Google Research: EnvHarness Automates Environment Evolution for Agents
omarsar0 · x · 2026-08-21
Google released research addressing the issue of static, hand-built training environments for agents that fail to scale with agent improvements. EnvHarness wraps static environments in a programmable layer to reshape behavior without modifying underlying logic. EnvRigger analyzes execution trajectories to synthesize components that diagnose and fix agent flaws. Across five benchmarks in four domains, the method achieved up to 9.0 points better performance on held-out instances with 9.8% fewer execution steps.
