Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It implies a read-only listing operation, but does not explicitly state that it is safe, nor does it describe any filtering behavior, pagination, or side effects. It gives the basic type of action (listing storages) but nothing about how the tool behaves beyond its name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
