Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds valuable context beyond annotations: return fields under different conditions (authenticated vs. missing credentials) and the presence of pending[] and connect_url. It does not mention any side effects or rate limits, but none are expected for a read-only status tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
