You should document the API, I only found this page with broken javadocs: https://dev.bukkit.org/projects/silkspawners/pages/api

Will do 👍

Can you please post some code snippets of your plugin, where you call the SilkSpawners API? I'm missing a reproducible example.

Thanks!
Make sure to add depend: [SilkSpawners] to your plugin.yml and move the initialization of SilkUtil into your onEnable() method - otherwise SilkSpawners is not yet correctly initialized.

private SilkUtil su;

@Override
public void onEnable() {
  // do your stuff
  su = SilkUtil.hookIntoSilkSpanwers();
  ...
}

I'll add a warning nevertheless.
