Google AI Introduces EnvHarness: A Programmable Layer That Turns Static Agent Environments Into Adaptive Training Worlds

Google Cloud AI Research, with Washington University in St. Louis and UNC Chapel Hill, released EnvHarness, an Apache-2.0 layer that turns static agent benchmarks into adaptive training environments by wrapping frozen environments through the standard reset()/step() interface. Its LLM designer, EnvRigger, automatically writes wrappers against flaws in the agent's rollouts, and across five benchmarks, mined skills gained up to 9.0 points on held-out tasks with 9.8% fewer execution steps.

Google Cloud AI Research, with Washington University in St. Louis and UNC Chapel Hill, has released EnvHarness, an Apache-2.0 layer that turns a static agent benchmark into one that adapts to the policy training on it. It wraps a frozen environment through the standard reset /step interface, so tasks and human-built verifiers stay untouched — and an LLM designer, EnvRigger, writes those wrappers automatically against flaws diagnosed in the agent's own rollouts. Across five benchmarks, mined skills gain up to 9.0 points on held-out tasks with 9.8% fewer execution steps.
