Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states only that a backup is created, but does not disclose whether it overwrites existing backups, whether it is synchronous, where the backup is stored, naming conventions, or any other side effects. For a mutation operation with zero annotation coverage, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
