WHY IT NEEDS A POLICY

Why set_backup_schedule needs a policy

This tool modifies system backup settings, which is a reversible write operation (schedule can be changed again). It does not irreversibly delete data (Destructive), execute arbitrary code (Execute), or move money (Financial). The lack of description prevents full confidence, but 'set_' actions on configuration are Write-category.

From the tool's definition Tool name 'set_backup_schedule' indicates creation or modification of a backup configuration. The suffix 'set_' suggests state-changing operation rather than retrieval.
