Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to repeat those. However, the description adds no behavioral context beyond the annotations, such as pagination behavior, rate limits, or what the response contains. It is a minimal statement that does not enrich the agent's understanding of the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
