Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read only (readOnlyHint=true), non-destructive, idempotent, and open world. The description adds that workspace ID is required and lists returned fields, but does not significantly expand on behavioral traits beyond what annotations convey.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
