Let use rate limit codex chats manually

I’m not sure if it’s just me, but my codex chats have begun to flail around in recursive loops doing nothing for hours. Last night I left an agent with a task to write a relatively simple script when I went to bed. I had 90% of my weekly pro 500 usage left. When I woke up, I had 0% left, from 2 chats running. The chat didnt even do the requested task, just flailed around doing god know what for ~8 hours.

My suggestion is let us limit the % of weekly usage, or a nominated credit amount, a task is allowed to use before being limited. Had this functionality been implemented, I would have said use no more than 10% of weekly limit, and then woken up to find out it flailed around for an hour or two, not 8.

Thanks
