Team Distribution

Configure automatic marketplace installation for your team by adding .claude/settings.json to your projects:

{
  "extraKnownMarketplaces": {
    "claude-bazaar": {
      "source": {
        "source": "github",
        "repo": "svgsponer/claude-bazaar"
      }
    }
  }
}

When team members trust the repository folder, Claude Code automatically installs the marketplace. See Configure team marketplaces for details.

Installing from GitHub

Once your marketplace is published to GitHub, users can install plugins with:

# Add the marketplace
/plugin marketplace add svgsponer/claude-bazaar

# Install a plugin
/plugin install plugin-name@claude-bazaar

Local Testing

Test your plugins before publishing:

# Navigate to your marketplace
cd claude-bazaar

# Start Claude Code
claude

# Add local marketplace
/plugin marketplace add .

# Install and test a plugin
/plugin install plugin-development@claude-bazaar

For iterative development:

# After making changes
/plugin-development:validate
/plugin uninstall plugin-name@claude-bazaar
/plugin install plugin-name@claude-bazaar

Uninstalling

Remove the marketplace and its plugins from Claude Code:

# Remove a specific plugin
/plugin uninstall plugin-name@claude-bazaar

# Remove the marketplace entirely
/plugin marketplace remove claude-bazaar

To completely remove, delete the cloned repository directory.

Creating Plugins Manually

If you prefer manual setup over the scaffolding commands:

1. Create Plugin Directory

mkdir -p plugins/my-plugin/.claude-plugin
mkdir -p plugins/my-plugin/commands

2. Add Plugin Manifest

Create plugins/my-plugin/.claude-plugin/plugin.json:
