Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the disclosure burden. It clearly indicates a read operation via 'Get' and names the returned data categories, but it does not disclose behavior such as time range, aggregation method, permissions, or whether the data is live or cached. This is minimal but not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
