Most scripts are made with AutoHotKey(AHK), If you want to learn how to script, there is a scripts section ( https://www.mpgh.net/forum/forumdisplay.php?f=867 ), there you can find people's scripts with source. ATM Valve anti-cheat (VAC) doesn't see AHK as a hack because it doesn't interact with the game at all, it's only virtual keys being pressed. The best AHK "hack" Iv seen and I have been using on and off for about 2 months is ( https://www.mpgh.net/forum/showthread.php?t=1097642 ), it says it's out dated, but it still works fine, just read the steps to get it working, and if you want to see the source code just edit with notepad! Hope this helps you.
