Google explains harness engineering: building deterministic guardrails so coding agents can self-repair

什么是 harness 工程？Google 用 ADK 2.0 与 Antigravity SDK 演示自动修复编码循环

Shir Meir Lador from Google AI breaks down harness engineering: wrapping a coding agent in deterministic guardrails—sandboxing, repair loops, and progressive context discovery—so it can self-correct. She cites an OpenAI experiment where 3 engineers shipped an internal beta with zero manually-written lines, and shows a code snippet using Google ADK 2.0 and Antigravity SDK to bound the agent to a workspace and persist its trajectory memory.
