WHAT IT DOES

What upsert_product_tag does on Webcake Storefront

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

RISK

Why upsert_product_tag is rated Medium

The tool creates new product tags or modifies existing ones. Both operations are write actions that can be undone (tags can be deleted or re-edited). This does not destroy data irreversibly, execute arbitrary code, or move money, so it falls under Write category. Severity is medium because misuse could corrupt product taxonomy or confuse store organization, but the impact is confined to metadata and reversible.

From the tool's definition Tool name includes 'upsert' (create or update); description states 'Create or update a product tag.' These are reversible write operations.
