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. It adds that the tool returns all properties, which is useful context, but does not disclose potential errors, authentication requirements, or response structure. The behavior is simple and mostly self-explanatory, so a mid-range score is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
