StatsPAI_skill

StatsPAI_skill is a skill for Claude Code, Codex from brycewang-stanford/Auto-Empirical-Research-Skills. It costs 604 tokens per session (40,810 once invoked), scanned D, original, no licence file.

A guide for running a full empirical or causal analysis in Python in the style of an applied economics paper. Causal analysis studies whether one factor produces a change in another, rather than merely being associated with it.

In plain words
What is it for?
Use it for methods such as difference-in-differences, regression discontinuity, instrumental variables, synthetic control, double machine learning, or matching, including estimating equations and event-study results.
Why use it?
It helps structure the research question, statistical assumptions, tables, figures, and robustness checks needed for a complete 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 D, and why

StatsPAI_skill scanned grade D with 2 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.

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.

A mod that escalates privileges can change anything on the machine, not only the project.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

The source is not reproduced here

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.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

StatsPAI_skill is a skill published in the GitHub repository brycewang-stanford/Auto-Empirical-Research-Skills (3,759 stars, last pushed 5d ago), with no licence file. It adds 604 tokens to every session and 40,810 once invoked, about $0.0030 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
