org-after-todo-statistics-hook allows you to do something to a node after its statistics cookie got updated. Unfortunately, it does this only for TODO subheadings and it doesn't work with checkboxes.
Use case: Grading assignments. Each assignment is a subheading. Each student's work for that assignment is a plain list item with a checkbox. When I finish grading one of them, I tick off the checkbox. At this point, I want the heading's TODO status to change:
- If all items are complete, change it to DONE.
- If there exist both finished and unfinished list items, change it to INPROG.
- If all items are still open, change it to TODO. (This could happen if I mistakenly ticked a checkbox and then un-ticked it.)
This should then cascade upward to the parent's statistics, all the way to the top level, so I can see at a glance (even with all top-level trees folded) that there is something remaining to grade.
I don't want to use subheadings for each student's work, because then my TODO agenda views will get cluttered with multiple entries per assignment.
Actually... after a little more poking around, the problem seems to be that org-update-checkbox-count refers to no hooks whatsoever. Should it go toward the end, here? (Untested.)
(mapc (lambda (cookie)
(let* ((beg (car cookie))
(end (nth 1 cookie))
(percentp (nth 2 cookie))
(checked (car (nth 3 cookie)))
(total (cdr (nth 3 cookie)))
(new (if percentp
(format "[%d%%]" (/ (* 100 checked)
(max 1 total)))
(format "[%d/%d]" checked total))))
(goto-char beg)
(insert new)
(delete-region (point) (+ (point) (- end beg)))
(run-hook-with-args 'org-after-todo-statistics-hook

After dinner, I tested the change that I had speculated about, and... it works exactly correctly.
* TODO Test A [0/2]
** TODO Test B [0/2]
- [ ] 1
- [ ] 2
** TODO Test C
C-c C-c on "1" (with my hook function[1]):
* TODO Test A [0/2]
** INPROG Test B [1/2]
- [X] 1
- [ ] 2
** TODO Test C
C-c C-c on "2":
* INPROG Test A [1/2]
** DONE Test B [2/2]
- [X] 1
- [X] 2
** TODO Test C
So I'm submitting this as a TINYCHANGE patch. Do with it as you will, although I will keep using it locally until something better comes along.

Ok, I'll have a look. Not at my computer now.
I do think this issue qualifies as a bug (albeit minor). The real behavior
deviates from the documentation (in a way that's difficult to justify
logically). IMO it should be fixed, or the documentation should explain
that the after todo statistics hook doesn't work for checkboxes without
"require"ing org-checklist.

Using "org-checklist.el" was just a suggestion.
`org-todo-statistics-hook' is used for TODO (i.e. headlines) and
`org-checkbox-statistics-hook' is used for checkboxes (i.e. lists).
I see no bug here (although they aren't called with the same arguments,
but that's another story).

I'm sorry to be a pest, but I did get sent on a wild goose chase by what is either a/ faulty behavior or b/ a faulty docstring. The docstring of org-after-todo-statistics-hook says: "Hook that is called after a TODO statistics cookie has been updated." Well, that isn't true. Changing a checkbox updates a stats cookie, and the hook is *not* called. And it took more than an hour to figure that out. So, for the sake of users dealing with this in the future, let's at least fix the docstring then.
It isn't clear to me how to use org-checkbox-statistics-hook or org-todo-statistics-hook for my use case. This isn't about "alternative ways of collecting statistics" (org-checkbox-statistics-hook's docstring). I'm willing to switch to that, but less willing to trawl through the org sources (again) to figure it out. At least, not today.
hjh
For reference, from http://orgmode.org/worg/doc.html#hooks:
org-checkbox-statistics-hook nil
Hook that is run whenever Org thinks checkbox statistics should be updated.
This hook runs even if checkbox rule in
`org-list-automatic-rules' does not apply, so it can be used to
implement alternative ways of collecting statistics
information.
org-todo-statistics-hook nil
Hook that is run whenever Org thinks TODO statistics should be updated.
This hook runs even if there is no statistics cookie present, in which case
`org-after-todo-statistics-hook' would not run.
org-after-todo-statistics-hook nil
Hook that is called after a TODO statistics cookie has been updated.
Each function is called with two arguments: the number of not-done entries
and the number of done entries.
For example, the following function, when added to this hook, will switch
an entry to DONE when all children are done, and back to TODO when new
entries are set to a TODO status. Note that this hook is only called
when there is a statistics cookie in the headline!
(defun org-summary-todo (n-done n-not-done)
"Switch entry to DONE when all subentries are done, to TODO otherwise."
(let (org-log-done org-log-states) ; turn off logging
(org-todo (if (= n-not-done 0) "DONE" "TODO"))))

This is because checkboxes (plain lists) are not related to TODO
keywords (headlines). There are TODO statistics cookies and checkbox
statistics cookies. Only the former run a hook once updated.

Please provide a patch if you think a docstring can be improved.

Thanks for clarifying. I hadn't understood that distinction.
It occurred to me, after I sent my last e-mail, that someone might want one action after updating todo statistics and a different action after updating checkbox statistics. Using the same hook for both wouldn't be correct in that case.
So let me update my issue report/feature request:
-- If there is a hook to do something after updating todo statistics, then it would make sense to have a hook for updating checkbox statistics as well. That hook should be called with the same arguments (n-done n-not-done) so that the user could use one function for both, if desired.
I can do this pretty easily and update the documentation. I don't have FSF papers signed, but I'm willing to get that ball rolling as well.
But before spending any time on that, I want to ask if this is okay. I understand the objection against pressing org-after-todo-statistics-hook into service for checkboxes. If there's an objection against simply *having* a hook for checkboxes, I'm afraid I don't understand that.
Thanks for your patience,
hjh

I have no objection to this.
Note that this hook can be tricky to use because checkboxes are local to
the list. So adding a global effect to it (e.g., switching TODO state)
will sometimes fail. In the following example
* Headline
- [X] list1:item 1
- [ ] list1:item 2
Paragraph
- [ ] list2:item 1
- [ ] list2:item 2
checking "list1:item 2" will trigger the hook with (2 2) as arguments,
which may be surprising. I suggest to add a word of warning in the
documentation.
Thanks for working on it.
