Could you provide an example for when it’s in use, I’ve never seen it in code before, unless it’s in a comment for documentation (i.e @param, @return)

It’s a new Luau feature called function attributes. Quoting the RFC:

Add a syntax for attributes to function declarations in the style of @name that can be placed before their declarations to adjust the behavior of the compiler, analyzer, and runtime.

Basically, if I understand correctly, putting an attribute before a function can adjust the behaviour of Luau and how it handles the function.

As far as I know, the only function attribute that exists right now is @native, which tells the compiler to compile the function to native code using native code generation
