Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the burden of behavioral disclosure. It says 'Show', implying a read-only operation, but does not state whether this is safe/non-mutating, what kind of response is returned, or whether there are side effects. It provides minimal behavioral information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
