Human-in-the-Loop (HITL) is a deliberate architectural strategy used to mitigate risk by placing human reviewers at specific, defined checkpoints in an agentic workflow.
Core Principle
- Not a fallback of last resort: HITL should be an integrated part of the system design to handle high-stakes decisions.
- Targeted, not ubiquitous: Effective HITL is applied to checkpoints where the cost of failure is high or where human judgment is essential to policy alignment, rather than applied to every interaction.
