# Installation

> Add the Trail of Bits Skills marketplace to Claude Code

## Add the Marketplace

To install the Trail of Bits Skills marketplace, run this command in Claude Code:

```bash theme={null}
/plugin marketplace add trailofbits/skills
```

That's it! The marketplace is now available in your Claude Code environment.

<Note>
  This adds the marketplace itself, not individual plugins. After adding the marketplace, you'll browse and install specific plugins as needed.
</Note>

## What Happens Next?

Once you've added the marketplace:

1. **Browse available plugins** - Use `/plugin menu` to see all 35 available plugins
2. **Install plugins** - Select and install plugins that match your workflow
3. **Start using skills** - Invoke skills, commands, and agents from installed plugins

<Steps>
  <Step title="Verify Installation">
    Run `/plugin menu` to confirm the marketplace was added successfully. You should see plugins from Trail of Bits available for installation.
  </Step>

  <Step title="Choose Your First Plugin">
    Browse the available plugins and select one that matches your current needs. See the [Quick Start guide](/quickstart) for recommendations.
  </Step>

  <Step title="Install and Use">
    Install your chosen plugin and start using its skills, commands, and agents immediately.
  </Step>
</Steps>

## Local Development Installation

If you're developing plugins or testing local changes, you can add the marketplace from a local directory.

<Warning>
  This is for plugin developers only. Most users should use the standard installation method above.
</Warning>

### Prerequisites

* Clone the Trail of Bits Skills repository
* Navigate to the **parent directory** of the repository

### Installation Steps

```bash theme={null}
# Navigate to the parent directory
cd /path/to/parent  # e.g., if repo is at ~/projects/skills, be in ~/projects

# Add the local marketplace
/plugins marketplace add ./skills
```

<Note>
  Note the different command: `/plugins` (plural) is used for local development, while `/plugin` (singular) is used for remote marketplaces.
</Note>

## System Requirements

Trail of Bits Skills marketplace works with:

* **Claude Code** - Any recent version
* **Operating Systems** - Linux, macOS, Windows
* **No additional dependencies** - Individual plugins may require specific tools (noted in their documentation)

## Troubleshooting

<AccordionGroup>
  <Accordion title="Command not recognized">
    Ensure you're running the command in Claude Code, not a regular terminal. The `/plugin` command is a Claude Code-specific command.
  </Accordion>

  <Accordion title="Marketplace not appearing in menu">
    Try refreshing Claude Code or restarting the application. The marketplace should appear within a few seconds of adding it.
  </Accordion>

  <Accordion title="Cannot find specific plugin">
    Make sure you've added the marketplace first using `/plugin marketplace add trailofbits/skills`. Individual plugins won't be visible until the marketplace is added.
