SkillCome: Group Contrast Skill Optimization with Dual Memory

SkillCome introduces a skill-evolution framework that uses group contrast optimization and a dual memory system to refine large language model skills. By generating multiple trajectories per question and contrasting successful versus failed ones, it identifies key behavioral divergences to guide skill edits. The dual memory accumulates historical evidence across groups, enabling more generalized and reliable optimization signals, leading to consistent performance gains on diverse benchmarks.

SkillSpec: Consensus-Gated Agent Skill Evolution via Representation Specialization

SkillSpec is a two‑phase framework for evolving natural‑language skills in large language model agents. The first phase, consensus‑gated evolution, generates candidate skills from complementary editing intents and commits updates only when paired evaluations reach consensus on overall improvement and non‑negative aggregate gain. The second phase, representation specialization, uses signals from the optimization trajectory to choose an appropriate flat, graph, or hybrid structure for the skill, improving success rates by an average of 6.89% over SkillOpt across six benchmarks and three target language models.

SKILL-KD: Contrastive Skill Distillation for LLM Agents

arXiv:2607. 28048v2 Announce Type: replace Abstract: Skill-based prompting has become a practical mechanism for improving large language model (LLM) agents, yet existing skill acquisition methods often treat skills as experience summaries, memory entries, or direct summaries of successful demonstrations.
