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 only states that the tool lists items, implying a read-only operation, but does not mention pagination, authentication, rate limits, or any side effects. The limit/offset parameters are not explained, so the behavior remains opaque.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
