WHY IT NEEDS A POLICY

Why create_channel needs a policy

Creating a sales channel is a Write operation as it adds new configuration to the Shopify store. While it modifies store structure, it is not destructive (can be undone by removing the channel) and does not involve financial transactions or code execution.

From the tool's definition Tool description states "Create a new sales channel" - a create operation that modifies store configuration by adding a new sales channel. This is a reversible write operation (channels can typically be deleted/disabled).
