Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, establishing a safe read operation. The description adds behavioral specifics beyond annotations: it details the exact return values in two scenarios (authenticated:true with empty pending[] when connected; connect_url and per-install URLs when credentials are missing). No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
