Build sophisticated multi-agent workflows with advanced orchestration patterns.

## 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/complex-workflows
cd complex-workflows
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
```

## Multi-Agent Workflow

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

// Create specialized agents
const researcher = await Agent.create({
  name: 'Researcher',
  model: 'gpt-4o',
  systemPrompt: 'You research topics thoroughly.'
});

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

// Create workflow pipeline
const pipeline = new Graph({
  name: 'content-pipeline'
}, researcher);

// Define workflow steps
const research = pipeline.addTaskNode({
  prompt: 'Research AI trends in 2024',
  agentId: researcher.id
});

const article = pipeline.addTaskNode({
  prompt: 'Write an article based on the research',
  agentId: writer.id,
  dependencies: [research]
});

// Execute the workflow
const results = await pipeline.run();

// Parse the result and extract the response
if (results.success && results.results[article]) {
  const articleResult = JSON.parse(results.results[article]);
  console.log(articleResult.response);
}
```

## Running the Example

If you cloned the repository:

```bash
npm run dev
```
