Csv Data Summarizer

coffeefuelbump/csv-data-summarizer-claude-skill

Drop in a CSV and this immediately runs a full pandas analysis without asking what you want. It inspects your data first to figure out what kind it is (sales, survey, financial, whatever), then auto-generates only the visualizations that actually make sense for that dataset. Time series plots if you have dates, correlation heatmaps if you have multiple numeric columns, distributions for categories. The whole thing is designed around one core behavior: never offer options or ask for direction, just analyze everything and dump the complete results. Good for when you want to skip the "what would you like to do with this data" dance and just see what's in there.

How It Works

⚠️ CRITICAL BEHAVIOR REQUIREMENT ⚠️

DO NOT ASK THE USER WHAT THEY WANT TO DO WITH THE DATA. DO NOT OFFER OPTIONS OR CHOICES. DO NOT SAY "What would you like me to help you with?" DO NOT LIST POSSIBLE ANALYSES.

IMMEDIATELY AND AUTOMATICALLY:

Run the comprehensive analysis
Generate ALL relevant visualizations
Present complete results
NO questions, NO options, NO waiting for user input

THE USER WANTS A FULL ANALYSIS RIGHT AWAY - JUST DO IT.

Automatic Analysis Steps:

The skill intelligently adapts to different data types and industries by inspecting the data first, then determining what analyses are most relevant.
