I noticed that your description does not actually contain a description of the creature.
;) Im working on it as we speak.
I did some details
The Special Containment Procedure feels more like "Casual Discussion" than "Records Keeping" vernacular. That being said it's interesting. I personally would like to see a sinister undertone to it HOWEVER that's completely unnecessary as the SCP Foundation is only about Securing, Containing, and Protecting the public from various anomalous entities that may drastically alter or affect our current way of life. Therefore a gargoyle that can teleport (be it autonomous or otherwise) would have a relatively major affect on our way of life and is certainly something the foundation would at least investigate if not contain completely. I like it. I'd like it to have a little more body but it's cool nonetheless.
Going to clear up some misconceptions here.

This is somewhat misleading. The general approach is that the Foundation's mission is to contain all anomalies, regardless of how much they would alter/affect the human way of life, because the Foundation exists to prevent humanity from finding out the anomalous exists at all. As such, there are plenty of relatively mundane things in simple storage, such as the things listed in the log of anomalous items.

Edmund Fitzgerald, this is vague advice. What do you mean by "a little more body"? What kind of material should the author add? Why would such material improve the article, as opposed to just cause bloat?
Right now it's fine but a little skeletal. It needs more. Not in any particular area just more. He's got an SCP. He's got a story and containment protocol. He just needs to expand it. As far as improve v. bloat the SCP that's a matter of execution in my opinion.
First of all, you should give this a re-read, there's quite a few capitalization and spelling errors.
Second: you wrote a creepy ghost story with a creepy monster.
