Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations (readOnlyHint=true, destructiveHint=false, idempotentHint=true) already indicate a safe, non-destructive operation. The description adds no additional behavioral traits such as authentication needs, rate limits, or return format. With annotations covering safety, this scores a baseline 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
