Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds minimal extra behavior context, such as that it lists jobs tied to a resource, but does not disclose any further details like pagination or return format. This meets the lower bar set by the annotations without contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
