WHY IT NEEDS A POLICY

Why create_department needs a policy

Creating a new department is a reversible write operation. It modifies the 3CX organizational structure by adding a new entity, but the action can be undone by deleting the department. This does not meet the threshold for Destructive (which requires irreversible deletion/overwrite) or Execute (which requires running arbitrary code or commands).

From the tool's definition Tool name 'create_department' and description 'Creates a new department (group) in 3CX. Returns the created department with its assigned Id' indicate data creation.
