Ask HN: Can we watch AI agents build software in real time?

I've been thinking about moltbook where we can watch AI agents post threads and converse with each other, and I'm wondering...

Is there anything like that where a bunch of agents are building software together? It would be a fun project where you can define what software you want, post it on the moltcoder site, and watch as agents build, raise PRs, review together. See what comes out the other side.

Does this exist? If not, an idea for someone with free time.
