[About]
Rizel Scarlett is driven by a singular mission: ensuring powerful technology feels human, joyful, and real. As the Tech Lead for Open Source Developer Relations at Block, she drives technical storytelling for goose, an open source AI agent. Previously at GitHub, she helped developers understand and adopt GitHub Copilot, using storytelling to make AI and developer tools feel more approachable. Outside of work, she unwinds by watching reality TV, annoying her husband for fun, and navigating the chaos and joy of first-time motherhood.
The Last Website You'll Ever Visit (in the Browser)
When was the last time you visited Stack Overflow?
If you are like most developers, you are asking an AI agent first. This marks a fundamental shift. We are moving from a navigation based web, where you go to a site, to an intent based web, where the result comes to you.
For years, we tried to keep users inside our apps by stuffing chatbots into the corners of our pages. You know the one. “A girl in your area wants to chat with you” about cloud infrastructure, of course. These bots were meant to automate support and keep users on our URLs.
But users have moved on. They are staying inside AI agents to get things done. If the user will not go to your URL, your app has to go to them.
Join Rizel to learn about MCP-UI and MCP Apps, an open standard that allows developers to render fully interactive, bidirectional interfaces directly inside agents like goose. You will learn why the URL is becoming a tool call and how your React skills position you to build the mini apps that will define the agentic era.
