I think that that principle sounds good to me.
I do think for most posts (with exceptions for things like AMAs) I'd be less likely to add a tag if there's x amount of discussion of the topic in the comments than if there's x amount of discussion of the topic in the post itself. And I think I'd endorse this. Possible rationales include:
But I think that this doesn't matter a lot, and for simplicity it may be best to not get into that issue in the main guidelines page, since we're just presenting that as a rough heuristic anyway.
Maybe
The general tagging principle is that a tag should be added to a post when the post, including its comments thread, contains a substantive discussion of the tag's topic. As a very rough heuristic, to count as "substantive" a discussion has to be the primary focus of at least one paragraph or five sentences in the post or the associated comments.
This assumes we want to use the same heuristic for posts and comments, though your final bullet point seems to implicitly question this assumption.
(If we adopt this revision, other parts of the document may also need to be revised. For example, one can no longer infer an upper bound from the heuristic and the length of the post.)

I think it'd be good to either:
The gist of what I meant is just that the parent tag has to meet the same relevance standards as any other tag, and not be included merely because of its logical relation to its child. I didn't mean to suggest—though the passage you quote is worded in a way that seems to make that suggestion—that unless the post covers material specific to the child tag, its parent should not be tagged. I have revised the text to make this clearer (and fixed the link you mentioned in the other comment—thanks).
When a post is tagged with a tag which is a proper subset of another tag, you should add this broader tag only if it is also sufficiently relevant. For example, a post tagged with neglectedness should also be tagged with importance, tractability and neglectedness framework if it also has sufficient discussion of the ITN framework as such, rather than just of neglectedness specifically.
I'm not sure I understand this, or maybe I'm not sure I understand what the problem these sentences are aiming to solve is. What about, for example, a post that's entirely about 1 aspect of AI alignment/governance for which we have a specific tag? I think it should also get the AI alignment/governance tag, even if every paragraph is about that 1 aspect, because it would be good for the post to be findable via those broader tags. It would be a bit odd for more focused posts to be excluded from those broader pages even in cases where they're great, have high karma, etc.?
(But mostly these guidelines look great, as we discussed earlier, and thanks for making them!)
- Check that the tag you would like to create does not exist under a different name. You can see a list of all tags here.
That link goes to the tagging dashboard. I imagine it's meant to go to the Wiki homepage (formerly the tag portal)? But I'm unsure, since I think the Wiki homepage often doesn't list all tags - there've been a few times I've tried to make a tag but then discovered either that one or a related one already existed, could've been found via the search bar, but weren't on the Wiki homepage. (But maybe that's changed now.)
So I think the link should be changed to the Wiki homepage + the phrasing should be something like "You can use the search bar to see if a tag with a given name exists, or see a list of all tags here (except possibly new tags that haven't yet been added there)." But I'm not sure.
I vaguely share your feeling that posts "count for more" than comments, though I can't think of a better heuristic than the one I proposed, so for simplicity I just used the text in my previous comment. Feel free to refine it.
I also removed the paragraph referring to the upper bound, and revised the paragraph that followed it, for unrelated reasons. (I think it's something someone added to the Google Doc I circulated, which I didn't initially read very carefully. As it was worded, the paragraph gave readers advice on how to write posts, rather than on how to tag those posts, which should be the focus of the Tagging Guidelines.)
