Let me see if a similar example will help. Rather than AHK as most people don't know what that is, me included, other than AutoHotKey scripts, let use Python since it's a scripting language also. Which would be pretty similar to what you are asking about. Running code to get information from the game in that language and then process commands.
None of that is allowed. You cannot make c#, c++, python, json, or java applications and have anything access anything about the game while it is running to know if a friend is online for example. You also cannot write files in any format to disk such as csv or json.
No external code has access to the game and data sent to and from the server in any way.
What you want to do is not possible.
All disk read and write, specifying file names or locations is all disabled.
The Lua code available only works while in game. No tapping into anything to share with discord or a web browser.
All you can do is use the provided Lua format for saved variables. Such as a name of a player and settings for a mod to toggle a feature on and off. It only saves when you logout or reload the ui.
While you could make a program to read the Lua saved variables, you cannot share anything in real time. Should you find a way that will be rectified.
