mkdir -p "$(dirname "$DUCT_OUTPUT_PREFIX")"

duct 0.0.1

I think it is worth `os.path.expanduser` the prefix

I disagree. The problem is that the shell script was not written correctly to expand the ~ itself. Paths passed to programs should already have tildes expanded; it should be the caller's responsibility, not the program's, to expand them.

for a in "$@"; do

damn shell (zsh here) assumes that unquoted ~ is indeed part of the path and should be expanded -- didn't know :-/
