Need lua help (Involving addons)

I was wondering how to detect if a server has a certain addon using a lua command.

If the addon has any custon ConVars on the client, you can check if they are present using console. Otherwise, unless the server allows you to run clientside Lua, there’s no way other than inspection.

If the server has client side lua enabled, what code would i use to detect it?

If the addon creates any global variables or hooks clientside, you can check if those exist.

alright thanks!
