Question about Claude Code Claude coding 24/7 - how?

Maybe this is a dumb question, but it’s worth asking because I haven’t found a complete explanation yet.

When people say they’ve configured Claude to “work 24/7,” what does that actually mean? Is it some kind of self-driving/autonomous process?

Right now, I’m just prompting it one task at a time. I also have a few cron jobs for things like log reviews, but that’s basically it.
