CoreScript

A CoreScript is a Lua script with level 4 security context (what functions they have access to) that does several "core" functions. They are currently only found within the ScriptContext and CoreGui services.

An example of a "core function" is the "core GUI", the GUI at the top of your screen. The scripts run the backpack, escape menu, built in-plugins such as the Avatar Importer, purchase prompts, and localization.

Some functions used in a CoreScript are when you record, as CoreGui:ToggleRecording is called. Another example is when you take a screenshot, as CoreGui:TakeScreenshot is called.
