What problem does it solve?

This Skill turns raw tables into reproducible data analysis, helping you verify schema, grain, quality, and metrics before drawing conclusions.

Core Features & Use Cases

  • Exploratory analysis: Profile CSV, Excel, JSON, and Parquet data with missingness, duplicates, types, and distribution checks.
  • Metric and KPI analysis: Compute grouped summaries, YoY or MoM changes, funnels, cohorts, and time-series trends with explicit denominators.
  • Hypothesis-driven investigation: Validate root-cause hypotheses, compare segments, and produce evidence-backed findings with clear limitations.
  • Use Case: If sales dropped last month, use this Skill to confirm the data grain, audit the dataset, test plausible drivers, and write a findings summary that is fully traceable.

Quick Start

Ask the assistant to analyze your dataset with this skill and it will profile the file, verify grain and quality, compute the relevant metrics, and produce a reproducible findings summary.
