What kind of Mod is this?

http://www.modthesims.info/download.php?t=476620 - Its a mod to give the Sims with the Insane trait the ability to talk to appliances like the robots do.

I'm just wondering if its a core mod or a lighter mod. I'm not sure if I'll use it if its a core mod.

The mod is listed under the "Pure Scripting Mods" category, and is indeed a pure scripting mod.

Core-Mods are usually pretty easy to spot, since they need to have relatively large file-sizes to contain the entire Core file they are replacing.

For instance both [ErrorTrap] and [UntranslatedKey] (the two Core-Mods I maintain) are both over 300kb in size.
