WHY IT NEEDS A POLICY

Why create_purchase_order needs a policy

This tool creates new purchase orders, which are reversible write operations (purchase orders can be modified or cancelled). While purchase orders involve financial commitments, the tool itself does not execute payments or irrevocably transfer funds—it creates the order record. This places it in Write rather than Financial.

From the tool's definition Tool name 'create_purchase_order' and description 'Create a new purchase order' indicate creation of a financial/procurement document that commits organizational resources. Requires 'manager role' access control.
