Background

As part of T385502 - mobile summaries pilot, we want to "introduce a pre-generated summary feature as an opt-in feature on a the mobile site". In order to do that, we need a first build a call-to-action modal, and then present this modal to users. Similarly to how we launched dark-mode on mobile, we can create a CentralNotice campaign + banner to show this custom modal to a small percentage of mobile users.

User story

• As a casual Wikipedia reader, if I saw the option to get a new summary feature on mobile, I might be interested and enabled that feature.

Design

The design and development of the CTA modal is covered in T387598 - Build CTA modal.

Requirements

Create a new CentralNotice campaign and banner that will show the custom modal to a percentage of users.
Campaign parameters:

• The modal should only be shown to users once, and once they have dismissed the modal, it should not be shown again.
• The modal should only be shown to English speaking users
• The modal should only be shown if the new summary extension is active on the given wiki.
• List of wikis to show campaign for [TBD]
• Sampling rate [TBD]

Banner code

The following banner triggers the CTA modal to open only if the user:

• is on enwiki
• is using the minerva skin
• is on a page that has an available summary
• has the summaries feature turned off (to not show if it's already on)

This can also be tested on beta cluster since beta has the dbcode enwiki.

<script>
  const isEnwiki = mw.config.get( 'wgWikiID' ) === 'enwiki';
  const isMinerva = mw.config.get( 'skin' ) === 'minerva';
  const hasArticleSummary = document.querySelector( '.ext-article-summaries-container' );
  const isExperimentDisabled = mw.user.clientPrefs.get( 'ext-summaries' ) === false;
  
  if ( isEnwiki && isMinerva && hasArticleSummary && isExperimentDisabled ) {
  	mw.hook('ext.articleSummaries.cta.open').fire();    
  }
</script>

Banner settings

Campaign configuration
