After a new installation with Homebrew, this was a surprising result:

$ ki -h
Usage: ki [-h] [--version] 

  -h, --help                Prints help
  --version                 Print version

(An aside -- I see you're using JLine3, such a nice library! You might consider handling command-line option flags with Picocli via the picocli-shell-jline3 dependency. The two libraries work together nicely by design.)
