What is Human in the loop?
Also called: Human approval
Human in the loop means a person checks and approves before the AI does something important, such as sending an email or paying money.
Example
The agent drafts the reply to the customer; you click “Send”.
For pros
Put approval points before every action that reaches outside, costs money or cannot be undone. This reduces risk from errors, hallucinations and prompt injection.
