Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds useful data-scope context ('metadata/approved fields only; no secrets, contacts or original files'), but it does not describe pagination behavior, return format, or authorization requirements beyond 'authorised'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
