@Niharika @Prtksxna I've made a list of where the links should point to, based on the task description from T237039. I was unsure about some of them - would you mind checking the table and filling in the gaps?

• I don't think the groups need to be linked to anything. The documentation about these groups if we must, but I don't think that is necessary.
• Do we know the users' home wiki, like the one they signed up on? If yes then we can link to their Talk page from the user name.
• The wiki's names could link to their User page on that wiki.

@Tchanders I updated the task description. The only weird thing is that there is no central global contributions page so we need to link to the toolsforge tool for global contribs.

@Niharika Adding this link would only make sense for WMF sites:

User's global contributions page (in the guc tool - https://tools.wmflabs.org/guc/, no other place to do that)

If a third party was using Special:Investigate, it wouldn't make sense to send them here; they might get no results, or nonsensical results if there's a username match.

Oh, good point. Can we do it conditionally in the code? Would that make sense to do in the extension or elsewhere?

@Niharika I guess it might be a little odd to do this in the extension, since the extension is used on third party wikis. We could add a link via the WikimediaMessages extension, but I'm not sure how straightforward it would be to add a link to each table cell, since we'd have to run a hook after we get the results.

Would it be helpful to put up a single link to this tool (not linking to a particular user) at the top of page, via WikimediaMessages? Or is that too generic to be of much use?

Another thing that occurred to me was that having the same link in every cell with a given user's name might be a bit repetitive (whereas the wiki-user-page and wiki-user-contributions links will all be unique).

@Tchanders Let's take that to a new ticket. I'll check-in with the users and Prateek and see if we can do this a different way. We can have a follow-up ticket for that link. For now it's okay to ignore it. I'll update the task description.

Removed the following from the task:

Username	"Global Contributions"	User's global contributions page (in the guc tool - https://tools.wmflabs.org/guc/, no other place to do that)

Wiki	Wiki's name in canonical form	On-wiki user page (red or blue link depending on page existence)

Have been discussing this with @dmaza - this is trickier than a local user page because of being an external wiki. Could we make a separate task for this?

(I also wonder if a red link might be misleading since the text is the wiki name, but that might just be me!)

Yeah, that works for me. Will update the task.

Change 570471 merged by jenkins-bot:
[mediawiki/extensions/CheckUser@master] Add links to Special:Investigate preliminary check results table

https://gerrit.wikimedia.org/r/570471

The wiki column links to the User:$user page for the correct user and wiki.

The edits column links to the Special:Contributions/$user page for the correct user and wiki.
