Well, you could do:

(add-hook 'muse-explicit-link-functions 'my-insert-skeleton)

and then:

(defun my-insert-skeleton (&optional link)
  "Get match and link and do something funky."
  (interactive)
  ;; If link is specified, we're publishing, so don't do anything.
  ;; Otherwise, an explicit link should always be at point, but just
  ;; to be safe, abort if this isn't the case.
  (unless (or link
              (not (looking-at muse-explicit-link-regexp)))
    (let ((description (match-string 2)))
      (setq link (match-string 1)) ;; might as well use the existing name
      (do stuff ...)))
   nil)  ;; don't stop processing here
