What is Decision Data Analysis?

ZhengFangrong/data-analysis-skill is a decision-first analytics skill for agents. Upload Excel/CSV and ask a business question—it covers anomaly detection, funnels, metrics systems, AB tests, causal inference, segmentation, contribution breakdowns, attribution, cohorts, retention, paths, RFM, and more, then ships an offline HTML report. Vague asks get grilled before analysis.
