alterlab-eda

alterlab-eda is a skill for Claude Code from AlterLab-IEU/AlterLab-Academic-Skills. It costs 258 tokens per session (3,326 once invoked), scanned A, original, MIT.

A tool for exploratory data analysis, the initial examination of a dataset to understand its structure, quality, statistics, and possible problems. It detects the file type and produces a Markdown report.

In plain words
What is it for?
Use it to inspect scientific data files, find missing or inconsistent values, generate statistical summaries, recommend visualizations, and suggest next analysis steps.
Why use it?
It gives you an initial quality check and summary before you choose methods for deeper analysis.

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

alterlab-eda 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/eda_analyzer.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.

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 88 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.
