## Why request_customer_merge is rated Medium

Merging customers combines records including order history and addresses. While potentially reversible in some systems, customer merges are typically difficult to undo and have significant blast radius — merging the wrong customers could corrupt order history and customer data across a store.

From the tool's own definition: "Merge one customer into another (combines order history, addresses, etc.)"

## Use case

AI agents use request_customer_merge 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.
