class Foo {

  @on('axon__task.completed',  {   
    environment: 'development',   
  })
  static check(...params, runtime) {
    const {
      weight, 
      source,   // "script" or "event" 
      metadata,
      event,   
      context   // the event document, when fired by a user event.
    } = runtime

    console.log('checking')
  }
