Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only states the action without mentioning creation side effects, prerequisites, defaults, or expected behavior. There is no information about what happens upon success, failure, or how the node is created within the Houdini scene.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
