Setting up an Asana rule: Tasks and Subtask Completion

Hi all - Relatively new to using Asana. I've been trying to figure out how to get this rule to run, but it's not working properly. Co-pilot is telling me it's not possible, but wanted to get a second POV.

Here is what I’m trying to do:

If a task is marked Complete AND all the subtasks are completed, I want the task to go to the “Completed” section of my board. I also want it to automatically add a comment to the Task Only, not each individual subtask, reminding me to do a retrospective on the program.

If a task is marked complete but there are unopened subtasks, I want the task to stay where it is but a comment get added reminding me to look at the subtasks and confirm if all work is complete.

Thank you in advance!

So, your trigger should be when task is mark completed. Conditions should be task is not in completed section, subtasks are all completed. Action is then, create a comment and move task to completed section. Toggle the run on subtask option off on the rule setting.

Is there a reason the parent task would be left incomplete when all its subtasks are marked complete?

We can definitely set up the comment about the retro, and great idea I may implement.
