data-analysis

A toolset for working with tabular data in CSV, Excel, and similar files. It supports analysis, cleaning, transformations, statistics, charts, and summary reports.

In plain words
What is it for?
Use it to load and clean datasets, calculate summaries, create visualizations, and produce reports from spreadsheet-like data.
Why use it?
It reduces the manual work needed to understand structured data and present its main patterns. The input does not describe any more specialized capabilities.

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 yesterday.

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.

What it actually says

Data Analysis

When to use this skill

Use this skill when the user needs to:

  • Analyze CSV or Excel files
  • Generate charts and visualizations
  • Calculate statistics and summaries
  • Clean and transform data

How to analyze data

  1. Use pandas for data analysis:
    import pandas as pd
    df = pd.read_csv('data.csv')
    summary = df.describe()
    

How to create visualizations

  1. Use matplotlib or seaborn for charts:
    import matplotlib.pyplot as plt
    df.plot(kind='bar')
    plt.savefig('chart.png')

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.

data-analysis is a skill published in the GitHub repository kitproj/coding-context-cli (4 stars, last pushed 3mo ago), licensed MIT. It adds 37 tokens to every session and 176 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
