I believe this can be done by deleting the message that started the command, like
if (message.deletable) {
message.delete();
}
But to only do this on a particular command, we would need the command handler to receive the message parameter.
Oh awesome 馃憤 . Thanks for the example 馃
I've tested the delete method, and in order for the bot to execute it it needs the "Manage Messages" permission:

or this error occurs:

I think our server has the bots role so maybe we could add the permission there or create a new role with it.
As for the message parameter on the command handlers, what do you guys think @garretcharp @eddiejaoude ? If we have it, this code that deletes the message would be only on the commands that want that. Also, we could have access to more information when creating the embed like adding message.author.username
Sounds good. Having access to the username would be good to include in the bot's response. Could pass it as a 3rd parameter?
Good spot on the bots role, I have now added that permission to that role 馃憤
