You can define a function with `org-map-entries' that adds (for example) a
tag :github: to all headers with the property GITHUB:
#+begin_src emacs-lisp
(defun add-github-tag ()
(interactive)
(org-map-entries (lambda ()
(save-restriction
(save-excursion
(org-narrow-to-subtree)
(goto-char (point-min))
(end-of-line)
(insert " :github:"))))
"+GITHUB={.+}"))
(add-hook 'org-mode-hook #'add-github-tag)
#+end_src
