Acquia Blog Uses FullCalendar Work to Examine AI-Assisted Contrib Maintenance

Maintenance work on Drupal’s Fullcalendar module anchors an Acquia blog post about AI-assisted contrib maintenance and maintainer burnout. Martin Anderson-Clutz, senior product marketing manager for Drupal at Acquia, published Vibe Coding Drupal: A Force Multiplier for Contrib on 25 June 2026. The post describes work with Jürgen Haas on Fullcalendar support after Drupal Dev Days in Athens and argues that AI tools can reduce repetitive maintainer labour without removing the need for human direction.

Martin says an initial AI-assisted pass to get the upgraded calendar running inside Drupal took less than an hour. The later work covered support for Fullcalendar v7, new themes, dark mode, a MultiMonth year display, sticky headers, test coverage, a reorganised settings interface, and Drupal 12 compatibility. He also describes AJAX loading of event data as a performance improvement for sites with large calendars, while noting that he redirected the AI agent when it proposed processing more data than necessary.

The post also covers tooltip support being developed as a submodule, with content loaded through AJAX and site builders controlling display through view modes. Martin says the tooltip implementation is awaiting community feedback before it is merged, after an existing Drupal.org issue thread was incorporated into the AI-assisted planning process. The next steps he identifies are completing tooltip support, tagging a release candidate, preparing a stable release, and updating the Events Calendar recipe, which uses Fullcalendar to provide a calendar view for event information.
