WHY IT NEEDS A POLICY

Why gateway_add_route needs a policy

The name strongly implies creating or modifying a route in a gateway configuration, which is a reversible Write operation. However, with no description provided, confidence is reduced. If this route controls access to sensitive systems or can be used to redirect traffic maliciously, severity could escalate to high.

From the tool's definition Tool name 'gateway_add_route' suggests adding a route to a gateway (likely network/API routing). The 'add_' prefix indicates a create/modify operation. Description is empty, limiting certainty.
