Cleardevelop is a mod created compatible for use in the game The Witcher.

It basically helps a player when they do game testing with improved vanilla cleardevelop console commands like unequiping all the items, skills, mutagens, skills, while retaining them for your gaming.
You can also choose to reset your character on our own only if you like it, and changes the character level, resetting the character developments and adding autoleveled version starting gears.

It does a proper cleanup for your character without resetting the level and the items back to level 1 and back to how it used to when you just started the game.
