SummaryStructAgent is a state-centered framework for long-horizon digital agents that uses a unified causal representation of task progress, with verifier-backed state transitions, explicit checkpointing, and failure recovery. It improves Qwen3.5 backbones substantially on OSWorld-Verified and sets a new open-source SOTA of 78.9%, also generalizing to Minecraft.
Why it mattersConcrete framework tackling a real bottleneck in long-horizon agents — unstructured interaction history. The causal-state design and cross-domain results (desktop + Minecraft) make it directly applicable to agent builders.
