WHY IT NEEDS A POLICY

Why save_config needs a policy

The 'save_config' tool likely persists configuration changes to network devices managed through HPE Aruba Networking Central. While the description is empty, the context of a network management platform and the name strongly suggest this creates or modifies persistent configuration state. This is Write rather than Destructive because configuration saves are typically reversible through backups or rollbacks.

From the tool's definition Tool name 'save_config' combined with server description indicating 'configuration management' functionality. Sibling tools include 'backup_config' and 'bounce_interface' which suggest Write-category operations on network infrastructure.
