EnvHarness Framework Dynamically Adapts Static Worlds for Agent Learning
shangbinfeng · x · 2026-08-22
EnvHarness introduces a unified wrapper framework to address the limitations of static environments in LLM Agent training. By enabling non-intrusive interception and dynamic adaptation without modifying underlying logic, it unlocks richer training signals. The framework includes EnvRigger, an automated tool that synthesizes components based on agent execution traces to target diagnosed flaws. Experiments across five benchmarks in four domains show that EnvHarness outperforms both original environments and domain-specific generation pipelines, achieving up to a 9.0-point improvement with 9.8% fewer execution steps.
