Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description does flag the key destructive trait: it overwrites the current file, and `force` controls that overwrite. It is silent on what happens when force=false and the target exists (refuse? skip?), whether the backup is consumed after restore, and whether the backup must exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
