Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries full behavioral burden. It does disclose the return type ('message indicating whether Hunyuan3D features are available') and frames this as a non-mutating check. However, it doesn't clarify whether the function ever enables anything, what happens if Blender isn't running, or what the message structure looks like. Acceptable baseline disclosure, but with no annotations, more depth would help.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
