Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It discloses that the search is free-text/semantic, includes past events, and supports offset pagination. However, it omits behavioral traits such as authentication needs, rate limits, result sorting, or handling of empty queries, leaving gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
