// WHEN AI AGENTS USE THIS TOOL

AI agents may call pylon_delete_webhook to permanently remove or destroy resources in Pylon Server. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

// WHY ENFORCE A POLICY ON PYLON_DELETE_WEBHOOK

Without a policy, an AI agent could call pylon_delete_webhook in a loop, permanently destroying resources in Pylon Server. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

// RECOMMENDED POLICY
