Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It mentions what is returned but does not explicitly state the operation is read-only, safe, or has no side effects. It also doesn't clarify what 'session health' means or whether any data is fresh. This is a minimal disclosure, insufficient for a tool with no annotation safety hints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
