Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already carry idempotentHint=true, readOnlyHint=false, and destructiveHint=false, and the description adds 'durable' and 'accessible workspace' as light behavioral context. It does not disclose permission requirements, conflict behavior, or what 'accessible workspace' means operationally, but it does not contradict the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
