Harness-of-Harness: Multi-Day Autonomous Software Development with Continual Improvement
Harness-of-Harness addresses a real bottleneck: agents that code tend to diverge in capability across iterations. The trick is separating test-during-development from independent evaluation, scoping increments, and maintaining version history. For teams using agents for software development, this is the operational model that works—small verifiable steps, not big swings.
