If I were to make this library again....

describeCommand executor arguments

I would probably include all things related to the context of the command within one argument like this

executor(context: { adaptorContext, eventContext, keywords, rest }, ...argumentsFromParameters);

equally that could also be

executor(context: {adaptorContext, eventContext, keywords, rest }, { [parameterName]: argument });

I think currently it looks like this:

executor(adaptorContext, eventContext, keywords, ...arguments, ...rest);
