Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, and the description does not contradict this. The description adds the context that the tool is 'Free', which is useful but not deeply revealing. It does not describe what happens during enhancement, whether it requires specific inputs, or what the output format is. With annotations covering the safety profile, the description adds some but limited behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
