The auto tagger doesn't care about the talk page classification. I'd say the first page is definitely too long to be a stub

@Tom.Reding are you reporting that the en-wiki agreed definition of stub requires us to look for particular templates or tags on the page talk page?

@Reedy, in the "Alerts" window, I sometimes see "Long article with a stub tag" in those situations. AWB does not remove the tag in those cases. Is there a character-count grey-area where the alert is displayed, above which it triggers the removal?

@Rjwilmsi, no, but a talk page check just before stub-tag removal (so as to minimize unnecessary talk page queries AND to minimize removing desired stub tags) does seem like a good idea.
I'm just 1) curious what triggers AWB to remove a stub tag, and 2) reporting what I see as wrong behavior.

Here's what I found under https://en.wikipedia.org/wiki/Wikipedia:AutoWikiBrowser/General_fixes#Tagger_(Tagger):

• Removes {{stub}} if article has more than 500 words (comments, categories, defaultsort and persondata are excluded from word count).
  • Words in bulleted text are divided by 2 to avoid destubbing pages with big lists and little text.

At the same time, https://en.wikipedia.org/wiki/Wikipedia:AutoWikiBrowser/User_manual#ALERTS reads:

• "Long article with a stub tag." — Alerts if article has more than 500 words and a stub tag

Maybe you just hadn't activated genfixes when you encountered the alert? It is also possible that the alert configuration does not divide the words in bulleted lists by two (would like to read from a developer about that); that would be something I'd consider a bug.

I agree with the above that AWB shouldn't care about assessment templates when removing stub tags. They can often be quite outdated, and it is more likely they give incorrect information rather than the word count.

I agree, and I've changed the assessment to "start" on the talk page.
