So for some reason on csgo, the plugin would not change the game description unless you changed the cvar ingame, which was inconvenient, so I decided to make a small fix. All it really does is request the cvar value on OnConfigsExecuted() and set it, to make sure the name you set up on gameservers_[gamemode].cfg or on server.cfg will be indeed read.
If you want to compile it yourself, obviously requires steamworks.
