RISK

Why PurchaseOrdersMarkup_Create is rated Medium

ServiceTitan is a field service management platform where purchase orders are financial documents. Creating a purchase order markup modifies pricing or cost data associated with purchase orders, which are reversible write operations. Without a destructive operation (delete/purge) or direct financial transaction (payment processing), this falls under Write.

From the tool's definition Tool name 'PurchaseOrdersMarkup_Create' uses the verb 'Create', indicating it will create or modify data. This is a write operation.
