Community-curated plugins for Claude Code — 9 slash commands and 5 hooks for developer workflows.

Installation

1. Clone the marketplace

git clone https://github.com/jannik-cas/claude-code-toolkit.git \
  ~/.claude/plugins/marketplaces/claude-code-toolkit

2. Register the marketplace

Add the following entry to ~/.claude/plugins/known_marketplaces.json:

{
  "claude-code-toolkit": {
    "source": {
      "source": "github",
      "repo": "jannik-cas/claude-code-toolkit"
    },
    "installLocation": "<HOME>/.claude/plugins/marketplaces/claude-code-toolkit",
    "lastUpdated": "2026-03-08T00:00:00.000Z"
  }
}

Replace <HOME> with your actual home directory path (e.g., /Users/yourname).

If the file already has entries (like claude-plugins-official), add claude-code-toolkit as a sibling key inside the existing JSON object.

3. Enable plugins

Add the plugins you want to ~/.claude/settings.json:

{
  "enabledPlugins": {
    "changelog@claude-code-toolkit": true,
    "explain@claude-code-toolkit": true,
    "security-scan@claude-code-toolkit": true
  }
}

Or enable all 14 at once:

{
  "enabledPlugins": {
    "changelog@claude-code-toolkit": true,
    "explain@claude-code-toolkit": true,
    "test-fix@claude-code-toolkit": true,
