3Launch your agent
Copy the ready-made code for this agent. It hides secrets and personal data before the AI model sees them.
Put each key in a password manager or your hosting's secret settings. Never paste keys or passwords into AItooling or a chat.
Start small, read every answer yourself, and only then let other people use it.
