How do I validate my Claude marketplace configuration?

You can use the 'claude plugin validate .' command within your project directory to check for schema compliance and common errors.

Can I test my custom plugins locally before publishing?

Yes, you can add a local marketplace path and install your plugin directly using the /plugin marketplace add and /plugin install commands.

How do I fix a 'source: Invalid input' error?

This error usually occurs when the path format is incorrect; ensure you are using the './path/to/plugin' format in your marketplace JSON.

What are the required fields for a Claude plugin?

A plugin requires a '.claude-plugin/plugin.json' file containing at least the name, description, and version of the plugin.
