Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It only states that events are searched by name; it does not reveal whether the operation is read-only, how results are returned (full objects vs. summaries), case sensitivity, pagination, or limits. This is a significant gap for a search tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
