Think about it, you're running a third-party UI (Shopify, Notion, etc.) inside your AI chat. Which could be dangerous but the solution is Sandbox iframes; it lets devs run third-party UI components securely. As it runs isolated with no access to host’s origin, host’s cookies,

This is how the whole flow works around the architecture: When a user asks a question to Claude: “Show me eco-friendly phone cases with fast shipping” Claude triggers a tool call to @Shopify. Shopify’s Server SDK (library to create & send UI resources) creates a URL resource.

My 2025 developer hiring hot takes: 1. Leetcodes in 2025 is the "how many golf balls fit in a 747" of the 1990s. 2. Companies banning AI in interviews while >50% of their code being written by AI is funny. 3. One 100x engineer > ten 10x engineers. But finding them takes 10x
