Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile: readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true. The description adds that listing is scoped to a named bulk dataset, but does not disclose return format, pagination behavior, authentication needs, or dataset-name discovery.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
