Overnight autonomous coding

At work we've been prompted about running Claude Code overnight. The suggestion came in form of a document that loosely outlined how this could be done... use git worktrees, make tight specs, no commit to main, static code analysis and lining etc. Very high level. Had a bit of sales pitch smell to it, but has enough content to peak my interest in spite of it.

I looked at reddit to verify if this is even an idea that could be taken seriously. I could only find a couple of reddit posts with little actual information and usually from about 4-6 months ago so not much credibility for today.

I'd like some more opinions on the matter. So... For today, does the idea of running AI agents overnight to do coding tasks make sense? If so, what use cases does it make sense for and what would a sensible setup look like? What are the trade-off and practical costs you may face?
