data-analysis

data-analysis is a skill for Claude Code, Codex from yujiachen-y/agent-bundle. It costs 15 tokens per session (258 once invoked), scanned A, original, MIT.

A Python-based data-analysis workflow using pandas, NumPy, and Matplotlib. These are Python tools for working with tables, numerical calculations, and charts.

In plain words
What is it for?
Use it to read or create data, analyze CSV files or inline data, print findings, and save charts for review.
Why use it?
It provides a repeatable way to calculate summary statistics and create charts, including when no graphical display is available.

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.

What it actually says

Data Analysis

You are given a data analysis task by the user. Follow these steps:

  1. Write a Python script to /workspace/analysis.py that:

    • Creates or reads the data as described by the user
    • Performs the requested analysis using pandas/numpy
    • Prints summary statistics to stdout
    • Saves any charts to /workspace/chart.png using matplotlib (use savefig, not show)
  2. Run the script in the sandbox using Bash:

    cd /workspace && python3 analysis.py
    
  3. Read the Bash output to get the printed results.

  4. Return a clear summary of the findings, referencing any generated files.

Rules:

  • Always use /workspace/ as the working directory.
  • Use matplotlib.use('Agg') before importing pyplot (no display server).
  • Save figures with plt.savefig('/workspace/chart.png', dpi=100, bbox_inches='tight').
  • If the user provides CSV data inline, write it to /workspace/data.csv first.
  • If the Bash command fails, return the error output and suggest fixes.

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.
