This one's built for when you need to dig through messy datasets and actually make sense of them. It handles exploratory data analysis, pattern detection, and multi-source data integration, plus it can run statistical tests and build ML models when needed. The skill focuses on turning raw data into something you can actually present to stakeholders with visualizations and narratives. It's got 173 installs and passed most security audits, with a warning from Snyk worth checking. If you're doing serious data work in Claude and need more than basic CSV manipulation, this covers the full research workflow from discovery to insight delivery.
