Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered structurally. However, the description adds nothing beyond them — it does not say whether the deletion is permanent or recoverable, what happens if the noteId is unknown or already deleted (relevant given idempotency), or what is returned. For a destructive operation this leaves real behavioral questions unanswered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
