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 mentions 'historical' data and 'per day' aggregation, which adds some context, but fails to detail critical aspects like whether the data is read-only, if authentication is required, rate limits, or the format of returned data. For a tool with no annotations, this leaves significant gaps in understanding its behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
