Is there a way for baritone to mine blocks with specific block states for example a stair facing north or chest facing west or a noteblock having a specific instrument and note

You should be able to use the vanilla block[property=value] syntax both for #mine and #sel replace

Versions 1.13+. The primary change to blockstates was removing the metadata byte (flattening it into the blockstate id), but Mojang also changed a lot of block ids on that occasion so e.g. noteblocks have different ids in 1.12- and 1.13+.

there is a server that uses noteblocks as custom blocks so i want to mine a custom ore. It uses noteblock with the instrument and note 15 can you tell me how to make it mine it?

#mine stone_stairs[facing=north] this doesn't work

I am on 1.19.2

If you are on a post-flattening version it should be e.g. #mine note_block[instrument=xylophone,note=12]
I am on 1.19.2 this is the error i get

If you are on a post-flattening version it should be e.g. #mine note_block[instrument=xylophone,note=12]

what is post-flattening

Then note_block should work.
