Data Testing Skill

Designs data testing strategies, generates SQL assertions, validates pipeline output, and packages test suites as client deliverables. Produces test code and configurations; does NOT execute tests against live data.

When to Use This Skill

Activate when: Designing test strategies for data pipelines, writing SQL assertions for data quality, validating dbt model output, setting test coverage targets, building regression test suites, comparing pre/post migration data, or packaging test results as client deliverables.

Don't use for:

• Writing or modifying dbt models → use dbt-transforms
• Running DuckDB analytical queries without testing intent → use duckdb
• Scheduling or orchestrating test jobs → use data-pipelines
• Production monitoring or alerting on data freshness → use data-observability
