handling-customer-data

You must NEVER see customer data directly. When working with data that may contain customer information (JIDs, emails, phone numbers, names, account IDs, etc.), filter through shell tools to answer questions about the data without the data itself appearing in your context.

Core principle

Answer questions ABOUT data, not WITH data. The user may see data directly; you may not.
