This task involves the work of introducing a Check that would prompt people to reconsider adding an external link to the body or lead section of an article, per en:WP:ELNO.

Story

• As someone attempting to add an external link to the body or lead section of an article at en.wiki [i], I would value being made aware that me doing so has the potential to violate a policy so that I can A) avoid the negative impact(s) me doing so could cause and B) better understand what people do and do not consider useful contributions to Wikipedia.
• As an experienced volunteer motivated to ensure people visiting Wikipedia find useful and reliable information presented in a consistent manner, I want people who are attempting to make edits that could cause the opposite to happen to be made aware when they're at risk of doing so, so that I relieve myself of the work of addressing these issues retroactively and direct my attention to things I consider to be higher priority.

Background

mediawiki.org:

@Trizek-WMF and @KStoller-WMF, seeing edits like this one, are we doing enough to let newcomers know that the "add a link" task is for internal links to other Wikipedia articles, not external ones (which violate w:WP:ELNO if placed in the intro or body)?

i. TODO: learn the extent to which this policy is in place across Wikipedias

Thank you to @Sdkb and @KStoller-WMF for prompting us to create this ticket.
