WHAT IT DOES

What cloudsync_update does on Truenas

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

RISK

Why cloudsync_update is rated Medium

This tool modifies cloud synchronization task settings, which is a reversible write operation. However, cloud sync tasks can influence data replication and storage behavior, making incorrect updates potentially disruptive to backup or sync operations.

From the tool's definition Tool name 'cloudsync_update' indicates modification of existing cloud sync task configuration. Description states 'Update an existing cloud sync task' which involves changing stored configuration parameters rather than deletion.
