During February 2026, Toni Melisma developed a new calendar attendee notification control feature for the steipete/gogcli repository. This work introduced a --send-updates flag to the CLI’s calendar update and delete commands, allowing users to specify notification behavior for attendees with options for all, externalOnly, or none. Toni implemented the feature using Go, focusing on robust API integration and command-line interface development. Comprehensive integration and unit tests were added to ensure correct flag behavior and notification flow. The work demonstrated careful attention to test coverage and maintainability, addressing the need for granular attendee notification control during calendar changes or cancellations.
