RISK

Why get_stream_object is rated Low

This tool retrieves metadata or details about an existing stream object in Google Cloud Datastream without modifying, deleting, or executing any operations. It is a straightforward data retrieval operation with no side effects, fitting the 'Read' category. The blast radius of misuse is minimal since it only exposes existing data that the agent may already be authorized to view.

From the tool's definition Tool description states 'Get details of the stream object' - a retrieval operation with no modification or deletion. The name 'get_stream_object' and description explicitly indicate a read-only query operation.
