Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the safety profile is established. The description adds minimal behavioral context beyond the word 'durable', indicating persistence of notes, but does not disclose anything else such as ordering, limits, or relationship to the notepad store.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
