build-ai-uis-workshop-app

Build a new workshop demo in this app from A2UI (declarative JSON UI) or MCP Apps (sandboxed iframe widgets). This is the right skill for ANY request to create a new demo, skill, or playground built from those protocols. Two targets: (1) a real chat skill that appears at /chat/@workshop-user/<slug> and emits A2UI or renders an MCP App widget live in the product chat (the default — needs a Gemini key), and (2) a no-key /dev fixture page for offline teaching. Use whenever the user wants to add, create, make, scaffold, or build a demo, chat skill, playground, A2UI surface, or MCP App widget — including "make me a demo/skill that does X", "add a skill that shows up in chat", "a form in chat from A2UI", "add an MCP App widget", or "new /dev playground". NOT for AG-UI, file-browser, or rich-media (already-built fixtures).
