HTML is the new Markdown: How Anthropic engineers are building with Claude Code | Thariq Shihipar

Markdown became a really popular way of interacting with agents, but the plans are so long. I honestly have stopped reading them. And this is honestly a mistake. I think that you still need to be really in the loop. Plans matter. PRDs matter. Spec matters. When you say, okay, Claude can run for eight hours, what you're really saying is Claude can spend $500. All of us are becoming these compute allocators now. Right? And so you have to decide what is worthwhile spending the compute on. People ask me all the time, Claire, you said product management is dead. What's next? And I'm gonna say, you're a compute allocator, babe. That's the job now. HTML is a lot easier to read, and so it's just a richer communication medium between you and Claude. Instead of saying, here's a markdown document, it was like, what's the best way to convey this information? So you can actually engage with it and pick something. This is the plan. It's purely an HTML. This is something that I will actually read. This is not even personal software. It's like micro software, on top of micro software. Welcome back to How I AI. I'm Claire Vaux, product leader and AI obsessive here on a mission to help you build better with these new tools. Recently, I was able to attend Code with Claude, Anproppet's first developer conference. And as part of that, I got to spend a little time with Tarek, who works on Claude code and taught me something that has blown my mind ever since I heard it. HTML is the new markdown. He's gonna show us how to use cloud code to generate rich artifacts that both you and the agents can enjoy working on. Let's get to it. This episode is brought to you by Soligo. Every company today wants AI to improve how work gets done. The fastest way is building it directly into everyday business processes, automating employee onboarding, keeping customer data accurate, managing orders and inventory, or resolving finance and operations issues. When AI lives inside the flow of work, it can update records, trigger approvals, route work, and kick off the next step across systems. That's how teams operationalize AI and deliver measurable results. Seligo makes this possible. And now with Seligo Aura, it's never been easier. Seligo Aura gives you access to the entire platform through natural language, connecting your systems and turning intent into action. All of it under your control. Companies like Databricks, PayPal, and Olipop rely on Celigo to run critical business operations at scale. Ready to operationalize AI? Visit celigo.com/howiai. That's celigo.com/howiai. Welcome to howiai. Thanks for having me. I am so excited to be here at Code with Claude in San Francisco. There's a lot of exciting things that were announced, and we'll get to that in a little bit. But you told me something I was not expecting to hear today, which is you heard it here first. …
