## Why stateset_add_order_item is rated Medium

This tool creates new order line items, which modifies existing data but is reversible (items can be removed or orders cancelled). The blast radius is moderate—an agent could add incorrect items or quantities to orders, causing customer confusion or financial discrepancies, but the operation itself doesn't permanently destroy data or trigger irreversible financial transactions.

From the tool's own definition: "Tool description states it 'Adds a new item to an existing order', which is a reversible modification operation."

## Use case

AI agents use stateset_add_order_item to create or update resources in Stateset, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Stateset environment.
