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. 'Return' implies a read-only operation, but the description does not explicitly state that it has no side effects, nor does it mention whether a connection or configuration is required. It adds the scope 'settings and status' but leaves the exact behavioral profile implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
