WHY IT NEEDS A POLICY

Why configure_interface_description needs a policy

This tool creates or modifies interface descriptions on network devices through SSH, which is a reversible configuration change. It does not delete data (would be Destructive), execute arbitrary commands (would be Execute), or incur financial obligations (would be Financial). The 'context check' provides some safeguard.

From the tool's definition Tool description states 'Add or change description on interface' which are create/modify operations on network device configurations. The mention of 'POST with context check' indicates it modifies device state.
