The official annotation used to import syntax to the docs.

To add this to your addon, you have to copy the SKU class into your plugin and change the package to one of your own.

These annotations work best with syntax loaded staticly with Skript's native registration system. Here is an example:

@SKU.data(
        name = "Name of the Element",
        desc = "Description of the element.",
        example = "An example "
)
public class SampleEffect extends Effect {

    static {
        Skript.registerEffect(SampleEffect.class, "[syn]tax");
    }
