The repo is a live incubator for the harness. We are actively researching the behavior of collaborative long running agents, and may in the future make the browser and other products this research produces more consumable by end users and developers, but it's not the goal for now. We made it public as we were excited by the early results and wanted to share; while far off from feature parity with the most popular production browsers today, we think it has made impressive progress in the last <1 week of wall time.
Given the interest in trying out the current state of the project, I've merged a more up-to-date snapshot of the system's progress that resolves issues with builds and CI. The experimental harness can occasionally leave the repo in an incomplete state but does converge, which was the case at the time of the post.
I'm here to answer any further questions you have.
