Updated on 2026-10-08. Open Harness is now AGRO. This post uses the current names and commands.
To learn AGRO, watch a clean machine become an agent-ready development environment. The demo installs the sandbox, attaches an editor, and checks the agents. Then the demo connects GitHub, and an agent creates its first issue and pull request.
The full Loom walkthrough shows the full demo. This post turns the demo into a written runbook. The runbook also states the corrections: safe defaults, when not to mount Docker, the contents of .agro/, and how worktrees isolate agent work. The video and the screenshots record the July 2026 demo. The installer and the wizard screens changed after the demo.
