Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation already declares this as a safe read operation, and the description's 'Get' is consistent with that. However, the description adds no additional behavioral context beyond what the annotation provides, such as the scope of 'main settings' or any response characteristics, though this is partially mitigated by the output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
