Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds no behavioral context beyond what the schema and annotations provide; 'by ID' simply restates the required parameter. No details about return format, error behavior, or scope are disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
