The concept:
Elevator Pitch: The SCP seems to be a small void/black hole type thing, that deletes any matter that makes contact with it.
Overall this is very vague. The only thing in pitch are the effects, there doesn't seem to be anything that hints at the skips origins/purpose or the Foundations interactions with it. To add on, the anomaly doesn't really feel like much an anomaly. Considering blackholes already do that sort of thing irl, I'm unsure of what makes the skip unique and/or attention grabbing, as the effect isn't really 'anomalous' per se. In general, the skips effects feel way to op, the skip pretty much causes the end of the world, with nothing that can really counteract it. Overall, this feels a little bit lazy, as it just makes the skip dangerous for the sake of being dangerous, there doesn’t seem to be a reason behind it.
Comrade Waldo has pointed out most of my other concerns with the concept. As the language choice doesn't support a clinical tone, and the all round lack of info on both the skip and narrative cause this to more or less become a "thing that does a thing".

The narrative:
Central Narrative: At the end of the article it cuts off in the middle of an addendum and switches to a small story, told from first person, about how this anomaly caused the end of the world. and how the character dies at the end.
This isn't really a story, there doesn't seem to be any first, second or third act here. All thats really explained is the the "story" ends abruptly, and then a short first person story starts. There doesn't seem to any progression of events here, and as a result I'm left confused on why/how all of this is happening. I would highly recommend you go into more detail about the narrative, as currently, there really isn't much here to critique or keep my interest for that matter.
Red or green?
Due to my afore mentioned concerns, no Greenlight. -The concept is too vague for me to really become invested/interested. Overall, I would recommend you give the story more detail, try to think about what you want to the feel and how will achieve that. As for the concept, I would recommend you explain more about the effects themselves, look into why the skip is here and what the Foundations initial reactions to it are.
If you would like me to give this further advice/feedback, then feel welcome to shoot me a PM or ask via IRC. response times generally range from 2-12 hours over PMs. If your looking for additional critiques in general, then I couldn't recommend the Butterfly squad more:)
