### 1. Install

```bash
npm install agent-guard
```

---

### Quick Start
```javascript
// Step 1: Add these two lines to your AI agent
const agentGuard = require('agent-guard');
await agentGuard.init({ limit: 25 });  // $25 budget limit

// Step 2: Your existing code works unchanged
const response = await openai.chat.completions.create({
  model: 'gpt-4',
  messages: [{ role: 'user', content: 'Hello world' }]
});
console.log('Response:', response); // ← AgentGuard automatically tracks this

// Real-time protection: 🛡️ $12.34 / $25.00 49.4%
```

---

### Production Deployment
```javascript
// Multi-process protection with Redis
await agentGuard.init({
  limit: 1000,
  mode: 'throw',
  redis: 'redis://production:6379',
  webhook: 'https://hooks.slack.com/alerts'
});
```

### Accurate Cost Calculation
- **Real tokenizers**: OpenAI's `tiktoken` + Anthropic's official tokenizer
- **Live pricing**: Fetches current rates from community sources
- **Streaming support**: Accumulates tokens from partial responses
- **Multimodal**: Handles images, audio, and complex content
- **Smart fallback**: Accurate estimation when tokenizers unavailable
