Flag mid-cycle issues added to an active Linear cycle and post a Discord scope alert

When an issue is assigned to a Linear cycle that is already in progress, this workflow detects that the cycle's planned scope has changed and posts an immediate alert to a Discord channel. The alert names the issue, its estimate, the assignee, and the person who added it, so the change is visible the moment it happens rather than at cycle end.

Run this when your team commits to a cycle scope at planning and you want a lightweight guard against silent additions. It is ideal for squads that protect focus time and want every mid-cycle insertion to be a conscious, discussed decision.

1. 1A Linear webhook fires when an issue is created or updated.
2. 2A logic step checks whether the issue's cycle is the team's currently active cycle and whether the cycle's start date has already passed.
3. 3A second logic step filters out issues that were part of the original committed set, keeping only genuine mid-cycle additions.
4. 4An action step reads the issue's estimate, assignee, and the actor who made the change from Linear.
5. 5The workflow posts a formatted scope-creep alert to the chosen Discord channel.
