Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations include openWorldHint: true, which indicates the tool may return data outside a predefined closed world, but the description does not contradict this. The description mentions 'price per run' which is useful operational context. However, the description does not disclose other behavioral traits such as the return format (though an output schema exists), whether pagination is supported (it is, via page and limit parameters, but those are also documented in the schema), or any potential side effects. Given the positive annotation, the description adds context about pricing, which is helpful but not extensive. The lack of behavioral disclosure beyond the schema and pricing keeps this at a moderate 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
