Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds no behavioral context beyond the title. Annotations already indicate readOnlyHint=false and destructiveHint=false; the description does not disclose any additional traits such as auth requirements, effects on the topic, or post creation limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
