New visitors to the site are routinely linked to the Tour, which introduces certain banned topics: Questions which are off-topic, primarily opinion-based, have too many possible answers, or would require an exceptionally long answer.
It's reasonable to expect new users to follow these guidelines.
However, new users sometimes find their questions closed or downvoted for violating a rule not explicitly described in the tour, especially posting certain topics: Questions about rule intent, designer reasons, alignment questions (though not always), and product recommendation questions, to name a few.
Another common mistake is failing to add a system tag, something which isn't specified in the Ask a Question screen.
Is there a list somewhere of all the rules a user is required to follow when posting questions, especially a complete list of question types which are likely to be closed?
If not, could one be made and presented to new users along with the Tour?
[tag] closed:no
won’t accurately deduce if a tag is off-topic; as a rule we don’t go back and close questions when things are deemed off-topic. Anyway, as the alignment question meta explains, there are plenty of on-topic alignment questions; it’s just the most problematic (and therefore common) alignment questions—those about what alignment something is or isn’t—that are off-topic (and, really, they are off-topic because they are invariably primarily opinion-based). \$\endgroup\$
