How to choose TypeScript and Node.js skills
Matteo Collina's Node.js and Fastify skills come from a Node.js core maintainer and cover type stripping, async patterns and server structure.
Pick typescript-magician or typescript-pro when generics and strictness are the hard part; both are Markdown guidance.
Framework quickstarts for LangChain, LangGraph and Genkit scaffold a project and need the matching model provider key.
