I don't commute with any tools. I have pubic transit options throughout my ride, so if I have a mechanical issue it's quicker and easier to lock up, catch a bus or train, and deal with it on my way home. I've only even needed to do this a handful of times in nearly a decade of commuting.
For weekend rides where I'm farther from reliable transit, I'll take a pump, tubeless plugs, innertube, multitool, zipties, and quicklink tool+extra links.
