This is my first attempt at writing an SCP object. The idea behind it is its a hammer that makes the person holding it go crazy and try to smash all electronics with it. Any critiques would be awesome
This is not an interesting concept as it is. It does not engage me on an emotional, imaginative or intellectual level. Am I supposed to feel scared that every hammer I pick up will make me smash my phone in? Not really - items that magically force someone to do something don't really leave much human element to empathise with, or give much possibilities for subversion. Am I supposed to think "wow, I've never thought of smashing electronics with hammers before"? I mean, even those are pretty weak excuses and that's all I can think of. And you execute this in the most vanilla way possible: describe the thing, describe where it was found where it was used exactly as you'd imagine it.
Best to start with a different idea entirely, methinks, or elaborate upon this idea in a way that makes it engaging on one or more of the three levels I mentioned above.
