module.exports = (robot) ->
  robot.hear /(.*(@here|@channel).*)/i, (msg) ->
    alerted_content = msg.match[1]
    if alerted_content.length < 20
      msg.reply "Please don't be lazy when using here or channel!\n When using here or channel commands,
everyone gets alerted and has to decide if they should go look at the problem in slack.
If you don't put enough information in the *same line* as the
channel or here, you're forcing people to go back to slack to find
out what's going on instead of letting them decide more quicly via the
information in the alert.  This is selfish behavior, you're trading a
few seconds of your own time for a much greater amount of everyone 
else's time. Unfortunately re-editing your last message to include the 
here or channel command will not trigger the notification.\n
