Human-in-the-Loop for Agents

Human-in-the-loop for agents is a design pattern that pauses an autonomous workflow at defined checkpoints so a person can approve, edit, or reject the next action.

It covers approval gates, escalation policies, and feedback loops that let teams hand routine work to agents while keeping a human accountable for sensitive decisions like payments, code merges, or customer messages. Also known as: HITL.

What this topic covers

Foundations — Human-in-the-loop is less about slowing agents down and more about choosing which decisions belong to a person.
Implementation — Adding HITL to an agent means picking the right interrupt mechanism, designing the approval UI, and handling resume state cleanly.
What's changing — Frameworks are racing to make pause-and-resume native rather than bolted on, and dedicated HITL platforms are emerging.
Risks & limits — Approval gates only work if the human actually reads what they sign off on.
