  "text": "Cool paper on Skill routing for LLM agents.\n\nReal tasks rarely map to a single skill. They need several composed together, but most skill routing still treats the problem as picking one tool from a library.\n\nThis work formalizes Compositional Skill Routing, decomposes a complex query into atomic sub-tasks, retrieves the right skill for each, and then composes an executable plan.\n\nThe system, SkillWeaver, pairs an LLM decomposer with a bi-encoder FAISS retriever and a dependency-aware DAG planner.\n\nIt comes with CompSkillBench, 300 compositional queries over 2,209 real skills, so the multi-skill case gets measured directly.\n\nWhy does it matter?\n\nAs skill libraries grow, single-skill retrieval quietly caps what an agent can do. The DAG planner turns retrieved skills into an ordered, dependency-respecting plan.\n\nPaper: https://t.co/OvyScHiis1\n\nLearn to build effective AI agents in our academy: https://t.co/1e8RZKs4uX",
