JUMP [ACTION]
With the Jump Action, you attempt to leap more
than 5 feet (a jump of 5 feet or less is treated as
Difficult Terrain). When you take this Action,
your Speed must be greater than 0, and you must
make a DC 10 Strength Check (Acrobatics or
Athletics). If you don’t Move at least 10 feet
immediately before this Action, you have
Disadvantage on the check.
On a failed check, you leap 5 feet horizontally
or vertically.
On a successful check, the check’s total
determines the distance in feet that you can clear
horizontally, or half that total if you’re jumping
vertically (round down). This jump doesn’t
expend your movement, but the distance you
clear can’t exceed your Speed.

Please, please, please.
Merge Acrobatics and Athletics into a single "mobility" skill called Athletics.
Climbing includes balancing. Jumping includes falling.
Athletics can sometimes apply to a Strength check and sometimes a Dexterity check − but it is the same skill.
(The abilities themselves are problematic. The Athletics skill is a single skill.)
