Post subtask status updates to threaded story conversations

Your subtask status changes don't appear in the parent thread, causing lost context. It posts subtask status into the parent thread and channel so teams regain context within minutes.

Overview

When subtasks move, conversation context often disappears and teams miss handoffs. This flow posts status changes directly into the parent story thread and channel, giving engineering leads and coordinators actionable context within minutes so triage happens before the next review.
