REVERSE-ENGINEERING CLAUDE'S GENERATIVE UI - THEN BUILDING IT FOR THE TERMINAL

Summary from the TLDR AI newsletter

Claude's generative UI is a tool call that returns HTML injected into the DOM with incremental parsing as tokens stream. It enables interactive widgets to be rendered inline in Claude conversations. It uses lazy-loading documentation to insert context on demand. The terminal spawns Glimpse windows with bidirectional JSON communication, allowing the terminal to stay as a terminal while the visual content gets a real browser engine.
