Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds a genuine data-scope constraint ('metadata/approved fields only; no secrets, contacts or original files'), which is useful behavioural context, but it says nothing about pagination behaviour or what a 'status' response contains.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
