It depends on what you mean by "unsupervised" - I've been strictly working through the agent, through specs the entire time, but it's been very supervised, I just leave the mistakes in-place and have it work from there.

However at this point it can completely maintain itself. When a new version of Claude or OpenCode is released, it updates itself to work on the latest version. It can also add new implementations for harnesses pretty reliably. It's actually pretty fun to watch it at this point. "Make this work on Hermes agent and message me when you're done" and an hour later or so, I can go play with it in Hermes.
