Create and coordinate multiple AI agents for complex task delegation.

## Quick Start

### Clone the Complete Example

The easiest way to get started is to clone the complete example repository:

```bash
git clone https://github.com/astreus-ai/sub-agents-basic
cd sub-agents-basic
npm install
```

### Or Install Package Only

If you prefer to build from scratch:

```bash
npm install @astreus-ai/astreus
```

## Environment Setup

```bash
# .env
OPENAI_API_KEY=sk-your-openai-api-key-here
DB_URL=sqlite://./astreus.db
```

## Simple Sub-Agent Setup

```typescript
import { Agent } from '@astreus-ai/astreus';

// Create specialized sub-agents
const researcher = await Agent.create({
  name: 'Researcher',
  model: 'gpt-4o',
  systemPrompt: 'You are an expert researcher who gathers comprehensive information.'
});

const writer = await Agent.create({
  name: 'Writer',
  model: 'gpt-4o',
  systemPrompt: 'You are a skilled writer who creates clear, engaging content.'
});

// Create main coordinator agent
const mainAgent = await Agent.create({
  name: 'Coordinator',
  model: 'gpt-4o',
  systemPrompt: 'You coordinate tasks between specialized agents.',
  subAgents: [researcher, writer]
});

// Use auto delegation
const result = await mainAgent.ask(
  'Research artificial intelligence trends and write a summary',
  {
    useSubAgents: true,
    delegation: 'auto'
  }
);

console.log(result);
```

## Running the Example

If you cloned the repository:

```bash
npm run dev
```

If you built from scratch, create an `index.ts` file with the code above and run:

```bash
