Harness Design for Long-Running Application Development
Anthropic’s harness design write-up is the blueprint for how to push agents through multi-hour builds without babysitting them. I reference it because it explains why naive single-session coding falls short and how a structured harness makes long-running work tractable.
Pros
- +Clear engineering rationale for long-running agent harnesses
- +Helpful mental model for planning, iteration, and reliability
Cons
- -Doesn’t provide a ready-to-run open-source harness implementation
