A free mod for The Sims 4, by FakePikachu.

This mod will randomize all the skills for the NPCs with random traits. It’s designed for those of you who don’t want to play with the same NPC over and over again. The randomization is completely automated and the only thing you have to do is install the mod.

This mod is the perfect solution for those of you who want to play with a different NPC every time you start a new game. It’s designed to work with all the existing games, but if you don’t have the newest version of the game, then you won’t be able to use this mod.
