Human-in-the-Loop
also HITL
A design pattern where a person reviews, approves, or corrects an AI system's output or actions at key points before they take effect.
Analogy
Like a draft that needs a manager's sign-off before it goes out.
Why it matters
It is the safety valve for letting Claude or an agent act on client accounts while you stay in control of risky steps.
In practice
An agent drafting an invoice but waiting for your approval click before it actually sends.
