karmabot-for-slack is a script for a chat bot built on the Hubot framework. It was initially generated by generator-hubot, and configured to be deployed on Heroku to get you up and running as quick as possible.

This script keeps track of users' positive and negative karma (clever points and stupid points) as well as an agregate score. Any users can give another user stupid or clever points, but cannot give themselves clever points.

I originally started with Donohue's karma bot, but expanded it to my own requirements.


To get this script running you should only need to copy the file into your scripts folder of your Hubot.

You will need to set the token HUBOT_KARMA_ADMIN_NAME to allow someone to clear the points. For example, my Slack username is @jacob. Therefore I would set the token to be jacob, ommiting the @:

heroku config:add HUBOT_KARMA_ADMIN_NAME=jacob


Assigning Points

To give a user clever points, simply send a message containing @user++. This will apply 1 clever point.

To give a user stupid points, simply send a message containing @user--. This will apply 1 stupid point.

After points are added, your bot will respond with a message with @user's total stupid or clever points.

Viewing the leaderboard

To see the current leaderboard for aggregate score (clever points - stupid points), send a message to your bot with the word leaderboard.

Clearing assigned points

To clear all of the assigned clever and stupid points, the specified admin user can send a message to your bot clear karma. If a user attempts this and they are not the admin user, they will be denied.

You can’t perform that action at this time.
