Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=false and destructiveHint=false, so the description is not contradicting them. The description adds the constraint that 'file' must be an absolute path, which is useful behavioral context. However, it does not disclose what happens if the file does not exist, whether the current scene is replaced, or any side effects on the scene state.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
