When do you read the code

While it's being generated, I'll spot check it, and after I test the code i'll peek in more detail at it. I review the code in much the same way I review code from a human dev. I almost never look closely at ALL lines. I'll do a quick look through just looking to see if anything jumps out, and then for the areas I intuitively know there might be some funny business I'll do a deeper dive into the code.
