Adding a new content type to my blog-to-newsletter tool

This article describes how Simon Willison extended his blog-to-newsletter tool to incorporate a new content type called 'beats'—external content such as open source releases, new tools, and museum visits. He used a concise prompt with Claude Code to clone his blog repository for reference and modify the HTML/JavaScript tool to include beats with descriptions, similar to the Atom feed. The prompt effectively guided the AI to update the newsletter generation process, demonstrating a practical application of AI-assisted coding for IT/technology projects.
