Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Search' implies a read-only action, but the description does not state whether results are summaries or full documents, how results are ordered, whether pagination exists beyond the limit parameter, or any access expectations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
