Here's a short reminder for your RPG writing: skills aren't actors. They don't take actions. Saying, "A successful DC 15 Engineering check brings the machine back to operation," or "A successful DC 15 Sense Motive check exposes the lie," are both wrong, because a skill can't "bring" or "expose" things.

The thing that slips in the most often is when the skill use "shows" or "reveals" something, as in: "A successful DC 15 Survival check reveals red mud in the footprints." You'll sometimes see phrasing like this slip through in print, but it begs the question "reveals to whom?" The assumed answer is, of course, "the person making the check," so you're better off just rephrasing the sentence. Here are two ways to do it.

It's best to reframe a character as the actor, like this: "A character who succeeds at a DC 15 Engineering check can bring the machine back into operation."

Or it's sometimes okay to reframe the skill use as the result, like this: "The wainwright's duplicity is apparent to anyone who succeeds at a DC 15 Sense Motive check."

I'm not perfect; I put skills as actors all the time and have to catch myself. I'm sure many times I don't, but I'm trying.

That's all. I said this one would be short!
