Disposable gloves like medical personnel use for messy repairs.
Two tubes.
Patch kit.
Tire levers.
All of the above is pretty easy to get to within a minute, it is in a ziplock bag.

Tire pump, either a Road Morph G or a Lezyne Micro Floor Drive pump with gauge. Sometimes in a pannier, sometimes on the frame, depends on how concerned I am about theft.

Spare spokes in the seatpost, held in place with a wine cork. The cork dried out and got loose so I had to wrap some electrical tape around it to keep it tight.

A multi-tool with bare minimum components, this one is in my pocket for quick access.

Some spare bolts threaded into a few extra spots on the frame where I store them, one of the bolts is a shoe cleat bolt.

The following is buried in the bottom of a pannier.
A multi tool that has a chain tool on it, some allen head wrenches and some normal wrenches, cone wrench.
Spare cables.
Spare chain quick link for my size chain.
Some lube.

I used to carry a cassette removal tool, but not sure if I will continue to carry that. Also had a short piece of (worn out) chain on a piece of cord to use as a chain whip with the cassette removal tool, and that also meant that I needed a crescent wrench too. I filed down two of the flats on the cassette tool to allow me to carry a smaller crescent wrench.

Varies slightly for each bike. On one of my bikes I need a 10mm open end wrench for a cantilever yoke. On another bike I need a T20 wrench.

You do not need any tools that you do not know how to use. I built up my bikes from the bare rims, so I know how to use all the tools I carry.

I whipped this out from memory, if I forgot something, I probably never needed it.
