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 adds useful details: newest-first ordering, included status/progress fields, and the required read scope. However, it does not describe pagination behavior, empty-result behavior, or any other response characteristics beyond those fields.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
