How do you test an AI agent before it touches real customer data?
A builder asks how to test an agent before giving it access to real customer data. The reliable pattern: test against a small set of made-up customers with known right answers, watch what the agent actually writes back rather than what it claims, and keep a separate verification check between the agent and the customer. Only after the fake set passes clean does the agent get a small slice of real traffic with a human watching.
