Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations show readOnlyHint: false, destructiveHint: false, idempotentHint: false. The description adds an important behavior: returns the collecting link to send round again. With annotations lacking explicit mutation/destructive flags, the description partially compensates by revealing the state-changing action ('reopens'). It does not cover potential side effects (e.g., resets collection, possible data loss) beyond reopening, and annotations contradict nothing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
