WHY IT NEEDS A POLICY

Why urwa_is_kill_switched needs a policy

The name implies a status check (Read), but 'kill switch' could also imply a state change or destructive capability. With no description, confidence is low. Given the financial/critical context of the server (wallet, payments, staking), even a read on a kill switch could have significant implications, but without evidence of action, defaulting to Read with medium severity.

From the tool's definition Tool name 'urwa_is_kill_switched' suggests checking a kill switch status (a read/query operation), but the description is empty and uninformative.
