I've just had a look in my courier bag.
CO2 inflator, two carts, pump, two tubes, three levers, multitool, one cabletie, O-rings for Dinotte light, spare battery pack for Dinotte, spare front light (cheap Cateye LED), cycling cap, spare socks, anti-commando pants, bottle opener, electrical tape.
(The jersey pocket kit is CO2 inflator, one spare cart, two tubes, levers, multitool. Sometimes I get nervous and attach a pump to the frame with electrical tape- there's spare tape wrapped around the seatpost)
