I published a nearly identical tool, referencing the same paper, a few weeks ago :) Although I implemented a listwise algorithm instead of pairwise as described in the paper; ends up being a lot faster.

       1  The train arrived exactly on time.

I've found that when I'm cloning submoduled private repos via YK-backed SSH key, I'll need to touch multiple times but there's not always text in the terminal notifying me to do so. Easy to miss the small flashing green light.

Is it possible to add it to ssh-agent once?

No, the idea behind yk-backed keys are that part of the secret lives on the yubikey and can't be extracted.

So you need to approve the usage of that secret by touching the yubikey.

Well, if it's the same git server using the same SSH key for every repo, can't you still use SSH's ControlMaster to open the connection once and leave it open?

Yeah could do. I do this for some SSH hosts but not all.
