Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses the return structure via an output schema and describes parameter effects. However, it does not mention any behavioral traits such as permissions, rate limits, or side effects (though the tool is read-only, this is not explicitly stated).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
