Human-in-the-Loop Patterns

Insert human judgment at explicit risk and uncertainty boundaries.

Human Oversight Is an Architecture Pattern

"A human is involved" is not enough. The system must define when the human is asked, what evidence is shown, what decision is available, and what happens after approval, rejection, correction, timeout, or escalation.

Common Intervention Patterns

Pattern	Best use
Pre-execution approval	Irreversible, financial, external, or privileged actions
Editable plan	Long-running work where direction matters before execution
Exception queue	Low-confidence or policy-sensitive cases
Post-execution sampling	Low-risk, high-volume quality monitoring
Human takeover	Ambiguous, emotional, legal, or safety-critical interactions

Design the Review Experience

Show the proposed action, supporting evidence, expected impact, alternatives, and a clear diff. Avoid approval fatigue: if reviewers approve hundreds of meaningless prompts, the control becomes ceremonial.

Automation bias

A human click is not proof of safety. Reviewers need enough time, context, authority, and an easy way to reject or edit the proposal.

Key Takeaways

Human-in-the-loop requires explicit triggers, evidence, decisions, and follow-up transitions.
Place approval before high-impact actions and use sampling for low-risk monitoring.
Design against approval fatigue and automation bias.

When is pre-execution approval most appropriate?

What makes an approval control weak?
