Adding functionality to a minor mode

[goncholden via Users list for the GNU Emacs text editor <help-gnu-emacs@gnu.org>]

I have made a minor-mode with some defvar and defun. Have added some functionality
for comments, and put everything in the following function definition.

(defun rich-annotation-tools ()
"Aggregates annotation tools for comments."
(rich-annotation-font-weight)
(rich-annotation-low-contrast)
(rich-annotation-keytrigger))

I would expect to add "(rich-annotation-tools)" in define-minor-mode. Would I introduce it
within the "(when rich-minor-mode" part?

;;;###autoload
(define-minor-mode rich-minor-mode
"This is the description."
:lighter "rich" ; indicator in mode-line

(font-lock-remove-keywords nil rich-font-lock)

(when rich-minor-mode
(font-lock-add-keywords nil rich-font-lock 'append)
(set (make-local-variable 'jit-lock-contextually) t) )

(rich-annotation-tools)

(when font-lock-mode
(if (fboundp 'font-lock-flush)
(font-lock-flush)
(with-no-warnings (font-lock-fontify-buffer)) )) )
