data-pipeline-quality from hollandkevint/data-product-operator is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hollandkevint/data-product-operator/data-pipeline-quality@v0.1.1Pins v0.1.1 in mdr.lock. Pin the fingerprint instead.

Automated data quality checks for pipelines. Testing pyramids, dbt test patterns, data contracts, circuit breakers, and monitoring. Use when implementing data quality checks, writing dbt tests, defining data contracts, setting up pipeline validation, building automated quality monitoring, or when someone asks "how do I test my data pipeline?" For quality scoring methodology (the 5-dimension rubric), see data-quality-assessment.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Testing Pyramid for Data
Run tests in this order. Cheapest and fastest first:
| Layer | What It Catches | Examples |
|-------|----------------|---------|
| Schema tests (run first) | Structural failures | Column types, not-null, uniqueness, accepted values |
| Business rule tests | Logic errors | Cross-field validation, referential integrity, range checks |
| Integration tests (run last) | System-level drift | Cross-system reconciliation, end-to-end row counts |
Schema tests are cheap. Run them on every pipeline execution. Business rule tests are mid-tier — run them on staging and production. Integration tests are expensive — run them on a schedule (daily or pre-release).
## dbt Test Patterns
**Generic tests** for reusable checks. Apply across models:
```yaml
models:
- name: fct_encounters
columns:
- name: encounter_id
tests: [not_null, unique]
- name: encounter_type
tests:
- accepted_values:
values: ['inpatient', 'outpatient', 'emergency', 'observation']
- name: patient_id
tests:
- relationships:
to: ref('dim_patient')
field: patient_id
```

How to install
mdr add hollandkevint/data-product-operator/data-pipeline-quality@sha256:c5cf4507576b6e18The line at the top of this page pins the label v0.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
