Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry behavioral context. It signals a read-only list operation and adds the 'configured for the service provider' scoping detail, but it does not disclose return format, pagination, or whether inactive or archived statuses are included. This is reasonable for a simple list but leaves some behavior unstated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
