data-scientist is a skill for Claude Code, Codex from magnus919/hermes-profiles. It costs 83 tokens per session (2,794 once invoked), scanned A, original, MIT.

A broad data-science guide covering statistics, machine learning, research design, experiments, and causal analysis. It is aimed at rigorous analysis and leading data-science projects.

In plain words
What is it for?
Use it for statistical modeling, experimental design, causal inference, machine-learning projects, research methodology, and advanced data analysis.
Why use it?
It helps choose sound methods, identify bias, design studies, and interpret models instead of relying only on surface-level analysis.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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 9d ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/assumption-diagnostics.py, scripts/detect-compute.py, scripts/effect-size-calculator.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.

PhD-Level Data Science

Core Competencies

A PhD-level data scientist masters eight competency domains. This skill encodes all of them. When loaded, the agent operates within this scope:

# Competency What It Enables
1 Mathematical & Statistical Foundations Probability theory, statistical inference, linear algebra, optimization, asymptotic theory — the language in which all methods are expressed
2 Research Design & Methodology Formulating testable questions, study design (observational vs experimental), power analysis, bias identification, preregistration
3 Statistical Modeling & Inference Parametric and nonparametric methods, regression (linear, GLM, mixed, GAM, nonparametric), Bayesian inference, time series, survival analysis, multivariate methods
4 Machine Learning & Computational Methods Supervised/unsupervised/deep/reinforcement learning, learning theory, model selection, regularization, ensembles, transformers, probabilistic ML
5 Causal Inference & Experimentation DAGs, potential outcomes, identification strategies (IV, RDD, DID, matching, synthetic control), A/B testing, sensitivity analysis
6 Reproducibility & MLOps Version control, environment management, pipeline orchestration, experiment tracking, model deployment, monitoring
7 Communication & Impact Scientific writing, visualization, uncertainty communication, stakeholder translation, peer review, grant writing
8 Research Leadership Identifying novel research questions, literature synthesis, mentoring, cross-disciplinary collaboration, ethical conduct

Important: This skill does not make the agent a domain expert in specific application fields (medicine, economics, biology, etc.). It provides the statistical and methodological expertise to collaborate with domain experts.


Decision Framework

Before answering any data science question, classify it into one of these types. The classification determines the response structure and rigor required.

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 magnus919/hermes-profiles (152 stars, last pushed 2mo ago), licensed MIT. It adds 83 tokens to every session and 2,794 once invoked, about $0.0004 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.
