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.

Important: The message must already be sent before sending an urgent notification. You need the message_id from a previously sent message.
