Does an "after you attack" effect resolve before or after the counterattack?

Question

Accepted Answer

After. "After an attack" waits until the whole attack, counterattack included, has resolved, while "after performing an attack test" and after-test effects come before it. That is why a card that hides you right after the test can avoid the counterattack, but a post-attack move cannot.
