At a glance
Modern R development practices emphasizing tidyverse patterns (dplyr 1.1 and later, native pipe, joinby, .by grouping), rlang metaprogramming, performance optimization, and package development.

- Claude needs to write R code
- SKILL.md covers Core Principles, Modern Tidyverse Essentials, rlang Metaprogramming and Performance Optimization, plus 3 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
R Development is an agent skill from aiskillstore/marketplace. Modern R development practices emphasizing tidyverse patterns (dplyr 1.1 and later, native pipe, joinby, .by grouping), rlang metaprogramming, performance optimization, and package development. Use when Claude needs to write R code, create R packages, optimize R performance, or provide R programming guidance.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/object-systems.md`, `references/package-development.md` and `references/performance.md`).
It sits in Development, covering Performance optimization. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Claude needs to write R code
- Create R packages
- Optimize R performance
- Provide R programming guidance
Example prompts
- “/r-development”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Use modern tidyverse patterns - Prioritize dplyr 1.1+ features, native pipe, and current APIs
- Profile before optimizing - Use profvis and bench to identify real bottlenecks
- Write readable code first - Optimize only when necessary and after profiling
- Follow tidyverse style guide - Consistent naming, spacing, and structure
What it can do on your machine
Read from SKILL.md and the folder at commit 755bc35. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are r).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
R Development loads about 1.6k tokens when it runs, and up to ~9.1k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 352 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 352 words (~1,556 tokens).
“This skill provides comprehensive guidance for modern R development, emphasizing current best practices with tidyverse, performance optimization, and professional package development.”

R Development is an agent skill from aiskillstore/marketplace.by grouping), rlang metaprogramming, performance optimization, and package development.
When should I use R Development?
R Development fits situations like: Claude needs to write R code; create R packages; optimize R performance; provide R programming guidance.
How do I install R Development in Claude Code?
Run `npx skills add aiskillstore/marketplace --skill r-development -a claude-code`. Or copy the skill folder (skills/codingkaiser/r-development in aiskillstore/marketplace) into .claude/skills/r-development in your project. Claude Code loads it when a task matches its description.
How do I install R Development in Codex?
Run `npx skills add aiskillstore/marketplace --skill r-development -a codex`. Or copy the skill folder (skills/codingkaiser/r-development in aiskillstore/marketplace) into .agents/skills/r-development in your project. Codex loads it when a task matches its description.
Can I use R Development in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill r-development -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/r-development, .gemini/skills/r-development, .github/skills/r-development and .opencode/skills/r-development in your project.
What does R Development need to run?
SKILL.md names no scripts, command-line tools or credentials: R Development is instructions for the agent only.
Does R Development access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is R Development safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does R Development use?
No licence was found for R Development or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does R Development use?
About 1.6k tokens (SKILL.md is roughly 6.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 7.6k tokens, read only when the agent opens those files.
