Claude Marketplace

A community marketplace for Claude Code skills and agentic workflows, curated by CAIR (Center for Artificial Intelligence Research). The goal is to make reusable agent behaviors discoverable and shareable across research teams.

Set up in Claude Code

1. Register the marketplace

Add this to your ~/.claude/settings.json under extraKnownMarketplaces:

{
  "extraKnownMarketplaces": {
    "cair": {
      "source": {
        "source": "git",
        "url": "https://github.com/cair/claude-marketplace"
      }
    }
  }
}

2. Enable skills

Still in settings.json, add the skills you want under enabledPlugins. The format is skill-name@cair:

{
  "enabledPlugins": {
    "caveman@cair": true
  }
}

3. Verify

Restart Claude Code. Type / in the prompt — installed skills appear as slash commands. Skills with automatic triggers activate without a slash command when the context matches.
