Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description does add the key behavioral fact that saving writes the edited scene to disk, which the annotations alone do not fully convey. It does not, however, explain overwrite behavior, failure modes, or whether saving with a new path changes the active scene's path, though the schema covers some of this.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
