a multi-agent pipeline, builds a knowledge graph of every file, function, class, and dependency, then gives you an interactive dashboard to explore it all visually. Stop reading code blind. Start seeing the big picture.

> **The goal isn't a graph that wows you with how complex your codebase is — it's a graph that quietly teaches you how every piece fits together.**

---

## ✨ Features

> [!NOTE]
> **Want to skip the reading?** Try the [live demo](https://understand-anything.com/demo/) in our [homepage](https://understand-anything.com/) — a fully interactive dashboard you can pan, zoom, search, and explore right in your browser.

### Explore the structural graph

Navigate your codebase as an interactive knowledge graph — every file, function, and class is a node you can click, search, and explore. Select any node to see plain-English summaries, relationships, and guided tours.

### Understand business logic

Switch to the domain view and see how your code maps to real business processes — domains, flows, and steps laid out as a horizontal graph.

### Analyze knowledge bases

Point `/understand-knowledge` at a [Karpathy-pattern LLM wiki](https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f) and get a force-directed knowledge graph with community clustering. The deterministic parser extracts wikilinks and categories from `index.md`, then LLM agents discover implicit relationships, extract entities, and surface claims — turning your wiki into a navigable graph of interconnected ideas.

## 🚀 Quick Start

### 1. Install the plugin

```bash
/plugin marketplace add Egonex-AI/Understand-Anything
/plugin install understand-anything
```

> **Using a local model?** For privacy or enterprise setups, point your platform at a local model provider such as [Ollama](https://docs.ollama.com/integrations) — follow their integration guide to change the model provider.

### 2. Analyze your codebase

```bash
/understand
```

A multi-agent pipeline scans your project, extracts every file, function, class, and dependency, then builds a knowledge graph saved to `.ua/knowledge-graph.json`. (Projects that already have a `.understand-anything/` directory keep using it — it stays the data directory when present, so nothing needs migrating.)

> **Heads up on token usage:** The initial `/understand` analyzes your whole codebase and can consume a significant number of tokens on large projects. We recommend running it on a token plan / subscription, or using a local model (see above) for initialization. Subsequent runs are incremental by default — only changed files are re-analyzed — so they use far fewer tokens.

**Localized output:** Use `--language` to generate content in your preferred language:

```bash
# Generate Chinese content (知识图节点描述和 Dashboard UI)
/understand --language zh

# Supported languages: en (default), zh, zh-TW, ja, ko, ru, vi
```

On the **first run** in a project — when you don't pass `--language` and no language is stored yet — `/understand` detects the language you're conversing in. If it isn't English, it asks you to confirm (or override) before generating; English conversations are unaffected. Your choice is saved to `.ua/config.json` and reused on every later run.

The `--language` parameter affects:
- Node summaries and descriptions in the knowledge graph
- Dashboard UI labels, buttons, and tooltips
- Guided tour explanations

### 3. Explore the dashboard

```bash
/understand-dashboard
```

An interactive web dashboard opens with your codebase visualized as a graph — color-coded by architectural layer, searchable, and clickable. Select any node to see its code, relationships, and a plain-English explanation.

### 4. Keep learning

```bash
# Ask anything about the codebase
/understand-chat How does the payment flow work?

# Analyze impact of your current changes
/understand-diff

# Deep-dive into a specific file or function
/understand-explain src/auth/login.ts

# Generate an onboarding guide for new team members
/understand-onboard

# Extract business domain knowledge (domains, flows, steps)
/understand-domain

# Analyze a Karpathy-pattern LLM wiki knowledge base
/understand-knowledge ~/path/to/wiki

# Re-run anytime — incremental by default (only re-analyzes changed files)
/understand

# Auto-update on every commit via a post-commit hook
/understand --auto-update

# Scope to a subdirectory (for huge monorepos)
/understand src/frontend
```

## 🌐 Multi-Platform Installation

Understand-Anything works across multiple AI coding platforms.

### Claude Code (Native)

```bash
/plugin marketplace add Egonex-AI/Understand-Anything
/plugin install understand-anything
```


### One-line install (Codex / OpenCode / OpenClaw / Antigravity / Gemini CLI / Pi Agent / Vibe CLI / VS Code Copilot / Hermes / Cline / KIMI CLI / Trae / Nanobot / Kiro)


**macOS / Linux:**
```bash
curl -fsSL https://raw.githubusercontent.com/Egonex-AI/Understand-Anything/main/install.sh | bash
# or skip the prompt by passing the platform:
curl -fsSL https://raw.githubusercontent.com/Egonex-AI/Understand-Anything/main/install.sh | bash -s codex
```

**Windows (PowerShell):**
```powershell
iwr -useb https://raw.githubusercontent.com/Egonex-AI/Understand-Anything/main/install.ps1 | iex
```

The installer clones the repo to `~/.understand-anything/repo` and creates the right symlinks for the chosen platform. Restart your CLI/IDE afterwards.

> **Note on invoking skills:** the invocation prefix differs per platform. Most platforms use slash commands (`/understand`), but **Codex uses `$` instead** — type `$understand`, not `/understand`. If neither prefix is recognized on your platform, just ask in plain language: *"Use the understand skill to analyze this project."*

- Supported `<platform>` values: `gemini`, `codex`, `opencode`, `pi`, `openclaw`, `antigravity`, `vibe`, `vscode`, `hermes`, `cline`, `kimi`, `trae`, `nanobot`, `kiro`
- Update later:
  - macOS / Linux: `./install.sh --update`
  - Windows: `& "$HOME/.understand-anything/repo/install.ps1" -Update`
- Uninstall:
  - macOS / Linux: `./install.sh --uninstall <platform>`
  - Windows: `& "$HOME/.understand-anything/repo/install.ps1" -Uninstall <platform>`

### Cursor

Cursor auto-discovers the plugin via `.cursor-plugin/plugin.json` when this repo is cloned. No manual installation needed — just clone and open in Cursor.

If auto-discovery doesn't pick it up, install it manually: open **Cursor Settings → Plugins**, paste `https://github.com/Egonex-AI/Understand-Anything` into the search field, and add it from there.

### VS Code + GitHub Copilot

VS Code with GitHub Copilot (v1.108+) auto-discovers the plugin via `.copilot-plugin/plugin.json` when this repo is cloned. No manual installation needed — just clone and open in VS Code.

For personal skills (available across all projects), run the `install.sh` above with the `vscode` platform.

### Copilot CLI

```bash
copilot plugin install Egonex-AI/Understand-Anything:understand-anything-plugin
```

### Kiro CLI / IDE

```bash
curl -fsSL https://raw.githubusercontent.com/Egonex-AI/Understand-Anything/main/install.sh | bash -s kiro
```

After installation:
- **Kiro CLI**: `kiro-cli chat --agent understand "Analyze this project"`
- **Kiro IDE**: The skills are symlinked into `~/.kiro/skills/` and the `understand` agent is written to `~/.kiro/agents/understand.json`, so both are available after restarting the IDE.

For personal skills (available across all projects), run the `install.sh` above with the `kiro` platform.

## 📦 Share the Graph with Your Team

The graph is just JSON — **commit it once, and teammates skip the pipeline**. Good for onboarding, PR reviews, and docs-as-code.

> **Example:** [GoogleCloudPlatform/microservices-demo](https://github.com/GoogleCloudPlatform/microservices-demo) — Go / Java / Python / Node reference with a committed graph.

**What to commit:** everything in `.ua/` *except* `intermediate/` and `diff-overlay.json` (those are local scratch). (Legacy projects use `.understand-anything/` — substitute that directory name below if it's the one present.)

```gitignore
.ua/intermediate/
.ua/diff-overlay.json
```

**Keep it fresh:** enable `/understand --auto-update` — a post-commit hook incrementally patches the graph so each commit lands with a matching graph. Or re-run `/understand` manually before releases.

**Large graphs (10 MB+):** track with **git-lfs**.

```bash
git lfs install
git lfs track ".ua/*.json"
git add .gitattributes .ua/
```

### View the dashboard without Claude Code

Once a graph has been generated and committed, anyone on the team can open it with one command — no Claude Code, no LLM, no API key. Only Node.js (>= 18) is required:

```bash
npx https://github.com/Egonex-AI/Understand-Anything/releases/latest/download/understand-anything-viewer.tgz /path/to/analyzed/project
```

The terminal prints a tokenized URL (`http://127.0.0.1:5173/?token=…`) and opens the full interactive dashboard in your browser. The project directory (default: current directory) must contain the committed data directory (`.ua/`, or legacy `.understand-anything/`). Everything is served read-only from local disk — no LLM calls, no data leaves your machine.

Working from a clone instead? `pnpm install && pnpm --filter @understand-anything/core build`, then `GRAPH_DIR=/path/to/analyzed/project pnpm dev:dashboard` does the same via the Vite dev server.

## 🔧 Under the Hood

### Tree-sitter + LLM hybrid

Static analysis and LLMs do what each does best:

- **Tree-sitter (deterministic)** — parses source into a concrete syntax tree and extracts structural facts: imports, exports, function/class definitions, call sites, inheritance. Pre-resolved into an `importMap` during the scan phase and passed to file-analyzers so they don't re-derive imports from source. Same input → same output, every run. Also powers fingerprint-based change detection for incremental updates.
- **LLM (semantic)** — reads the parsed structure alongside the original source to produce what parsers can't: plain-English summaries, tags, architectural layer assignments, business-domain mapping, guided tours, language concept callouts.

This split is why the graph is reproducible on the structural side (the same code always yields the same edges) while still capturing intent on the semantic side (what a file is *for*, not just what it imports).

### Multi-Agent Pipeline

The `/understand` command orchestrates 5 specialized agents, `/understand-domain` adds a 6th, and `/understand-knowledge` adds a 7th:

| Agent                   | Role                                                                                                               | Used By                 |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------ | ----------------------- |
| `project-scanner`       | Discovers files, detects languages and frameworks                                                                  | `/understand`           |
| `file-analyzer`         | Extracts functions, classes, imports; produces graph nodes and edges                                               | `/understand`           |
| `architecture-analyzer` | Identifies architectural layers                                                                                    | `/understand`           |
| `tour-builder`          | Generates guided learning tours                                                                                    | `/understand`           |
| `graph-reviewer`        | Validates graph completeness and referential integrity. Runs inline by default; use `--review` for full LLM review | `/understand`           |
| `domain-analyzer`       | Extracts business domains, flows, and process steps                                                                | `/understand-domain`    |
| `article-analyzer`      | Extracts entities, claims, and implicit relationships from wiki articles                                           | `/understand-knowledge` |

File analyzers run in parallel, up to 5 concurrent workers and 20–30 files per batch.

The pipeline also supports incremental updates: only files changed since the last run are re-analyzed.
