Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, and the description repeats the read-only guarantee. It adds useful scope detail ('Only pages the founder shared...'), but does not explain result ordering, pagination, auth expectations, or open-world behavior beyond the annotation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
