WHAT IT DOES

What create_inventory_variant does on Huly

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

RISK

Why create_inventory_variant is rated Medium

This tool creates and adds new inventory data (product variants or SKUs), which is a reversible write operation. It modifies product catalogs by introducing new variant records. While inventory creation can have business impact, it is not irreversible (variants can be edited or removed), not destructive, and not financial.

From the tool's definition Tool description states 'Create an inventory variant/SKU' — the verb 'Create' explicitly indicates data creation. The tool adds new inventory records (variants/SKUs) to a product.
