The documentation here is pretty sparse, so you're flying a bit blind with this one. Based on the name, it's likely meant to route decisions or tasks through some kind of expert selection pattern, common in agentic workflows where you want specialized handling for different domains. With 243 installs and part of a Next.js 16 agent skills collection, it seems people are trying it out despite the lack of SKILL.md. If you're building multi-agent systems or need dynamic expert routing in your Next.js app, it might be worth exploring the source code directly on GitHub to see what's actually under the hood before adding it to your project.
