Foodcritic is a lint tool for your Chef cookbooks that you can use to find common problems.
In this talk I will show how you can extend Foodcritic with custom rules that you write yourself. We'll look at how Foodcritic actually works, the api available to write rules with and how you can test that your rules work properly.
Andrew's slides are available on slideshare.
Andrew (@acrmp) loves Chef and is the original author of the Foodcritic and ChefSpec tools.
