Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states the tool returns data (implying read-only), but does not disclose any behavioral traits such as data recency, pagination, latency, or authentication requirements. The word 'active' hints at state filtering but lacks elaboration.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
