I cant seem to find the chisel section on the crafttweaker "read the docs" guide, and you luckly have examples for "Inspirations" here, at least.
Are they still the same as the Minetweaker codes?

Looking at compat/chisel/Carving.java , I think the new codes are:

mods.chisel.Carving.addGroup(String name);
mods.chisel.Carving.addVariation(String groupName, IItemStack stack);
mods.chisel.Carving.removeGroup(String name);
mods.chisel.Carving.removeVariation(String groupName, IItemStack stack);

with the command /ct chiselGroups to output Group Name in ctlog

EDIT: tested with mods.chisel.Carving.addVariation("bloodMagic", <bloodmagic:blood_rune:0>); is working :D

Thanks, i love u!!
