What frameworks does this skill support?

It integrates with Pydantic for record-level validation, Pandera for DataFrame schemas, and Great Expectations for pipeline monitoring and data warehouse checks.

Can I use this for custom business rules?

Yes, the skill includes patterns for custom business rules through validators like date range checks, value set validation, and referential integrity functions.

Is this suitable for production ETL tasks?

Yes, it is specifically designed for data engineers building production-grade validation pipelines that require monitoring and strict schema enforcement.

How do I implement a configuration-driven pipeline?

You can use the 'run_validation_pipeline' function which accepts a configuration dictionary defining unique columns, date ranges, and other constraints.

Does it support automated testing?

Absolutely. It includes a suite of test assertions (e.g., assert_schema_match, assert_no_nulls) designed to be used within frameworks like pytest.
