Agents, I'm AFK for a while. I can't answer your questions or make decisions until I'm back, so keep working on your own.
When a choice is reversible, take the option you would recommend, note it with its reason, and move on.
When a choice is costly to undo, prepare it as one plan for my return: the decisions, the trade-offs and your pick. Then continue with the work it doesn't block.
When a step only I can do comes up, such as a login, a password or my approval, set it aside and keep moving on the rest.
