Thariq Shihipar is an engineer at Anthropic working on the Claude Code team. Hes spent the past several months experimenting with HTML as a replacement for Markdown in planning and implementation workflows, discovering that richer visual formats lead to better human engagementand, ultimately, better products. In this episode, filmed at Anthropics Code with Claude event in San Francisco, Thariq demonstrates how to use HTML artifacts to create interactive plans, build throwaway UIs for specific problems, and maintain living design systems that travel with your codebase.Listen or watch on YouTube, Spotify, or Apple PodcastsWhat youll learn:Why HTML has replaced Markdown as the ideal format for AI agent communication and planningHow to brainstorm in HTML to get visual mockups and interactive demos instead of text listsThe technique for building throwaway micro-UIs to edit specific parts of your planHow to create a living design system in HTML that lives in your repo and travels with every projectWhy complexity has to earn its keep and how HTML helps you stay in the loop without over-constraining ClaudeThe prompting technique that gives Claude flexibility while ensuring that you get what you needWhy 99% of your AI-generated tokens should go to planning, interfaces, and communicationnot production codeBrought to you by:CeligoIntelligent automation built for AIPersonaTrusted identity verification for any use caseIn this episode, we cover:(00:00) Introduction(02:39) HTML as the new Markdown(04:30) The compute allocator mindset(05:51) How HTML makes specs more engaging(06:48) Demo: Brainstorming in HTML with Claude Code(09:24) From brainstorm to full implementation plan(11:20) Prompting philosophy: Trust Claude but give it constraints(13:50) The future of PRDs and tech specs(18:16) Making HTML specs editable(20:23) The abundance mindset(24:17) Just-in-time documentation and throwaway software(25:39) Using plans as artifacts for implementation(26:39) Demo: Living design systems in HTML(30:16) Adding comments and annotations to HTML plans(31:42) Recap: The HTML workflow(32:21) Lightning round and final thoughtsTools referenced: Claude Code: https://claude.ai/code Claude Design: https://claude.ai/design AWS: https://aws.amazon.com/ Figma: https://www.figma.com/ GitHub: https://github.com/Other references: Anthropic Code with Claude event: https://claude.com/code-with-claude SpaceX partnership announcement: https://www.anthropic.com/news/higher-limits-spacex Jevons paradox: https://en.wikipedia.org/wiki/Jevons_paradoxWhere to find Thariq Shihipar:Website: https://www.thariq.io/LinkedIn: https://www.linkedin.com/in/thariqshihipar/X: https://x.com/trq212GitHub: https://github.com/ThariqSWhere to find Claire Vo:ChatPRD: https://www.chatprd.ai/Website: https://clairevo.com/LinkedIn: https://www.linkedin.com/in/clairevo/X: https://x.com/clairevoProduction and marketing by https://penname.co/.
