## Resource

Felix Rieseberg is the engineering lead for Claude Cowork and Claude Code Desktop at Anthropic. He previously spent five years at Slack building developer tools. In this episode, Felix demonstrates how he uses Claude to solve real-life problems: analyzing floor plans to build interactive 3D house walkthroughs, automatically tracking promises he makes on Twitter, and building a $20 hardware device that physically approves Claude actions with a button press. What you’ll learn: How to use Claude Cowork to turn a 2D floor plan into an interactive 3D walkthrough where you can move furniture around The “go one abstraction layer up” philosophy: why you should never manually enter data Claude can find itself How to use your email as an inventory database for furniture, clothing, and personal purchases When to use Opus vs. Sonnet 4.6 (hint: it’s about how well you can scope the problem, not technical complexity) How live artifacts work and why they’re powerful for dashboards that refresh with real-time data from your connectors The product philosophy behind making latency delightful How to build your own $20 hardware device using Claude Code (no hardware experience required) Why Felix never reads the code Claude writes and judges it purely on output — Brought to you by: Magic Patterns —Prototypes that look like your product Guru —The AI layer of truth — In this episode, we cover: (00:00) Introduction to Felix Rieseberg (02:40) Felix’s role at Anthropic (03:25) The multiple tabs in Claude and why they exist (05:55) Using Claude Cowork to design a new house using floor plans (09:52) When to use Opus versus Sonnet 4.6 (12:37) Building an interactive 3D furniture planner (14:30) Using your email as a source of truth for personal inventory (15:58) The anti-to-do list: going one abst…
