SCP-XXX is too be kept…
is to be kept…
If SCP-XXX shows good behavior SCP-XXX requests for certain objects could be considered.
Comma after behavior. Also, it should be "SCP-XXX's requests", and I feel that "may" would work better than "could".
SPC-XXX's Clinical depression should be treated by an on-site child Psychiatrist .
Unnecessary space before the period, and neither Clinical nor Psychiatrist should be capitalized.
Requests to visit relatives are under consideration, but ill advised.
"ill-advised." Also, why exactly?
Is a teenager with the ability to spontaneously convert matter into into crystalline form.
should be "SCP-XXX is a teenager…" Also you have into twice.
SCP-XXX claims to not have control over it's anomalous abilities.
"It's" refers to it is, you "its".
SCP-XXX effects all forms of matter except for minerals displaying a Hardness of 9 on the Mohs Hardness Scale .
You have an unnecessary space after the period.
Analysis of the Crystals created by SCP-XXX show that they match the molecular make up of the previous save for the molecular structure that it now exhibits.
Should Crystals be capitalized? Also, I'm not entirely sure what this sentence is saying.
The crystals now referred to as SCP-XXX-1 have no anomalous properties themselves.
should have commas after "crystals" and 1.
SCP-XXX's Secondary effects include a condition similar to frostbite appearing on SCP-XXX's Skin , however this has been treated accordingly.
I don't believe secondary or skin should be capitalized here.
SCP-XXX had been recovered in a warehouse at [Redacted] ,Legal papers state that SCP-XXX was to be sold to Jewel manufac(turererereer) Not sure how to spell that, however SCP-XXX claims that a Step Father named █████ had forced SCP-XXX to generate samples of SCP-XXX-1.
Unnecessary space after [REDACTED] and the comma before Legal should be a period. Jewel shouldn't be capitalized unless its a company name. Also, its jewel manufacturer(s), depending on if its plural or singular.
Further Investigation has led to the conclusion that the the aforementioned Step father had been selling samples SCP-XXX-1 to various pawn shops and stores.
Unnecessary capitalization on investigation, "the" used twice, stepfather is one word and shouldn't be capitalized. "selling samples of SCP-XXX-1…"
