open-scholar-skill: Skill for Claude Code

.claude/skills/scholar-replication/SKILL.md

scholar-replication is a skill for Claude Code from joshzyj/open-scholar-skill. It costs 209 tokens per session (20,024 once invoked), scanned C, original, no licence file.

A toolkit for preparing a journal-ready replication package: the scripts, data, instructions, and tests needed for other researchers to reproduce a social science study.

In plain words
What is it for?
Use it to assemble a structured replication folder, create a README, test research code, and validate the package before submission.
Why use it?
It removes the effort of organizing research files and writing the documentation needed to check whether published results can be reproduced.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter.

This is joshzyj/open-scholar-skill's own configuration. It tells Claude Code how to work on open-scholar-skill itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything open-scholar-skill configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is Rscript -e "renv::restore()" 2>&1 | tee ../renv-restore-log.txt.

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 C, and why

scholar-replication scanned grade C 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 8d 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.

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.

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.

scholar-replication is a skill published in the GitHub repository joshzyj/open-scholar-skill (141 stars, last pushed today), with no licence file. It adds 209 tokens to every session and 20,024 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it C with 2 findings (recursive force delete, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
