data-science-analysis

data-science-analysis is a skill for Claude Code, Codex from agentscope-ai/QwenPaw-Data. It costs 237 tokens per session (2,884 once invoked), scanned A, original, Apache-2.0.

A workflow for answering quantitative questions from local data files, including CSV, Excel, TSV, and scientific formats such as NPZ, FITS, and H5. It uses data-processing and scientific-computing tools to clean the data, calculate results, and check intermediate steps.

In plain words
What is it for?
Use it to inspect a local dataset, consult its data dictionary, map question terms to fields, clean and analyze the data, and produce a numeric or categorical answer.
Why use it?
It reduces mistakes caused by manually reading files or guessing which columns and categories match the question. It also provides a repeatable process for validating filters, joins, and calculations.

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-science-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 9d ago.

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

Data Science Analysis

A single, domain-agnostic workflow for answering quantitative questions from local datasets. Data files may live in any directory the task provides (e.g., input/, data/, the current working directory, or an explicit path in the prompt); first identify that data directory, then apply the workflow to it. The steps below apply to any domain (archeology, biomedical, environmental, legal, wildfire, astronomy/heliophysics/space weather, and beyond) and to any file type (tabular CSV/Excel or scientific array/binary formats like .npz, .fits, .h5). Domain-specific gotchas are flagged inline and detailed in references/domain-notes.md.

Core Principles

Principle Why
Python for all arithmetic Prevents LLM math errors
Read files directly in scripts Never hardcode numbers from manual inspection—they drift and break
Consult the data dictionary first Map every prompt term to exact columns/categories; never guess
Single consolidated script For multi-step analysis, avoid many small .py files and inline python3 -c
Print intermediate results Catches silent filtering/join errors before they reach the answer
Recompute derived metrics from raw Never trust pre-calculated rates/percentages in source files
Round only at the final step Intermediate rounding compounds error

Workflow

1. Discover & Profile

  • Identify the data directory the task provides (e.g., input/, data/, the current working directory, or an explicit path given in the prompt), then glob all files under it (e.g., <data_dir>/**/*) — data files, data dictionaries, metadata, format specs (.fmt, .text, README), helper scripts. Avoid overly restrictive filename filters that might exclude the correct data. Restrict data access to this directory.
  • Read data dictionaries / README / format specs first. Map every prompt term (e.g., "damaged", "generally unsafe", "tumor") to its exact column or category — never guess. Cross-reference discovered schemas against format specs to confirm column mappings and units.
  • Inspect raw structure before loading: read the first (and last) 10–20 rows raw (header=None) to locate the true header row, metadata/summary/footer rows, delimiters, timestamp formats, and encoding quirks (BOM → utf-8-sig).
  • For Excel, list sheet_names via pandas.ExcelFile; prioritize README/Legend/Metadata sheets, then preview each data sheet.
  • For scientific/binary files (.npz, .fits, .h5), print all keys and array shapes to identify the correct arrays before use.
  • Print exact column names and sample values; use names—not indices—for all downstream selection.

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-science-analysis is a skill published in the GitHub repository agentscope-ai/QwenPaw-Data (67 stars, last pushed yesterday), licensed Apache-2.0. It adds 237 tokens to every session and 2,884 once invoked, about $0.0012 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 2026-08-30.
