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

const agent = await Agent.create({
  name: 'MemoryBot',
  model: 'gpt-4o',
  memory: true,
  systemPrompt: 'You remember our conversation history.'
});

// First conversation
const response1 = await agent.ask("My name is John and I like TypeScript");
console.log(response1);

// Later conversation - agent remembers
const response2 = await agent.ask("What's my name and what do I like?");
console.log(response2); // Should remember John and TypeScript
