Hi, Ihor.

I have tried gptel inside emacs (I'm sorry, but I need to tell it) and I got this code:

#+begin_src emacs-lisp
(defun my-org-trigger-function (state)
  "Remove all tags when state changes to 'DONE'"
  (when (string= state "DONE")
    (org-toggle-tag nil 'remove)))

(add-hook 'org-trigger-hook 'my-org-trigger-function)
#+end_src

Surprisingly 8-) it doesn't work. Any help?

Best regards

I would like to remove every tag when changing to done state.

This is not working:

  '(org-todo-state-tags-triggers '((done ("(.*)"))))

This works though:

  '(org-todo-state-tags-triggers '((done ("Atag"))))

Yes, regexps are not supported in `org-todo-state-tags-triggers'.
You can use `org-trigger-hook'.
