Briefly: I'm continuing to discover your pages, and some of my questions seem to be already answered elsewhere, so it's partly because I'm new to your product and am still discovering it.
Part of the issue I see here, reminds me of the old game of "Telephone", where a message gets progressively blurrier and garbled, the more it's passed on. Here, it starts where some editor perceives a problem at an article, and slaps a template on the article. There are a finite number of these templates, and often the template content is only an approximation of what the real problem is. So, that's the first whisper. Secondly, the editor who places it is encouraged to use the |reason=
parameter, but the great majority do not. Whisper #2. Then, some part of your software finds the tagged article, and tries to assign it to one of the six tasks, which are only very roughly aligned with maintenance templates: whisper #3. Then, there's the doc page, the on-page guidance, and the understanding of a new editor to take into account. How close to the complaint identified by the original template are we now? I can easily see how a stepwise blurring of this sort could have led two separate editors at w:Battle of Khresili to make good-faith edits that were not helpful.
I presume that you control generation of the edit tags, and can add as many subtypes of copyedit tags as you wish to; is that correct?. If so, I would recommend that the tag, and the task, hew very closely to the maintenance template problem that is identified on the page. Maybe this means several dozen more tags or subtags, and a longer doc page with more subtasks (or a hierarchy of task pages) but I think that would reduce the blurring and keep a newcomer focused on a task that is as closely related to the actual problem identified on the page as possible.
In the case of the {{Peacock}} template, I assume it enables the choice of Battle of Khresili only for editors needing to be assigned a Copyediting task, correct? Imho, that is way too broad, and ideally, it should be only for a specific subtype of copyediting, namely, searching for peacock terms and removing them or altering them. An editor should not be led to an article that has some peacock terms, and told it needs, or could benefit from, general copyediting. A Peacock template is not a sign that the article needs general copyediting, and indeed, imho, w:Battle of Khresili does not need general copyediting, so if newcomers were told that it did, they were lead astray, in my opinion. (As a side issue, I don't think the article has any peacock terms, either, and I've raised that at the article talk page, but that's not something you need worry about as is is unrelated.)
I won't have any suggestions about mentorship for you until I have tried it out myself. Haven't yet found the time to even browse the dashboard and see how it works, so I'm still a completely newbie in that respect. Mathglot (talk) 01:10, 18 February 2023 (UTC)
