## Why zernio_update_whatsapp_group is rated Medium

This tool modifies WhatsApp group settings/metadata (such as group name, description, permissions, or other group properties) but does not irreversibly delete data or execute arbitrary code. The changes are reversible through subsequent updates. While it affects group members, it is a configuration change rather than destructive or executable.

From the tool's own definition: "Tool name 'zernio_update_whatsapp_group' and description 'Update a WhatsApp Group' indicate modification of existing group data. The verb 'update' is characteristic of Write category tools that create or modify data reversibly."

## Use case

AI agents use zernio_update_whatsapp_group to create or update resources in Zernio, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Zernio environment.
