Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish that this is a safe read-only operation. The description adds useful behavior beyond that: newest-change-first ordering, who changed items, whether they changed since last viewed, and file type/size, but it does not mention limits or auth/rate-limit behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
