Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only says 'get comprehensive information' without indicating whether the operation is read-only, what data is included, or any potential side effects. The description does not contradict annotations since there are none, but it fails to provide meaningful 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.
