HITL pauses the agent at a decision point for human review before proceeding — used for high-stakes actions. In an enterprise AI platform: Step Functions Wait for Callback pattern — agent sends a task token to a review queue (SQS/SNS), human approves via UI, UI calls SendTaskSuccess/Failure with token, agent resumes. In a resume screening system: low-confidence candidates route to HITL before final scoring.
