超越 Harness：为 AI 智能体构建有界画布
原标题：Presentation: Beyond the Harness: Canvas for AI Agents
AI 摘要
Thoughtworks 技术顾问 Nimisha Asthagiri 在 InfoQ 演讲中提出，AI 智能体工程正从「提示词工程」「上下文工程」演进到「harness 工程」，并建议将心智模型从受控的 harness 转向「有界画布」（bounded canvas），以管理智能体拓扑。她借用自身领导开源社区架构的经验，强调用架构决策记录等「痕迹」应对 AI 智能体带来的认知债务，并主张以演化式架构和混沌工程思路长期设计智能体系统。

Transcript Nimisha Asthagiri: Today, I'm going to talk about, "Beyond the Harness: Canvas for AI Agents." I want to start with a story. I don't know about you, but for me, it feels like deja vu. Why it is, is because many moons ago, I used to be heading up architecture for an open-source community. In that community, we had a codebase that had grown organically. We had to worry about decay of the codebase. There were feature toggles that were not being garbage collected. There was code that peop
