How the engineer behind Claude Cowork actually uses Claude | Felix Rieseberg (Anthropic)

Anthropic's engineering lead Felix Rieseberg demonstrated how he uses Claude to solve real-life problems in a recent episode. Rieseberg, who previously spent five years building developer tools at Slack, showed attendees how to use Claude Cowork to create interactive 3D house walkthroughs from floor plans and build a $20 hardware device that physically approves Claude actions with a button press.

The episode covered various topics, including using email as an inventory database for personal purchases, understanding the philosophy behind making latency delightful, and building personal dashboards with live data. Rieseberg emphasized the importance of not manually entering data that Claude can find itself, advocating for the "go one abstraction layer up" approach. He also shared insights on how to use Opus versus Sonnet 4.6 and discussed the benefits of using live artifacts in Claude Cowork.

Claude is a platform that allows users to build custom tools and applications with AI, and Rieseberg demonstrated its capabilities by showcasing various examples, including designing interactive 3D furniture planners and building personal dashboards with real-time data from connectors such as Spotify and Gmail. The episode highlighted the potential of AI to free up creative energy and enable users to focus on high-level thinking rather than manual tasks.

Key tools referenced in the episode include Claude Cowork, Claude Code, Claude for Chrome, and live artifacts, among others.
