What is Human-in-the-Loop for AI Agents?
HITL requires explicit human approval for certain agent actions — particularly high-value or high-risk transactions — providing safety checkpoints within autonomous workflows.
WHY IT MATTERS
Full autonomy for low-risk; HITL for edge cases. Routine operations autonomous, exceptional ones escalate to humans.
Triggers: amount thresholds, unusual recipients, velocity anomalies, policy edge cases.
Challenge is latency — human review adds minutes/hours. Good HITL minimizes frequency while maximizing review value.
HOW POLICYLAYER USES THIS
PolicyLayer supports HITL checkpoints — holding transactions, notifying reviewers, and waiting for approval before proceeding.
