Delete a custom pixel
AI agents call delete_custom_pixel to permanently remove resources in Shopify Graphql — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a custom pixel from a Shopify store, which is an irreversible action. While the blast radius is limited to a single pixel configuration (not store-wide data), the destructive nature and inability to undo the action places it in the Destructive category.
From the tool's definition Tool name 'delete_custom_pixel' and description 'Delete a custom pixel' explicitly indicate irreversible deletion of data. The verb 'delete' is a destructive operation that cannot be undone.
