Runway

Orbit wraps agent runs in bounded execution cycles: one task selected from a dependency-ordered backlog, real test and lint gates that must pass before the task closes, and a structured artifact trail left after every run. You get four output files — agent result, rubric evaluation, a human-readable progress log, and an accept/iterate/stop recommendation — so you can audit what happened instead of re-running it from memory. The deterministic replay demo runs without an API key, which means you can inspect the full loop before wiring in Claude, Codex, or any other JSON-speaking CLI. The tool is intentionally scoped: it handles the harness, not the agent. Teams that need the agent itself to do more will hit that boundary fast.
