Method 1: Add Marketplace

Add this repository as a plugin marketplace in Claude Code:

/plugin marketplace add posit-dev/skills

Then browse and install the skill categories you need through the Claude Code UI.

Method 2: Direct Installation

Install specific skill categories directly:

/plugin install open-source@posit-dev-skills
/plugin install r-lib@posit-dev-skills
/plugin install shiny@posit-dev-skills
/plugin install quarto@posit-dev-skills

   for skill in open-source/*/; do
     cp -r "$skill" ~/.config/claude-code/skills/
   done
   

Claude.ai

Skills can be uploaded to Claude.ai following the Creating Custom Skills guide.

Claude API

Use the Skills API to programmatically load and manage skills in your applications.

Using Skills

Once installed, Claude will automatically activate relevant skills based on your task. You don't need to explicitly invoke them.

For example, with the release-post skill installed:

You: Help me write a release post for dplyr 1.2.0

Claude: I'll help you create a release post. First, let me gather some information...

Claude will use the skill's knowledge to guide you through creating a properly formatted release post.

Skill Categories

This repository organizes skills into categories to make it easier to find and install skills relevant to your work:

Category	Description

We welcome contributions! Please see CONTRIBUTING.md for guidelines on creating new skills.
