I don't think I've ever /resumed a Claude Code session even once. What do people use that for? The way I use it is to make a change, maybe document the change, and then I'm done. New session.
I have like 15 concurrent sessions I leave up for weeks, 50% Codex 50% Claude Code, even though I know they work better with fresh context. Then again I also always have least 200 browser tabs up. I probably just have a mental illness.
Most of the time it's when I want to go back and have a skill made for future reuse, but with remote control I've had some sessions open for remote diagnostics and it just works better than starting from scratch - even having lessons learned to create memories and update Claude.md.
I know it's wasteful but often I've got a surplus of tokens and not enough of my time - so it's a trade off I've been fine with.
I'd use it if I hit the 5 hour quota mid-change and then came back later in the day in a new terminal (depending on the input/output ratio of my now un-cached context, of course).
