Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It mentions pagination behavior through the 'page' and 'per_page' parameters and filtering via 'active_only', which adds useful context. However, it doesn't disclose rate limits, authentication needs, or whether this is a read-only operation (though implied by 'List'), leaving some behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
