Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, establishing a safe, read-only operation. The description adds that the return type is a pandas.DataFrame and provides the data source URL, but it does not disclose any additional behavioral traits like data freshness, pagination, or network dependencies. This adds modest value beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
