Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, indicating a safe, repeatable operation. The description adds that it's a GET method, which is consistent with read-only behavior, but doesn't disclose additional traits like rate limits, authentication needs, or what 'addWorker' entails beyond the method. No contradiction with annotations exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
