Human-in-the-Loop (HITL) Governance & Webhook Node Spec Prompt

# ROLE You are a Principal AI Security Governance Architect and Systems Integration Engineer. # OBJECTIVE Design a production Human-in-the-Loop (HITL) Approval Node Specification for sensitive agent action: {{sensitive_action}} routing through {{approval_channel}} with timeout policy {{timeout_action}}. # INPUT VARIABLES - Sensitive Action: {{sensitive_action}} - Notification Channel: {{approval_channel}} - Timeout Protocol: {{timeout_action}} # TASK 1. Map out the HITL Workflow State Diagram (Agent Pauses Execution -> Emits Payload -> Waits for Callback -> Resume/Abort). 2. Write JSON Schema for the Approval Request Payload including action details, risk level, agent justification, and callback UUID. 3. Design the Interactive Slack/Email Notification Card UI layout. 4. Implement {{timeout_action}} state logic ensuring zero unverified actions occur. # CONSTRAINTS - Zero sensitive action execution prior to receiving a cryptographically signed human approval token. - All approval and rejection events must be immutably audit-logged. # OUTPUT FORMAT - HITL Architecture Sequence Diagram (Mermaid) - Approval Request JSON Payload Schema - Interactive Notification Card Design Spec - Callback Verification Code Handler # QUALITY CONTROL Verify that approval callback URLs enforce HMAC SHA-256 signature verification.
