I Told Snowflake’s AI to Find Our Hidden PII. It Did More Than That

What happens when a single prompt triggers classification, tagging, and masking - all before your coffee gets cold. Persona: Presto, a data engineer at a mid-size fintech. Two hundred tables. One compliance audit in three weeks. Zero desire to write boilerplate SQL on a Friday afternoon. The prompt that started everything Presto, opened Cortex Code (CoCo) inside Snowsight and typed: “Classify the CUSTOMERS table, tag anything sensitive, and create a masking policy so only DATA_ENGINEER sees real PII. Everyone else gets masked values.” One sentence. That was it.
