1. Your class can be no longer than 100 lines of code.
2. Your methods can be no longer than five lines of code.
3. You can pass no more than four parameters and you can’t just make it one big hash.
4. When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done.

You can break these rules if you can talk your pair into agreeing with you.
