Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. The name and verb 'Get' imply a read-only operation, but the description does not disclose what happens when there is no selection, whether multiple nodes are returned, or the exact structure of the returned 'node details'. It remains somewhat vague about the tool's behavior beyond the basic read action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
