This page is missing some information, such as explaining what is skin_folder and how to load the skins themselves.
Module Definition
The module is inherited from ItemModuleBase. So base parameters can be found there.
Module Name
The name of the module you use as the meta of the module definition is 'WeaponSkin' or 'WeaponSkinModule' if _force_search is set to true in the module definition.
(Optional) If used, it will show a description below the skin name in the inventory

String
The skin rarity. Can be one of the following : common, uncommon, rare, epic, legendary
locked
Boolean
(Optional) If set to true, it will act like the old legendary skins and won't allow the weapon modification if the skin is applied
unique_name
String
(Optional) If set to true, it will make the current weapon name the same as the skin name in the player's inventory. They cannot modify it afterwards

String

skin_folder
String
...
skin_attachments
Table
The attachments that should be added to the weapon if the skin is applied
And any value that appears in the tweak_data should merge
For Idstrings you need to write them like param="@[email protected]". Sadly there's no way to write it using a raw string. Use Bundle Modder to get the hashes.
Skin Attachments
Another optional option, you can setup attachments for your skin, working the same as most of rare/epic/legendary skins in the game.
