Approval Gating

import { ApprovalGate } from 'arclet';

const approvalGate = new ApprovalGate({
  requireApprovalFor: ['delete_database', 'execute_payment'],
  async onApprovalRequested(action) {
    console.log(`[APPROVAL REQUIRED]: Tool ${action.toolName} needs human confirmation.`);
    // Return false to reject, or pause and ask the user
    return false; 
  },
});

const agent = new AgentBuilder()
  .name('SecureAgent')
  .llm(adapter)
  .approvalGate(approvalGate)
  .build();
