What is the difference between a marketplace and a plugin?

A marketplace is a JSON catalog (marketplace.json) that indexes where plugins live, while a plugin is the actual package containing components like commands, agents, and skills.

Can I host plugins on private repositories?

Yes, Marketplace Builder supports various source types including private Git URLs, GitHub repositories, and local directory paths for internal distribution.

How do I share Claude plugins with my team?

You can add the marketplace source to your project's .claude/settings.json file. This allows team members to automatically receive prompts to install and trust the necessary plugins.

How do I ensure my marketplace.json file is correct?

You can use the 'claude plugin validate' command within your directory to check the structural integrity of your manifests and ensure they meet the required schema.
