About this skill

What it does. Reads CSV, Excel, JSON or SQL results, checks cohort fields and data quality, then calculates retention, engagement, adoption and period-over-period changes. Produces heatmaps, progression charts, pattern findings, reusable pandas and numpy scripts on request, and follow-up research recommendations.

When to use it. For comparing user cohorts over time, investigating churn or feature adoption, and finding drop-offs, anomalies or seasonal trends. It works best with a clear cohort definition and multiple time periods.
