Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation already indicates a safe read operation, and the description's 'Get' is consistent with that. No additional behavioral context (e.g., output format, pagination, rate limits) is provided, but for a simple lookup, the annotation covers the primary safety concern.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
