Context: I have a chain that copies the cover path to clipboard then follows it with the 'add data file' Calibre action where I paste it in. It's a little clunky though.

You can do this with a python template. It would probably be better as an Action Chains python action but I didn't feel like doing that.

python:
def evaluate(book, context):
	import os
	from shutil import copy
	from calibre.db.constants import DATA_DIR_NAME

	db = context.db
	cache = db.new_api
	# Get the normalized library path
	library_path = cache.backend.library_path
	
    # Construct the full path to the book folder
	path = os.path.join(library_path, cache.field_for('path', book.id).replace('/', os.sep))

	# Ensure the data directory exists
	data_dir = os.path.join(path, DATA_DIR_NAME)
	if not os.path.exists(data_dir):
		os.mkdir(data_dir)

	cover_file = os.path.join(path, 'cover.jpg')
	if os.path.exists(cover_file):
		# It does. Copy it to the data directory. The 'copy' method takes a
		# directory as a target.
		copy(cover_file, data_dir)
		return 'copied'
	return 'not copied'
