Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden, and it discloses nothing: not whether the call is read-only, whether it depends on a session/active address, what happens on failure, or what the response contains. The only hint about behavior is the notification_message parameter, which is documented in the schema rather than the description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
