클라이언트 선택

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "skills-skill-2": {
      "command": "git",
      "args": [
        "clone",

        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "skills-skill-2": {
      "command": "git",
      "args": [

        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "skills-skill-2": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/posit-dev/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "skills-skill-2": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/posit-dev/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "skills-skill-2",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/posit-dev/skills",
        "~/.claude/skills/skills"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "skills-skill-2": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/posit-dev/skills",
          "~/.claude/skills/skills"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add skills-skill-2 -- git clone https://github.com/posit-dev/skills ~/.claude/skills/skills

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

사용 사례

실전 활용법: skills

How to scaffold a proper R package

👤 R developers starting a new package and wanting usethis/devtools conventions ⏱ ~30 min intermediate

언제 쓸까: You're tired of hand-writing DESCRIPTION, NAMESPACE, and roxygen2 boilerplate.

사전 조건

Skill installed — git clone https://github.com/posit-dev/skills ~/.claude/skills/posit-skills
R + devtools — install.packages('devtools')

흐름

Scaffold

Use Posit R-package skill. Create a new package 'tidylaundry' with 2 exported functions: wash() and fold().✓ 복사됨

→ Directory with DESCRIPTION, NAMESPACE, R/, tests/testthat/, README
Add roxygen

Add roxygen2 docs with @param, @return, @examples for each function.✓ 복사됨

→ Inline docs that devtools::document() converts to man/
Smoke test

Write testthat tests covering happy path + one edge case each.✓ 복사됨

→ Tests passing under devtools::test()

결과: A package that passes R CMD check on day one.

함정

Generated code uses base R where tidyverse would be clearer (or vice versa) — State the style preference upfront

Author a reproducible Quarto report

👤 Analysts publishing reports with code + narrative ⏱ ~45 min intermediate

언제 쓸까: You need to share analysis with stakeholders in a reproducible format.

흐름

Scaffold Quarto doc

Use Posit Quarto skill. Create a report template with YAML header, exec defaults, and Tufte theme.✓ 복사됨

→ .qmd file with chunked code + narrative
Fill with analysis

Load data/sales.csv and produce a monthly revenue chart with ggplot + a 2-paragraph insight.✓ 복사됨

→ Chunks that render to HTML/PDF
Pin environment

Capture versions with renv::snapshot().✓ 복사됨

→ renv.lock produced

결과: A reproducible report anyone can re-render given the data.

함정

Quarto render fails silently on missing system deps — Check quarto check output; common issue is missing tinytex or chromium for PDF

Scaffold a Shiny app with modern patterns

👤 R developers building internal apps ⏱ ~40 min intermediate

언제 쓸까: New Shiny app, want modules + bslib theming from the start.

흐름

Scaffold

Use Posit Shiny skill. Create an app with bslib::page_fluid, 2 modules: upload + plot.✓ 복사됨

→ app.R with module files in R/
Add reactive flow

Wire upload module's reactive output into plot module's input.✓ 복사됨

→ Reactives connected; app runs

결과: A modular Shiny app that's easy to extend.

skills-skill-2 + claude-code-skill-factory-skill

Use Posit skills as reference patterns when authoring new skills

Show me the structure of a Posit skill, then /build a parallel skill for Julia package dev.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출
R package scaffolding	-	New package
Quarto authoring	-	Reports and docs
Shiny patterns	-	Internal app dev
Reproducibility (renv)	-	Pinning environment

비용 및 제한

운영 비용

API 쿼터: None
호출당 토큰: Varies per skill
금액: Free
팁: R package scaffolds are small token-wise; Quarto with data analysis can balloon.

보안

권한, 시크릿, 파급범위

자격 증명 저장: No credentials

데이터 외부 송신: None by default

문제 해결

자주 발생하는 오류와 해결

Generated R code uses outdated tidyverse APIs

State target package versions: 'dplyr 1.1+, tidyselect 1.2+'

Skill not triggered on R contexts

Claude auto-triggers on file extensions; explicitly invoke 'Use Posit R skills ...' to guarantee

대안

skills 다른 것과 비교

대안	언제 쓰나	단점/장점
Hand-written with usethis	You already know the conventions cold	More control, slower setup
