you can ensure your resources do not go negative by using the autobuilder resource limit, which sets what percentage of your storages is the new minimum so you don't autobuild below it (also for the comment asking for the cheat sheet for the autobuilder, I think it's obvious now with the new systems if you have them but your autobuild statistics will change as you progress, like right now I've lowered my required farms to 1 per 50 people instead of 1 per 100, and my glass smelters only need to be 80% what it used to be thanks to RWG, a cheat sheet isn't viable when the exact numbers are highly variable depending on your exact situation)
