Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false and destructiveHint=false, indicating a non-read-only mutation. The description adds the prerequisite that the call must be active and recording paused, but doesn't disclose behavior when conditions aren't met or any side effects. Given the annotations, this is minimal but acceptable additional context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
