Skacket is a Skript addon that adds user-friendly syntax for many common things you might want to do with packets, such as showing block breaking animations, prompting the user with a sign GUI, etc. This addon gives the user less control than ThatPacketAddon (it doesn't support every single packet type, only a select few with limited syntax), so I think it's a fine addition to Minehut's plugin library without introducing any security issues.
