Does This Look Like A Crack?
I just flipped my carbon kuota kredo road bike over to clean the cassette and noticed this. Getting a little paranoid. Is this a crack? It's the small gash near the deraulier hanger. When i run my finger or nail over it there is a very very slight depression

I see the pictures, but not sure which squiggle you are referring to. Carbon can be hard to figure out by picture over the internet. Does it feel like a crack ?

the way that area is marked up, it seems more likely that it's a scratch from putting the wheel in. But it could be a crack

Nothing wrong with your post. The fault is on my end.

No, it looks like a mark in the clear coat to me.

Have your LBS look at it. Can't really tell from those pictures.

You Know!? For Kids!
I am not a structural engineer nor have I stayed in a Holiday Inn Express, but to me, that looks like a chip in the clear coat.

Doesn't matter if it's a crack or not. It's on an unstressed part of the frame.

I'm going with superficial scratch.
However, if you remove the rear wheel and gently pulled on the derailleur/hanger, a crack would probably move. Don't reef on enough to break stuff though.

I'm looking at a crack/chip. Doesn't matter the pic... the flaw is below the axle centerline and on a free edge of a member in compression. Whatever the flaw, there is no chance of it affecting the structural performance of the frame. My guess is it is a chip in the clear coat caused by the wheel axle; but even were that chip to go through to the carbon, it doesn't matter because of the location of the flaw.
