Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the tool's safety is clear. The description adds no additional behavioral context such as rate limits, auth specifics, or side effects. It provides return field examples, but with an output schema, this is redundant.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
