KnowAct-GUIClaw Reports 64.1% on MobileWorld, Beating GPT-5.5 and Seed-2.0-Pro With a Self-Evolving Skill Library

arXiv / HuggingFace Daily Papers·medium signal

A Know-Route-Act-Reflect GUI agent pairing an experience-attributable memory system (for task decomposition and long-horizon planning) with a pluggable, self-evolving skill library that migrates across platforms. It reports 64.1% on MobileWorld — ahead of closed-source Seed-2.0-Pro and GPT-5.5 — validated on Android, iOS, HarmonyOS, and Windows, with an 8.5% improvement when learned skills transfer to a different base model. That cross-model skill transfer number is the most interesting claim: it suggests learned GUI skills are somewhat model-portable assets rather than model-specific artifacts.
