Maker here. I created cowboy out of curiosity to make power use of Slash commands of Slack. Cowboy is extensible and has a few powerful commands right now, which you can use right away in your Slack. Look up for a movie on IMDb, or get a list of featured posts on Product Hunt -- get everything without leaving your Slack. Isn't it sounds good, huh?
