Installation

Prerequisites

• Claude Code must be installed (plugin support is in public beta)
• Git repository (for using the /cc command)

Method 1: Install from GitHub (Recommended)

1. Add the marketplace to Claude Code:

   /plugin marketplace add sourcelabs-nl/sourcelabs-claude-marketplace

2. Browse and install plugins using the interactive menu:

   /plugin

   Or install directly:

   /plugin install conventional-commits@sourcelabs
   /plugin install html-presentation@sourcelabs
   /plugin install jvm-testing@sourcelabs

3. Restart Claude Code to activate the plugin

4. Verify installation by running /help to see the new commands

Method 2: Install from Local Path

Useful for development or when working with a local clone:

1. Clone this repository to your local machine:

   git clone https://github.com/sourcelabs-nl/sourcelabs-claude-marketplace

2. Add the local marketplace to Claude Code:

   /plugin marketplace add /path/to/sourcelabs-claude-marketplace

3. Install the plugins:

   /plugin install conventional-commits@sourcelabs
   /plugin install html-presentation@sourcelabs

Method 3: Team Configuration (Automatic)

For automatic plugin installation across your team, add this configuration to your repository's .claude/settings.json:

{
  "marketplaces": [
    {
      "source": "sourcelabs-nl/sourcelabs-claude-marketplace"

  ],
  "plugins": [
    "conventional-commits@sourcelabs",
