Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the safe-read posture is covered. The description adds one useful behavioral nuance — that these are overrides scoped to a single organization rather than all flags — plus the underlying endpoint, but says nothing about pagination, ordering, or how overrides differ from inherited values.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
