data-analysis

data-analysis is a skill for Claude Code, Codex from femto/minion. It costs 9 tokens per session (549 once invoked), scanned A, original, MIT.

A data-analysis tool for loading CSV files, examining their contents, calculating statistics, and creating charts such as line, bar, and scatter plots.

In plain words
What is it for?
Use it to inspect datasets, calculate descriptive statistics and correlations, find outliers, and save charts or analysis results.
Why use it?
It organizes common data-checking and analysis steps, including missing values, unusual values, and relationships between columns.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

data-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Data Analysis Skill

Description

This skill helps analyze datasets and create meaningful visualizations. It can handle CSV files, perform statistical analysis, and generate various types of plots.

Usage Instructions

When a user requests data analysis:

  1. Load the dataset: Use pandas to read the data file
  2. Inspect the data: Check shape, columns, data types, and basic statistics
  3. Clean the data: Handle missing values and outliers if necessary
  4. Perform analysis: Calculate relevant statistics based on user's question
  5. Create visualizations: Generate appropriate plots (line, bar, scatter, etc.)
  6. Save results: Export results and visualizations

Available Resources

Scripts

  • scripts/analyze.py: Core analysis functions

    • load_dataset(filepath): Load data from various formats
    • basic_statistics(df): Calculate descriptive statistics
    • detect_outliers(df, column): Identify outliers
    • correlation_analysis(df): Compute correlations
  • scripts/visualize.py: Visualization utilities

    • plot_distribution(df, column): Create distribution plots
    • plot_correlation_matrix(df): Visualize correlation heatmap
    • plot_time_series(df, date_col, value_col): Time series plots
    • save_plot(fig, filename): Save figure to file

References

  • references/examples.md: Usage examples and common patterns
  • references/best_practices.md: Data analysis best practices

Example Prompts

  • "Analyze this CSV file and show me the trends"
  • "Create a visualization of the sales data by month"
  • "Find correlations in this dataset"
  • "Identify outliers in the price column"
  • "Generate a statistical summary of the data"

Output Format

Analysis results should include:

  1. Data overview (shape, columns, types)
  2. Statistical summary
  3. Key insights and findings
  4. Visualizations (saved as PNG files)
  5. Recommendations or next steps

Notes

  • Always inspect data before analysis
  • Handle missing values appropriately
  • Choose visualizations that match the data type
  • Provide clear explanations of findings
  • Save all outputs for user reference

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
