With regards to writing an SCP, however, I look at it this way:
First, the Special Containment Procedures are, in my opinion, a genius idea, especially placed in the front of the article. They force the reader to interact with the SCP before they ever know what it is they're dealing with. There are plenty of ways to use this. For example:
Special Containment Procedures: All known instances of SCP-2941 are to be kept within separate and fully-isolated bio-containment chambers within Site-103. Instances should be provided with four to six hours of direct light from an overhead fluorescent. Each instance of SCP-2941 must be checked at least four times a day to confirm that specimen morale levels fall within mandated guidelines (for more information see Document 2941-M-5). Any measurements of specimen morale levels falling above standard containment parameters should be reported immediately to the current project head. Should standard demoralization acts prove insufficient, please consult Document 2941-DM-1 for Stage B countermeasures.
Since Incident 2941-3-2, interaction with SCP-2941 is limited to researchers with Level 3 clearance. Additionally, transport of SCP-2941 instances to and from other Site-103 research wings must be carried out in pre-approved routes free of Foundation personnel traffic.
So, now you know it's something that you have to measure the morale of, keep them demoralized, and that there's a risk of breach if they meet people.
You still have no idea it's a bunch of ambulatory fruit.
Remember that in the Containment Procedures, you have to talk about how to contain the anomaly, but you do not talk about what the anomaly is. I've written a number of zingers based on this very fact:
Any lack of appetite or difficulty swallowing observed in any organisms within containment must be immediately brought to the attention of Site-66's veterinarian surgeon, who will assess whether emergency ocular removal is necessary.
In the event of a collision, the mass, density, and Schwarzschild radius of SCP-2460 must be remeasured and its resulting new orbital trajectory calculated.
Furthermore, if they show signs of decreased morale, they are to be reminded that they will remain in place until the traffic clears.
I love the Containment Procedures.
The next thing you have to remember is that the Description describes what the anomaly is, and that's it. Specifically, you don't have to talk about what it means.
SCP-2203 does what it says on the tin. It tells you who your best match is. What it doesn't tell you, is that just because you now know who your best match is, it doesn't mean you'll get the person, nor does it mean that the choice remains the same for all time, nor does it mean that you can't still screw it up. For all that, you have to read the experiments.
Heck, SCP-1193 takes this to extremes. What is it? It's an impossibly long arm in a pipe, apparently attached to someone who has a regular, if odd, life. What does it mean? Everything you know is wrong. The Description could never, ever have reason to say that.
So, the big thing is to remember that just because the incremental step is known, we don't yet know the end conclusion. We won't know that SCP-2273 comes from a world populated by active SCP-1000 until you read the interviews. We know all about the problems with SCP-1875, but you don't get to understand the net conclusion until you go through everything.
Add a chronology. Add experiment logs. Add exploration logs. Add interviews. Just because we know how to protect ourselves, doesn't mean we know what it is. Just because we know what it is, doesn't mean we know what it means.
And, just because we know what it means, doesn't mean we know how to protect ourselves.
