How to Identify When APIs Can Be Confusioned

I've run into issues right where I wrote almost all the code. And then I went back and used something making the assumption that it did what I called it. It's not a unique problem to bigger systems or bigger teams or anything like that. This is something everybody kind of falls into. So how do you identify it? Do you just identify it when people bring stuff up like this or is there a less painful way to do that? Yes. The number of things you can use. Having static typing can definitely help a lot.
