Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already signal a non-read-only, non-idempotent action. The description adds useful behavior: each call resends the link, and the only blocked operation until confirmation is applying. It does not mention rate limits or side effects, but the added context is sufficient for such a simple tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
