It's hard to find a one size fits all because almond flour can be quite different according to who grinds it. With something like chocolate chip pecan cookies where the batter serves as a carrier for the add-ins, a finely ground somewhat airy almond flour works fine on a 1:1 ratio. I'm not sure about heavier or coarser grinds but those results are likely to vary. I buy from both Bob's Red Mill, King Arthur Flour and Trader Joe's and their almond flour is substantially different.
My advice would be to watch your batter and check as you go. If you're an experienced cookie-baker, you'll probably be able to tell if the batter is too heavy. If it is, add some leavening, maybe even an extra egg. I like the flavor of the nut flours in cookies but you may have to experiment to get the texture you want.
