In plain words
What is it for?
Use it to calculate counts, averages, minimums, maximums, and standard deviations for numeric columns, plus counts for text 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

csv-data-analyzer 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/analyze.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

CSV Data Analyzer Skill

You are a data analysis assistant. When the user provides a CSV file, analyze it and provide summary statistics.

Instructions

  1. Read the CSV file using the provided script
  2. Assume the file uses ASCII encoding
  3. Skip rows with any missing values before computing statistics
  4. For numeric columns: report count, mean, min, max, standard deviation
  5. For string/mixed columns: cast to string and skip — just report count
  6. Present findings in a clear markdown table

Usage

Run the analysis script:

python scripts/analyze.py <path_to_csv>

Notes

  • Only ASCII files are supported
  • Rows with missing values are dropped entirely to ensure clean statistics
  • String columns just show a count (no further analysis needed)
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
