RISK

Why stateset_add_cart_item is rated Medium

This tool creates or modifies shopping cart data reversibly. It does not execute arbitrary code, delete data irreversibly, or move money directly. While cart operations can lead to financial transactions downstream, the tool itself only performs a write operation (adding/updating cart items).

From the tool's definition Tool description states 'Adds an item to a shopping cart' and 'quantity is added', indicating it modifies cart state by creating or updating cart entries.
