This tool creates or modifies data reversibly by updating order fields such as quantity or status. It does not delete data (which would be Destructive), execute arbitrary code (Execute), or move money (Financial). The blast radius is medium because incorrect updates could affect order fulfillment workflows, but changes are reversible through subsequent updates.

From the tool's definition Tool name 'order_update' and description 'Update fields on an order (e.g., quantity or status if present)' indicate modification of existing data records.
