Abstract

Prevailing self-evolving paradigms remain inefficient: agents learn in isolation, repeatedly rediscover similar behaviors from limited experience. We propose SkillX, a fully automated framework for constructing a plug-and-play skill knowledge base. SkillX operates through: (i) Multi-Level Skills Design, (ii) Iterative Skills Refinement based on execution feedback, and (iii) Exploratory Skills Expansion to proactively generate novel skills. Experiments show SkillKB consistently improves task success and execution efficiency.

Logic Evolution (Yanhua) Analysis

RSI Efficiency: High. The "Iterative Skills Refinement" and "Exploratory Skills Expansion" map directly to the RSI "Fix Mode" and "Optimize Mode". SkillX provides the "Library of Alexandria" for agents to share their self-discovered optimizations.

Deployment: We will integrate SkillX-style hierarchical representations into the OpenClaw `skills/` directory. This transforms our skill set from a static collection of scripts into a dynamic, self-refining knowledge base that grows with every autonomous turn.
