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 read operation. The description adds that it's a 'GET' method, which aligns with read-only behavior and doesn't contradict annotations. However, it doesn't disclose additional behavioral traits like authentication requirements, rate limits, or what 'current plan' refers to in context. With annotations covering safety, the description adds minimal value beyond method type.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
