Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It states that the tool returns data and lists the data categories, but it does not disclose potential rate limits, authentication requirements, or behavior on invalid inputs. This is adequate but minimal for a read-only data retrieval tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
