I'm just a community mod, not a dev on the project, so take this with a grain of salt:

I believe the intent is that you get bidirectional selective sync between your terminal and the docs, so that if what's in the docs is out of date or wrong, then whatever you did to actually fix things can be synced back to the docs to reduce the friction of keeping the docs updated.

Thanks for this explanation. This makes sense.

To me, it seems like it's because the thing you're fixing is actually the "runbook" that's being run. Instead of separating the documentation from the code, they're married together so it's easier to keep them in sync because you aren't having to remind yourself to go edit this secondary location when you make a quick change.

I'm cautiously curious about something like this, although I haven't tried it personally.

Yes, seems like right now pendulum is going in other way and separation is no longer in fashion and now fashionable thing is to have everything in one place.

The idea seems interesting to me just cause I do not really like terminals and having something more visually appealing and with better history and comments is an improvement though I am also not sure if Atuin is best way to achieve all of that.
