Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, which is consistent. The description adds context that the response is 'concise' and 'public', and lists expected fields. However, it does not disclose additional behavioral aspects like response format, pagination, or authentication requirements beyond 'public'. With annotations present, the added value is moderate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
