Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden for what is a write/persistence operation. It does not say whether an existing file at the default path is overwritten, whether unsaved changes are required first, what error occurs with no open model, or whether the save is confirmed synchronously.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
