FOSS gamedev and creative worlds

I need to create a block that:
1. is diggable by bare hands
2. but sounds like a stone upon digging (like a stone that is being digged by axe)
3. and has some custom crack pattern (if that possible)

Probably I need to define my own group for this, but how do I do this? Maybe there is some mods that have custom groups I can look into?

You do not need an own group for that:

1. is diggable by bare hands
oddly_breakable_by_hand = 3

2. but sounds like a stone upon digging (like a stone that is being digged by axe)
has nothing to do with tool, just use the stone sound:
sounds = default.node_sound_stone_defaults()

3. and has some custom crack pattern (if that possible)
change the crack_anylength.png texture to your custom crack pattern.

Only one crack pattern can be used at a time; it's currently not possible to change the crack texture based on the block being dug.
