Editing-team is working on adding new validation for user signatures in preferences. This is motivated by DiscussionTools, which needs the signatures to be "machine-readable" so that we can reliably detect users' comments, but other tools would also benefit and some of these have been requested a long time ago.
We're working on:
- T140606: Check user signature for linter errors
- T237700: Require user signatures to contain a link to their user page, talk page or contributions
- T230652: Tilde stripping in signatures is inadequate
This task is mostly to work out how we're going to consult and announce the changes, which will happen together for all three changes, and maybe other things which apply equally to all of them.
