Human-in-the-Loop

Why HITL Matters

Human oversight matters when an action is uncertain, consequential, hard to reverse, or regulated:

• Agents hallucinate actions — misinterpret prompts and overstep boundaries
• Mistakes scale instantly — autonomous errors cascade across systems
• Regulations require it — EU AI Act mandates human oversight for high-risk AI
• Trust is earned — users build confidence gradually, not overnight

Oversight does not guarantee success; it creates a decision boundary where a qualified reviewer can stop, correct, or defer a risky action.

HITL Patterns

Approval Gate

Agent proposes, human approves before execution:

async def execute_with_approval(action, risk_level):
    if risk_level == "high":
        # Block until human approves
        approval = await request_human_approval(
            action=action,
            context=get_full_context(),
            timeout="24h"
        )
        if not approval.granted:
            return ActionResult(status="rejected", reason=approval.reason)

    return await execute(action)
