WHAT IT DOES

What move_fulfillment_order does on Shopify Graphql

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

WHY IT NEEDS A POLICY

Why move_fulfillment_order needs a policy

This tool updates fulfillment order metadata (location assignment) in a reversible manner. While it affects order logistics, the change is not irreversible and does not execute arbitrary commands or incur financial transactions.

From the tool's definition move_fulfillment_order modifies fulfillment order state by relocating it to a different location, which is a reversible data modification operation. The action changes fulfillment routing/location assignment but does not delete data or execute arbitrary code.
