Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the disclosure burden. It does add two useful behavioral facts: results are limited to 100 and the data is cross-border-scoped. However, it does not state whether the operation is read-only, what happens if more than 100 statuses exist, whether pagination is available, or what the response shape is.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
