    Usage: ruby #{File.basename(__FILE__)} <marketplace-root>...

    Each <marketplace-root> is a repo root containing
    .claude-plugin/marketplace.json. Every plugin declared in that
    marketplace is validated with the plugin_config `validate` operation,
    against that marketplace's manifest.

    Documented default invocation for this machine:
      ruby #{__FILE__} #{DEFAULT_MARKETPLACE_ROOTS.join(' ')}
