Feishu Urgent Tool

Single tool feishu_urgent for sending urgent (buzz) notifications to recipients for an already-sent message.

Overview

Urgent notifications (also called "buzz" in Feishu) send a strong push notification to specified recipients. Use this to escalate important messages that require immediate attention.
