The metric is: I run the code and it works?

I've read other people's code for 25 years for a living. I'm pretty good at it.

So when I get a piece of code or an algorithm, I can read it check if it looks like something I'd allow in a pull review.

We also have this thing called "unit tests", which are pretty good at detecting erroneus code. Some people even write them first and then adjust their code to match.
