Beyond Top-k Skill Retrieval: Diversity-Aware Skill Routing for LLM Agents
The paper proposes routing LLM agents toward skill sets that are complementary, not just individually relevant.
DSR reranks candidate skills with a Determinantal Point Process to reduce redundant selections. Its query-residual diversity kernel is meant to avoid penalizing overlap that comes only from shared relevance to the user request. On the SkillRouter benchmark, the authors report better recall and full coverage than a strong pointwise reranking baseline, especially for multi-skill queries. HF Daily Papers' note
