exploratory-data-analysis

exploratory-data-analysis is a skill for Claude Code, Codex from Zaoqu-Liu/ScienceClaw. It costs 89 tokens per session (3,496 once invoked), scanned A, a copy of exploratory-data-analysis, MIT.

An exploratory data analysis toolkit for scientific files in more than 200 formats. Exploratory data analysis means checking a dataset’s structure, quality, statistics, and useful next analyses before deeper work.

In plain words
What is it for?
Use it to identify file types, summarize metadata and distributions, assess data quality, and generate reports and visualization suggestions.
Why use it?
It helps you understand unfamiliar scientific data and find quality or completeness problems before choosing an analysis method.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/eda_analyzer.py <filepath> [output.md].

Good fit Use it to identify file types, summarize metadata and distributions, assess data quality, and generate reports and visualization suggestions.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

exploratory-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 7d 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.

Exploratory Data Analysis

Overview

Perform comprehensive exploratory data analysis (EDA) on scientific data files across multiple domains. This skill provides automated file type detection, format-specific analysis, data quality assessment, and generates detailed markdown reports suitable for documentation and downstream analysis planning.

Key Capabilities:

  • Automatic detection and analysis of 200+ scientific file formats
  • Comprehensive format-specific metadata extraction
  • Data quality and integrity assessment
  • Statistical summaries and distributions
  • Visualization recommendations
  • Downstream analysis suggestions
  • Markdown report generation

When to Use This Skill

Use this skill when:

  • User provides a path to a scientific data file for analysis
  • User asks to "explore", "analyze", or "summarize" a data file
  • User wants to understand the structure and content of scientific data
  • User needs a comprehensive report of a dataset before analysis
  • User wants to assess data quality or completeness
  • User asks what type of analysis is appropriate for a file

Supported File Categories

The skill has comprehensive coverage of scientific file formats organized into six major categories:

1. Chemistry and Molecular Formats (60+ extensions)

Structure files, computational chemistry outputs, molecular dynamics trajectories, and chemical databases.

File types include: .pdb, .cif, .mol, .mol2, .sdf, .xyz, .smi, .gro, .log, .fchk, .cube, .dcd, .xtc, .trr, .prmtop, .psf, and more.

Reference file: references/chemistry_molecular_formats.md

2. Bioinformatics and Genomics Formats (50+ extensions)
