Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden of describing behavior. It clearly indicates the operation is a read-only check, but it does not disclose the return format, error behavior, or preconditions such as Blender running with the addon installed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
