WHAT IT DOES

What batch_acknowledge_messages does on Agent-Comm-Hub

AI agents use batch_acknowledge_messages to create or update resources in Agent-Comm-Hub — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Agent-Comm-Hub environment.

WHY IT NEEDS A POLICY

Why batch_acknowledge_messages needs a policy

The tool modifies data state by changing message acknowledgment status in bulk across filtered records (by agent_id and time range). This is a Write operation rather than Read (it modifies, not just retrieves) and is reversible (acknowledgment state can theoretically be reset), not Destructive.

From the tool's definition Tool description indicates it performs batch marking of messages as 'acknowledged' (批量确认消息为已处理/标记为 acknowledged), which modifies the state of message records. This is a write operation that updates message metadata reversibly.
