Why upsert_product_brand is rated Medium
The upsert_product_brand tool creates or updates product brand data within a storefront system. This is a write operation that modifies data, but changes are reversible (brands can be edited or deleted later). While it affects storefront content, it does not execute arbitrary code, delete data irreversibly, or move money. The blast radius is limited to brand metadata within the catalog, making it medium severity.
From the tool's definition Tool name 'upsert_product' and description 'Create or update a product brand' indicate reversible data modification operations.
