Org mode tag inheritance in agenda custom commands

Question

I want to create Org Mode agenda views or sparse trees with tag inheritance disabled so that tagged headlines are included but children are not. I do not want to turn off tag inheritance globally. I thought this could be accomplished by setting options for custom commands, as in the following example:

 (setq org-agenda-custom-commands
    '(("y" tags "tag1|tag2"
       ((org-agenda-use-tag-inheritance nil)))))

However, the resulting agenda view includes all children of the tagged headlines. The desired result can be achieved by disabling tag inheritance globally, (setq org-use-tag-inheritance nil), but I do not want to disable tag inheritance globally, only for the agenda custom command.

Alternatively I have tried to create the same filter using a sparse tree:

   (setq org-agenda-custom-commands
    '(("Y" tags-tree "tag1|tag2"
      ((org-show-context-detail 'minimal)))))

But this returns a sparse tree including all children and ancestors of the tagged headlines. Again, if I disable tag inheritance globally I achieve the desired result. What am I am missing?

Answer 1

The docstring of org-agenda-use-tag-inheritance says that:

In tags/tags-todo/tags-tree agenda views, tag inheritance is controlled by org-use-tag-inheritance.

Both of these work as expected even when org-use-tag-inheritance is non-nil globally:

(setq org-agenda-custom-commands
      '(("y" tags "tag1|tag2"
         ((org-use-tag-inheritance nil)))))

(setq org-agenda-custom-commands
      '(("Y" tags-tree "tag1|tag2"
         ((org-use-tag-inheritance nil)))))
