Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden of behavioral disclosure. It communicates what information is returned, but does that not explicitly state that the operation is read-only or has no side effects, although the get_ prefix suggests this and the tool is a trivial no-parameter read.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
