I think it depends on what you mean by repeatable tasks. I reuse the critical handoff agents quite a lot since they are basically just set up to help spot bias and errors. I kind of reuse the top agent. I have a few "core" configurations that I can add to. So one will know our network, one will know our data architecture and so on, to keep them a little more focused. So for this specific agent that I described, I'll add a few lines on what I'm considering to the configuration, that I'll not reuse for anything unrelated to Microsoft Fabric. I've tried using these "core" agent configurations as hand-off agents in the past, but it doesn't seem to work well in our setup which is very isolated because we're NIS2 compliant.

I don't usually go back to the original prompt. I've actually done it a few times in regards to the presentation, to get some refined images but usually I'll start a new prompt.
