Using Data Analysis Skills
Pick the narrowest skill that covers the current task. When the work spans multiple lifecycle stages, start from the orchestrator and let it call the others.
| Situation | Skill |
|---|---|
| An end-to-end project or an ambiguous modeling request | running-decision-grade-data-science |
| Data meaning, joins, labels, or ground truth may be untrustworthy | auditing-data-and-ground-truth |
| Designing splits, feature eligibility, baselines, or comparisons | designing-leakage-safe-experiments |
| A metric dropped, results disagree, or training-serving mismatch | diagnosing-ml-failures |
| Reviewing whether results support a claim or launch decision | validating-models-and-claims |
| Packaging finished work for independent reproduction | shipping-reproducible-results |
Each skill states its own non-goals in its description; respect them. The
orchestrator running-decision-grade-data-science already routes to the
other five at the right lifecycle stage, so do not stack it with them
manually for the same step.
