data-scientist

data-scientist is a skill for Claude Code, Codex from code-yeongyu/oh-my-openagent. It costs 54 tokens per session (1,339 once invoked), scanned A, original, no licence file.

A data-processing workflow that uses tools such as DuckDB, Polars, NumPy, and Matplotlib, choosing between in-memory, streaming, and remote processing.

In plain words
What is it for?
Use it to query datasets, transform data, calculate results, create charts, and run repeated Python or JavaScript analyses in persistent sessions when available.
Why use it?
It helps handle data according to its size and location, rather than forcing every task through one processing method.

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-scientist 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 today.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/ensure-js-deps.sh, scripts/ensure-py-deps.sh, scripts/quick-query.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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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-scientist is a skill published in the GitHub repository code-yeongyu/oh-my-openagent (68,699 stars, last pushed today), with no licence file. It adds 54 tokens to every session and 1,339 once invoked, about $0.0003 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.
