Researchers have developed SkillDuet, a framework designed to enhance reinforcement learning by co-evolving large language models (LLMs) and their associated skills. This system integrates parameter updates with the evolution of reusable textual skills, allowing skills to guide model interactions and subsequent updates. SkillDuet demonstrated strong performance, achieving 98.57% success on ALFWorld and 92.97% on WebShop with the Qwen3-4B model, outperforming the SEED-API baseline. The framework's effectiveness relies on response-based skill selection and consolidation into a persistent global skill set, highlighting the importance of skill content and model compatibility for recursive self-improvement.
