It’s so cool that I would like to document it. ;-)  Sorry to not dive in
the code first.

Ah yeah, that makes sense.  Now, no error but nothing showed:

--8<---------------cut here---------------start------------->8---
$ cat $GUIX_EXTENSIONS_PATH/guix/extensions/bar.scm
(define-module (guix extensions bar)
  #:use-module (guix scripts)
  #:export (guix-bar)
  )


(define-command (guix-bar . args)
  (category extension)
  (synopsis "a bar with beer")

  (pk "dumb"))

$ guix --help | grep bar
--8<---------------cut here---------------end--------------->8---
