SkillFlow: Scalable and Efficient Agent Skill Retrieval System
Quick summary
arXiv:2504.06188v3 Announce Type: replace Abstract: AI agents can extend their capabilities at inference time by loading reusable skills into context, yet equipping an agent with too many skills, particularly irrelevant ones, degrades performance. As community-driven skill repositories grow, agents need a way to selectively retrieve only the most relevant skills from a large library. We present SkillFlow, the first open, multi-stage retrieval system for agent skill discovery that frames skill acquisition as an information retrieval problem over a corpus of ~35K community-contributed SKILL.md d

Why it matters
This is more than a company headline: it shows who controls infrastructure, users and data in the AI value chain. The practical effect will appear in product integration, pricing and delivered capacity.
