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. 'Gets' implies a read-only operation, but the description does not clarify what the returned settings look like, whether defaults are included, or how authentication/authorization behaves beyond the vague 'authenticated account' phrasing. It is not contradictory, but it is thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
