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. It states that the tool 'returns' data, implying a read-only operation, but does not disclose any side effects, data characteristics, or potential limitations. There is no mention of pagination, freshness, or other behavioral traits beyond the return of categories and counts.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
