Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the base safety profile is covered. The word 'all' in the description adds slight context about the scope (returns the full list), but no other behavioral traits (e.g., pagination, ordering, or potential performance implications) are disclosed. The description does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
