Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the entire burden. It only states that the tool searches two named sources; it does not disclose result format, pagination, failure modes, freshness, or whether the search is live or cached. 'Search' implies read-only behavior, but little else is transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
