The Data Layer Your Agents Actually Need: Snowflake, dbt and Contracts

Agentic systems amplify data quality — in both directions. Contracts and lineage are what keep them honest.

Every autonomous system is a consumer of your semantic layer. If a metric has three definitions, your agent will confidently pick the wrong one and defend it.

dbt gives you tested, versioned transformations; Snowflake gives you elastic compute and governance. Together they let you expose a small, curated surface to agents rather than raw warehouse sprawl.

Add data contracts at the boundary — schema, nullability, freshness SLA. Break the build, not production.

Then expose that layer through a typed tool interface. Agents should query metrics, not tables.
