Update on-call channel topic with current on-call engineer

Your on-call channel often shows the wrong owner, making responders waste time. Keep the current on-call visible so teams can contact them immediately each Monday.

Overview

When incidents strike, your responders shouldn't have to hunt for who's on call. This workflow publishes the current on-call owner into the team channel topic each Monday morning, so teams can contact the right engineer faster and begin triage immediately.
