WHY IT NEEDS A POLICY

Why snow_create_entitlement needs a policy

This tool creates a new service entitlement, which is a write operation that generates a new record in ServiceNow. It is reversible (can be deleted), so it does not qualify as Destructive. However, it has high severity because creating entitlements can affect customer billing, SLA obligations, and support terms—misuse by an AI agent could commit unintended service obligations.

From the tool's definition Tool name contains 'create' and description states 'Create service entitlement for customer', indicating irreversible creation of a new business entity with contractual implications.
