Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds useful behavior beyond that: results are alphabetical, paginated at 50 per page by default, and each row carries price and last edit time. Auth/clinic-scoping behavior is left to the schema's clinicId field rather than explained here.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
