Python Data Analysis

A Python-based workflow for cleaning datasets and creating repeatable transformations and charts, using Python code to process data.

In plain words
What is it for?
Use it to handle missing values in data tables, transform data, and chart benchmark results.
Why use it?
It reduces repeated manual data cleanup and makes analysis steps easier to reproduce.

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

Python 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 2d 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

Python Data Analysis

Clean datasets and create reproducible Python transformations and charts.

Use Cases

  • Handle missing values in dataframes.
  • Create charts from benchmark results.
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.

Python Data Analysis is a skill published in the GitHub repository Raidriar7170/hermes-skilleval (124 stars, last pushed 1mo ago), licensed MIT. It adds 15 tokens to every session and 56 once invoked, about $0.0001 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.
