Based off my own experience, I would have liked a list of example commands to get started with this mod, so I made one myself and put them in a convenient place for people to find. If you are having trouble with the formatting on some of the commands this might help. I have a few basic commands you can try (remember these are case sensitive) which you can use as a base to figure out how to format your own commands.

> spawn CyanLizard
spawns a cyan lizard

> spawn CyanLizard ID.-1.4241
spawns Sprinkles (a cyan lizard with ID 4241)

> spawn CyanLizard ID.-1.4241 Winter Voidsea
spawns Sprinkles with a winter head and gold color

> bind C down frame spawn CyanLizard
spawns a cyan lizard when you press C
(don't forget to type unbind_all to reset binds, and keep in mind you can set multiple commands to the same bind)

> at <cursor> spawn CyanLizard
spawns a cyan lizard at the cursor

> bind C down frame at <cursor> spawn CyanLizard ID.-1.4241 Winter Voidsea
spawns gold winter Sprinkles at your cursor whenever you press C

> kill type=Scavenger
kills all scavengers in the region

> destroy room,not_me,type!=CyanLizard
destroys everything in the room other than player 1 and cyan lizards

> group "at <cursor> spawn CyanLizard" "at <me> spawn CicadaA" "kill room,type=CicadaA"
spawns a cyan lizard at the cursor and a squidcada snack for the cyan at slugcat, killing the squidcada automatically

And some simple useful ones:
> rain_timer reset (resets rain)
> food 4 (gives 4 food
> food -4 (removes 4 food)
> karma 9 (gives max karma)
> invuln (makes you invulnerable to everything except death pits)

I hope you find some of these helpful if you were struggling to make certain commands work
