Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, so the tool is known to be non-destructive. The description adds no additional behavioral context—no mention of side effects, permissions, rate limits, or response specifics. It simply restates the purpose, providing no value beyond the structured annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
