Interface: IHumanInteractionManager

Defined in: packages/agentos/src/orchestration/hitl/IHumanInteractionManager.ts:413

Interface for the AgentOS Human-in-the-Loop Manager.

The HITL Manager enables structured collaboration between AI agents and human operators, ensuring human oversight for critical decisions while maintaining efficient autonomous operation.

Key capabilities:

  • Approval Requests: Seek human approval for high-risk actions
  • Clarification: Ask humans to resolve ambiguity
  • Output Review: Have humans review and edit agent outputs
  • Escalation: Transfer control when agents are uncertain
  • Checkpoints: Regular human review of ongoing work
  • Feedback Loop: Learn from human corrections

Example​

const hitl = new HumanInteractionManager({
  notificationHandler: async (req) => {
    // Send to UI/Slack/email
    await notifyHuman(req);
  },
  defaultTimeoutMs: 300000, // 5 minutes
});

// Register response handler
hitl.onApprovalResponse((decision) => {
  console.log(`Action ${decision.actionId}: ${decision.approved ? 'Approved' : 'Rejected'}`);
});

// Request approval
const decision = await hitl.requestApproval({
  actionId: 'send-mass-email',
  description: 'Send promotional email to 10,000 subscribers',
  severity: 'high',
  context: { recipientCount: 10000, template: 'promo-q4' },
  reversible: false,
});
