The submitter could decide and curate what is useful to be shared, whether that’s exact message logs, or the subagents and skills they think made the difference.

I really have no idea. There's almost no good mapping from conversation to code. Take e.g. https://github.com/Protonk/PAWL

There's...thousands of conversations in dozens of different configurations over months to make that. What...out of that do you want to know? What do you deserve to know by dint of my making a submission?

Those aren't rhetorical. I think if you can answer those two, that's a fair start. Good luck lol.
