The instrumentation that already tracks the user’s behavior on the newcomer homepage and in the suggested edits module should continue in the same way. The only difference should be that “add a link” should be a new task type that can be distinguished from the legacy link task.
Likewise for the help panel, which will contain guidance specific to “add a link”, the instrumentation should work the same way as for legacy suggested edits, except it will include an indicator for this new task type.
Likewise for the post-edit dialog, which should use the same instrumentation as it already does, except including an indicator for this new task type.
