Quick Start

// 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%
