Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, which are consistent with a status check. The description adds context about different states (authenticated:true vs pending[] and connect_url), which is useful. However, it doesn't disclose any rate limits, permission requirements, or return format details beyond what's given. Since annotations cover safety profile, a 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
