# CopilotKit Quick Reference

## Need to...?

### Build a Simple Copilot
- Start with [copilot-chat-with-your-data/](mdc:examples/copilot-chat-with-your-data)
- Use [react-core/](mdc:packages/react-core) for basic integration
- Add [react-ui/](mdc:packages/react-ui) for pre-built components

### Create Multi-Agent Systems
- Check [coagents-starter/](mdc:examples/coagents-starter) for basic setup
- Use [coagents-routing/](mdc:examples/coagents-routing) for routing patterns
- See [coagents-shared-state/](mdc:examples/coagents-shared-state) for state management

### Integrate with CrewAI
- **Flows**: [coagents-starter-crewai-flows/](mdc:examples/coagents-starter-crewai-flows)

### Develop Python Agents
- Use [sdk-python/](mdc:sdk-python) package
- Check [copilotkit/agent.py](mdc:sdk-python/copilotkit/agent.py) for main agent class
- See [coagents-starter/agent-py/](mdc:examples/coagents-starter/agent-py) for example

### Develop JavaScript Agents
- Use [sdk-js/](mdc:packages/sdk-js) package
- Check [coagents-starter/agent-js/](mdc:examples/coagents-starter/agent-js) for example

### Customize UI Components
- Browse [registry/](mdc:registry) for reusable components
- Check [docs/components/react/](mdc:docs/components/react) for documentation
- Use [react-ui/](mdc:packages/react-ui) for pre-built components

### Set Up Development Environment
- Review [package.json](mdc:package.json) for workspace setup
- Use scripts in [scripts/](mdc:scripts)
- Check [utilities/](mdc:utilities) for shared configurations

### Run Tests
- Use [examples/e2e/](mdc:examples/e2e) for end-to-end testing
- Check [playwright.config.ts](mdc:examples/e2e/playwright.config.ts) for configuration

### Build Documentation
- Check [docs/](mdc:docs) for documentation site
- Use [docs/snippets/](mdc:docs/snippets) for code examples
- See [docs/content/docs/](mdc:docs/content/docs) for markdown files

## Key Files to Know
- **[package.json](mdc:package.json)** - Main workspace configuration
- **[sdk-python/pyproject.toml](mdc:sdk-python/pyproject.toml)** - Python SDK configuration
- **[CopilotKit.code-workspace](mdc:CopilotKit.code-workspace)** - VS Code workspace settings
- **[examples/shared/](mdc:examples/shared)** - Shared utilities and templates

## Common Patterns
1. **Frontend**: Next.js app with CopilotProvider and CopilotChat
2. **Backend**: Python or Node.js agent with actions and state management
3. **Integration**: Runtime connects frontend to backend agents
4. **Testing**: Playwright E2E tests for full integration validation

## Getting Started Checklist
1. Clone the repository
2. Navigate to the project root directory
3. Run `npm install` to set up workspace
4. Choose an example from [examples/](mdc:examples)
5. Follow the example's README.md
6. Start developing your custom copilot or agent
