Instance Config (instance.yaml)

id: "abc12345"
name: "Research Assistant"
role: standalone
port: 3002

Assistant: [REMEMBER]User prefers TypeScript over JavaScript[/REMEMBER]
I'll remember that you prefer TypeScript!

Integration

const response = await fetch('http://localhost:3001/chat', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ message: 'Hello!' })
});
const data = await response.json();
console.log(data.content);
