作者 posit-dev · posit-dev/skills

Posit's curated Claude Skills collection — R, data-science, Quarto, and workflow skills from the people behind RStudio and Shiny.

Posit Skills is the skill pack from Posit (RStudio/Shiny). It's biased toward R and data-science workflows but covers Quarto authoring, package development, and reproducible analysis patterns. Higher quality bar than most community collections because Posit ships it as a vendor-maintained catalog.

  }
}

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

~/.cursor/mcp.json · .cursor/mcp.json
{
  "mcpServers": {
    "skills-skill-2": {

      ],
      "_inferred": true
    }
  }
}

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

VS Code → Cline → MCP Servers → Edit

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

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

Cline サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "skills-skill-2": {
      "command": "git",

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

Claude Desktop と同じ形式。Windsurf を再起動して反映。

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

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json
{
  "context_servers": {
    "skills-skill-2": {
      "command": {
        "path": "git",
        "args": [

          "~/.claude/skills/skills"
        ]
      }
    }
  }
}

context_servers に追加。保存時に Zed がホットリロード。

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

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方： skills

How to scaffold a proper R package

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

使うタイミング： You're tired of hand-writing DESCRIPTION, NAMESPACE, and roxygen2 boilerplate.

前提条件
  • Skill installed — git clone https://github.com/posit-dev/skills ~/.claude/skills/posit-skills
  • R + devtools — install.packages('devtools')
フロー
  1. Scaffold
    Use Posit R-package skill. Create a new package 'tidylaundry' with 2 exported functions: wash() and fold().✓ コピーしました
    → Directory with DESCRIPTION, NAMESPACE, R/, tests/testthat/, README
  2. Add roxygen
    Add roxygen2 docs with @param, @return, @examples for each function.✓ コピーしました
    → Inline docs that devtools::document() converts to man/
  3. Smoke test
    Write testthat tests covering happy path + one edge case each.✓ コピーしました
    → Tests passing under devtools::test()

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

注意点
  • 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

使うタイミング： You need to share analysis with stakeholders in a reproducible format.

フロー
  1. Scaffold Quarto doc
    Use Posit Quarto skill. Create a report template with YAML header, exec defaults, and Tufte theme.✓ コピーしました
    → .qmd file with chunked code + narrative
  2. Fill with analysis
    Load data/sales.csv and produce a monthly revenue chart with ggplot + a 2-paragraph insight.✓ コピーしました
    → Chunks that render to HTML/PDF
  3. Pin environment
    Capture versions with renv::snapshot().✓ コピーしました
    → renv.lock produced

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

注意点
  • 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

使うタイミング： New Shiny app, want modules + bslib theming from the start.

フロー
  1. Scaffold
    Use Posit Shiny skill. Create an app with bslib::page_fluid, 2 modules: upload + plot.✓ コピーしました
    → app.R with module files in R/
  2. Add reactive flow
    Wire upload module's reactive output into plot module's input.✓ コピーしました
    → Reactives connected; app runs

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

R package scaffolds are small token-wise; Quarto with data analysis can balloon.

セキュリティ

トラブルシューティング

よくあるエラーと対処法

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
