What is r-skills marketplace?

A set of tools for writing R code, including support for tidyverse data work, statistics, Bayesian analysis, performance, testing, and code intelligence. R is a programming language commonly used for data analysis.

Use it to develop R data-analysis and statistics code, work with tidyverse or rlang, build Bayesian models, improve performance, write tests, and find definitions or references in code.

It helps an agent understand R projects and catch or navigate code issues while you work. It brings several R development practices into one add-on.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/ab604/claude-code-r-skills

Made for: Claude Code.

Security

Grade A, and why

r-skills marketplace 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 1mo 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 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.
