Add the Marketplace

To install the Trail of Bits Skills marketplace, run this command in Claude Code: 
/plugin marketplace add trailofbits/skills
That’s it! The marketplace is now available in your Claude Code environment.
This adds the marketplace itself, not individual plugins. After adding the marketplace, you’ll browse and install specific plugins as needed.

​
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

​
Local Development Installation

If you’re developing plugins or testing local changes, you can add the marketplace from a local directory.
This is for plugin developers only. Most users should use the standard installation method above.

​
Prerequisites

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

​
Installation Steps

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

​
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

Ensure you’re running the command in Claude Code, not a regular terminal. The /plugin command is a Claude Code-specific command.
Try refreshing Claude Code or restarting the application. The marketplace should appear within a few seconds of adding it.
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.
