CSV Data Summarizer

This Skill analyzes CSV files and provides comprehensive summaries with statistical insights and visualizations.

When to Use This Skill

Claude should use this Skill whenever the user:

• Uploads or references a CSV file
• Asks to summarize, analyze, or visualize tabular data
• Requests insights from CSV data
• Wants to understand data structure and quality

How It Works

DO NOT ASK THE USER WHAT THEY WANT TO DO WITH THE DATA. IMMEDIATELY AND AUTOMATICALLY:

1. Run the comprehensive analysis
2. Generate ALL relevant visualizations
3. Present complete results

Automatic Analysis Steps:

1. Load and inspect the CSV file
2. Identify data structure - column types, date columns, numeric columns, categories
3. Determine relevant analyses based on what's actually in the data
4. Only create visualizations that make sense for the specific dataset:
   • Time-series plots ONLY if date/timestamp columns exist
   • Correlation heatmaps ONLY if multiple numeric columns exist
   • Category distributions ONLY if categorical columns exist
5. Generate comprehensive output automatically including:
   • Data overview (rows, columns, types)
   • Key statistics and metrics relevant to the data type
   • Missing data analysis
   • Multiple relevant visualizations (only those that apply)
   • Actionable insights based on patterns found

Behavior Guidelines

• Immediately run the analysis script
• Generate ALL relevant charts automatically
• Provide complete insights without being asked
• Be thorough and complete in first response
• Act decisively without asking permission
