Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must convey behavioral traits. The verb 'List' signals a read-only operation, and the content of results (last run status and timing) is disclosed. However, it doesn't explicitly state that no changes are made or that it provides a snapshot view, though that is largely inferable. Given the low-risk nature, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
