🎙 Paolo Ricciuti - on TypeScript MCP, AI, and the Craft of Software Development

Описание: Podcast page 👉 https://www.js-craft.io/blog/paolo-ri...

I interviewed Paolo Ricciuti, a software developer from Italy. Paolo is a core contributor to Svelte.js and also a maintainer of the TypeScript MCP library. We touched on many things, but a really interesting topic is what the Svelte team is doing with its MCP server to upgrade code to new versions. Instead of putting the code as training data, they are passing the rules to the LLM on how to upgrade the code.
