Hi,
The `org-insert-link' function has the `auto-desc' variable to suppress
user prompt for link description. It worked accordingly its intention
(as I understand it) a couple of months a decade ago, after that the
logic was broken. Actually the behavior is rather strange: users may
edit description only when it is not identical to link path (target). I
am attaching a patch that removes this variable with hope that always
prompting the user for description is more consistent behavior.
Actually during last week completion stored link by its description has
been restored, storing link has been changed to prefer nil as
description to the path when nothing meaningful may be added. So
behavior have become more close to original one.
I have an idea how to fix the code to bypass the description prompt if
path is completed by description discarding identical path and
description, but I prefer to drop the confusing variable and not depend
on the means how the link was selected from the list of stored items.
Have I missed something and unconditional prompt to edit link
description may be undesired in some cases?

Subject: [PATCH 1/2] ol.el: Always prompt for description in `org-insert-link'
* lisp/ol.el (org-insert-link): Do not bypass code trying to generated
description and prompt user when link path and description are
identical. Make behavior of description prompt more consistent.
Remove confusing `auto-desc' local variable. Originally the variable
was added with implementation of completion of stored link target by the
description in the commit 1e34c5d34 Bastien Guerry, "org.el: Fontify
links to current buffer when inserting a link",
2012-08-03 14:08:20 +0200. The feature was broken soon by the commit
7f096ad37 Tony Day, "org-insert-link: Use ido when inserting links",
2012-10-12 14:39:53 +1100. Last decade users were not asked to edit
description in the case of the same link target and description
(a remained side effect of 1e34c5d34). Recent commit 0432f4fe6 Max
Nikulin, "ol.el: Restore complete by description for insert link",
2022-09-10 17:23:13 +0700 restored completion by description.
Due to the commit 4fc2c8dd8 Ihor Radchenko, "org-store-link: Default to
empty description for target/custom-id links", 2022-08-10 13:25:26 +0800
description identical to link path became a more rare case.
An alternative would be fixing condition to allow users to edit
description when it is the same as the path, but use stored description
without additional interaction when the link is chosen by description
completion. Despite it was likely the original intention, always asking
the user to confirm or edit description may be more consistent behavior.

AFAIU, this particular behaviour is undocumented. If it is used by some
other code, let's make tests for it, document, and fix in a better, more
explicit way.
I am unaware about the code using this link==description behaviour.
Applied onto main.

Bastien,
Could you please check the ongoing changes in this area
(storing/inserting links)? The code in this area is old, confusing, and
not fully documented. I'm afraid that we may break something in the
process of refactoring. If you see some dangerous changes, please let us
know.
