 Your plugin's rule name must be namespaced, e.g. `your-namespace/your-rule-name`, to ensure it never clashes with the built-in rules. If your plugin provides only a single rule or you can't think of a good namespace, you can use `plugin/my-rule`. _You should document your plugin's rule name (and namespace) because users need to use them in their config._
