01 · Understand the idea
In simple words
Imagine an assistant drafting a message to your class. Preparing the draft is different from sending it to everyone. An approval checkpoint lets you see the exact recipients and text before the action happens. If those details change, the old approval should not silently apply to the new action.
Two useful terms
Side effect: a change outside the conversation. Approval: permission for one specific proposed action.
