What is Snowflake Cortex Code?

CoCo is Snowflake's AI agent in Snowsight that turns natural language prompts into executed SnowSQL for tasks like PII classification, tagging, and masking — all in one go.

How does Snowflake Cortex Code handle PII automatically?

It classifies data with SYSTEM$CLASSIFY, applies PII tags in batch, creates role-based masking policies, and chains them smoothly under your privileges.

Will Snowflake CoCo replace data engineers?

Nah — it handles boilerplate, freeing them for architecture and strategy. Think power tool, not replacement.
