Seconding this -- I actually had copied "each column represents a step in the workflow and each row corresponds to an AI agent executing a task" to post a comment like this, but then checked through the comments to see if someone beat me to it, and here you are!

I'll add my terminology though, since it's slightly different. I think we're mostly agreed that "each column represents a step in the workflow" is fine. But for me the sheet represents an agent configuration, and each row is a specific job the agent performs.
