WHY IT NEEDS A POLICY

Why snow_create_sla needs a policy

Creating SLAs is a reversible write operation that establishes new business rules and service level commitments in ServiceNow. While reversible (SLAs can be deleted or modified), it carries high severity due to the operational impact of incorrectly configured SLAs—they can affect incident response timelines, escalation policies, and business continuity across the enterprise.

From the tool's definition Tool name 'snow_create_sla' and description 'Create Service Level Agreement' indicate creation of a new SLA record in ServiceNow, which modifies the system state by adding a new entity.
