SharpSK (https://forums.skunity.com/resources/sharpsk-1-8-1-12.72/) is a Skript Addon that allows for access into other plugins APIs, such as GriefPrevention, WorldGuard, CoreProtect and more.
For example, it can be used to check if a player is the owner of a area they claimed with GriefPrevention as you can easily access it's API through SharpSK without using **cringe** methods such as using Ersatz and using events such as *on command:*, *on chat:* and such to set a variable whenever someone speaks/executes a command to check like that because as I have expressed previously that is absolutely **cringe**.
Thank you!
