**You can contribute to Understand Anything by forking the repository, setting up the pnpm monorepo with Node ≥ 22, and submitting pull requests that follow conventional commit conventions and include Vitest coverage.**

Understand Anything is a **multi-agent, tree-sitter-plus-LLM** code-analysis platform that transforms massive codebases into interactive knowledge graphs. Contributing to the Egonex-AI Understand Anything project involves working within a structured pnpm monorepo that separates static analysis logic from the React 18 dashboard interface.

## Prerequisites and Environment Setup

The project requires **Node.js ≥ 22** and **pnpm ≥ 10** to manage the monorepo dependencies. All contribution workflows begin with the standard fork-branch-PR model documented in [`CONTRIBUTING.md`](https://github.com/Egonex-AI/Understand-Anything/blob/main/CONTRIBUTING.md).

### Fork and Clone the Repository

Start by forking the repository on GitHub, then clone your fork locally:

```bash
git clone https://github.com/YOUR_USERNAME/Understand-Anything.git
cd Understand-Anything

```

### Install Dependencies

Install all monorepo dependencies using pnpm:

```bash
pnpm install

```

### Build the Core Package

Before running tests or making changes, build the core package to generate TypeScript types:

```bash
pnpm --filter @understand-anything/core build

```

### Verify Your Setup

Run the full test suite to ensure your environment is correctly configured:

```bash
pnpm --filter @understand-anything/core test
pnpm --filter @understand-anything/skill test
pnpm test   # Runs all packages

```

## Where to Contribute

The monorepo organizes code into two primary packages under `understand-anything-plugin/packages`: **`@understand-anything/core`** (static analysis engine) and **`@understand-anything/dashboard`** (React 18 UI). Choose your contribution area based on your expertise.

### Core Engine (`@understand-anything/core`)

Work on the static analysis engine located in `understand-anything-plugin/packages/core/src/**` to improve tree-sitter parsing accuracy, add new language extractors, or optimize incremental change detection algorithms.

### Dashboard UI (`@understand-anything/dashboard`)

Contribute to the React 18 interface in `understand-anything-plugin/packages/dashboard/src/**` to add keyboard shortcuts, refine graph layouts using React Flow, update TailwindCSS v4 theme colors, or improve accessibility. The graph layout logic resides in [`packages/dashboard/src/components/Graph.tsx`](https://github.com/Egonex-AI/Understand-Anything/blob/main/packages/dashboard/src/components/Graph.tsx), which uses Zustand for state management.

### Skill Definitions

Create new `/understand-*` skills or extend language support by modifying files in `understand-anything-plugin/skills/**`. Skills define how the AI agents interact with specific codebases and technologies.

### AI Agents

Refine prompt templates for the multi-agent pipeline in `understand-anything-plugin/agents/**`. Key agents include `project-scanner`, `file-analyzer`, and `architecture-analyzer`, each defined in separate markdown files containing role-specific prompt templates.

### Documentation and Translations

Update [`README.md`](https://github.com/Egonex-AI/Understand-Anything/blob/main/README.md), [`CONTRIBUTING.md`](https://github.com/Egonex-AI/Understand-Anything/blob/main/CONTRIBUTING.md), or add translation files in `understand-anything-plugin/skills/understand/locales/*.md` and `READMEs/README.*.md` to support new languages.

### Test Coverage

Write Vitest test cases for new functionality in `**/*.test.ts` files under each package, such as `understand-anything-plugin/packages/core/**/*.test.ts`.

## Development Workflow

Follow the standardized workflow to ensure your changes integrate smoothly into the multi-agent codebase analysis pipeline.

### Create a Feature Branch

Always work on a dedicated branch rather than `main`:

```bash
git checkout -b feat/add-dark-mode

```

### Implement and Test

Make your changes in the appropriate package directory. For example, adding a dark-mode toggle to the dashboard requires editing files under `packages/dashboard/src/components/`.

Add corresponding unit tests:

```bash

# Create test file following existing patterns

# packages/dashboard/src/components/DarkModeToggle.test.ts

```

Run the full test suite before committing:

```bash
pnpm test

```

### Commit with Conventional Messages

Use conventional commit prefixes (`feat:`, `fix:`, `docs:`, `test:`) as specified in [`CONTRIBUTING.md`](https://github.com/Egonex-AI/Understand-Anything/blob/main/CONTRIBUTING.md):

```bash
git add .
git commit -m "feat: add dark-mode toggle to dashboard"

```

### Submit Your Pull Request

Push your branch and open a Pull Request on GitHub:

```bash
git push origin feat/add-dark-mode

```

Link any related issues in your PR description and ensure all checklist items are satisfied.

## Pull Request Requirements

Every contribution must meet the quality standards defined in the [`CONTRIBUTING.md`](https://github.com/Egonex-AI/Understand-Anything/blob/main/CONTRIBUTING.md) PR checklist:

- **Code style**: Follow ESLint/Prettier rules with **2-space indentation** and strict TypeScript configuration.
- **Test coverage**: All new code must include Vitest unit tests.
- **CI passing**: `pnpm test` must pass for the entire monorepo.
- **Documentation**: Update README, skill documentation, or translation files to reflect changes.
- **Commit hygiene**: Use conventional commit prefixes and remove stray `console.log` statements.

## Summary

- **Understand Anything** is a pnpm monorepo requiring Node ≥ 22 and pnpm ≥ 10.
- **Core contributions** target `understand-anything-plugin/packages/core/src/**` for tree-sitter parsing improvements.
- **UI contributions** target `understand-anything-plugin/packages/dashboard/src/**` using React Flow and Zustand.
- **Agent contributions** involve refining prompts in `understand-anything-plugin/agents/**`.
- **Always run** `pnpm --filter @understand-anything/core build` before testing and `pnpm test` before submitting.
- **Follow conventional commits** (`feat:`, `fix:`, `docs:`) and maintain strict TypeScript with 2-space indentation.

## Frequently Asked Questions

### What are the system requirements for contributing to Understand Anything?

You need **Node.js version 22 or higher** and **pnpm version 10 or higher** installed on your system. The project uses pnpm workspaces to manage the monorepo structure, and attempting to use npm or yarn will result in dependency resolution errors.

### How do I run tests for only the core package?

Use the pnpm filter flag to target specific packages: `pnpm --filter @understand-anything/core test` runs only the core engine tests, while `pnpm --filter @understand-anything/skill test` runs skill-specific tests. Run `pnpm test` from the root to execute the full suite across all packages.

### Where should I start if I want to add support for a new programming language?

Add new language extractors to the core engine in `understand-anything-plugin/packages/core/src/**` and create corresponding skill definitions in `understand-anything-plugin/skills/**`. You will also need to update the tree-sitter parsing logic to handle the new language's grammar and import mapping.

### What makes a contribution likely to be accepted quickly?

Contributions that include **comprehensive Vitest test coverage**, follow the **2-space indentation** and ESLint rules, use **conventional commit messages**, and update relevant documentation in [`README.md`](https://github.com/Egonex-AI/Understand-Anything/blob/main/README.md) or `understand-anything-plugin/skills/understand/locales/` align with the project's standards and typically move through review faster.
