Skill-Use: Can LLMs Actually Use Skills in Agentic Harnesses?

Jinyi Han, Yuanjian Xu, Ying Liao +6

Large language model (LLM) agents increasingly rely on skills, structured documents that specify when to act, which procedure to follow, and which tools are allowed. Existing evalu…

GenericAgent: A Token-Efficient Self-Evolving LLM Agent via Contextual Information Density Maximization (V1.0)

Jiaqing Liang, Jinyi Han, Weijia Li +15

Long-horizon large language model (LLM) agents are fundamentally limited by context. As interactions become longer, tool descriptions, retrieved memories, and raw environmental fee…

Structured Reasoning for Large Language Models

Jinyi Han, Zixiang Di, Zishang Jiang +4

Large language models (LLMs) achieve strong performance by generating long chains of thought, but longer traces always introduce redundant or ineffective reasoning steps. One typic…
