There are several instances of ambiguous writing in this article, which would get the scientist writing it in trouble.

Examples:

SCP??-XXXX-1 may also be used temporarily under beneficial circumstances or with permission from a researcher with level 4 clearance to exterminate or contain colonies that pose a threat to civilians.

What are 'beneficial circumstances'? The overall structure of this sentence is also confusing. Does it mean that you can use SCP-XXXX-1 to eliminate SCP-XXXX-1? You make that clear later in the article, but right now it's confusing.

SCPXXXX-1, when it is not being used, is to be bred in a 4m, cubic steel cell, filled with 200 litres of soil, and supplied bi-weekly with 70kg of human organic matter.

Is the cell 4m by 4m by 4m, or 4 cubic meters? Because 4 cubic meters can hold 4000 liters, and a 4m by 4m by 4m cell can hold 64000 liters, so your 200 liters of soil won't be very much.

with 3 fingers and toes.

On each hand/foot?

When a colony of SCPXXXX comes into contact with organic matter of human origin, all SCPXXXX instances will proceed to cut up parts of it into pieces of about 2,6 cm.

Does 'organic matter of human origin' include blood, feces, or urine? What about bones?

it will also target live humans in large quantities,

Large quantities of humans, or of SCP-XXXX?

This is looked down upon by a select group of researchers who believe that the potential risks of this project are higher than its efficiency.

This would *really* get the writer of this article in trouble. Badmouthing a 'select group of researchers' is probably the fastest way to get in trouble at an academic institution. I've tried it in real life and it really sucks!

Similarly, the speculation that "China seems to be the most likely place of origin" is presented without any justification whatsoever.

The large paragraphs just kind of run on and are hard to read. Shorter, more varied paragraphs would be better, especially if each paragraph led naturally to the next. Look at SCP-4999. It has beautiful paragraph structure, some with only one sentence, others much larger, many paragraphs picking up where the last one left off.

The tools being bone or wood makes it sound primitive, but creating gas canisters is extremely advanced. That implies that they have ways of creating solid, leak-proof containers and getting gas in them without any spilling out on them in the mean time. That requires more than bone spears and wood axles and pulleys.

Also, I was interested in finding out more about these guys, but it seems like they're just little, aggressive people. That's interesting, but I feel like they could use one more interesting facet. What's something else they do besides reproduce through harvesting flesh and fighting?

The very specific way of recapturing doesn't really speak to me. You have extremely specific things here that don't 'pay off' later. Are they sensitive to noise? Does the chloroform kill them or incapacitate them? Why not other kinds of gas? Why not other levels of sound? Why mercaptan gas?

Unless it's extremely important to use those exact steps in that exact order with those exact ingredients, it would be better to be more general in what can be done. You don't want these guys breaking out because the agents didn't bring chloroform and have no idea what to do now that one step in the very specific sequence is broken. Maybe something like "Chemical weapons such as tear gas and chloroform have proven effective in controlling nests of SCP-XXXX, as have loud noises (110 db or higher recommended). Something like that.
