Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It does convey that the tool returns only unresolved failures and frames them as the current 'do not repeat' set, but it does not mention read-only behavior, ordering, pagination, or response shape. This is adequate but not rich for a no-annotation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
