It all depends, not a set cut and dry outline. It's a great time to add muscle and bodyfat. You can't go overboard like a lot of people think, "ah I'm prime for muscle so I can eat a huge surplus!" Yes, a day or two would be fine but you have to remember the body does what it needs to SURVIVE, not have boat loads of muscle with low bodyfat. You were restricting calories, the body doesn't like that so your metabolism slows. Of you're feeding it a ton of calories after a long deprivation, it's going to try and store a lot of those calories. Both as muscle and fat.
You're usually more sensitive to insulin so adding more carbs than normal is great for a few weeks but they still need to be quality carbs. You could probably bump carbs to 40-50% of calories for a few weeks but still stay at a modest surplus (250-500cals)
Easiest way to ruin your hard work is to eat too many cals post cut thinking you're gonna get huge. I ate more carbs than normal for about 4 weeks post show and feel like I added good mass & some fat. Now I'm doing a recomp for about another 4-5weeks, after this ill slowly add carbs back in for a solid lean bulk for 12 weeks or so. Hope that helps.
