QA: Open Generative UI (Minimal) — PydanticAI

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy (check /api/health)
• OPENAI_API_KEY set so the PydanticAI agent can reach gpt-4.1

Test Steps

1. Basic Functionality

• Navigate to /demos/open-gen-ui
• Verify the chat interface loads and suggestion pills render

2. Sandboxed UI Generation

• Click the "How a neural network works" suggestion
• Verify the agent streams an HTML/CSS payload and a sandboxed iframe mounts with the generated visualisation
• Verify the visualisation animates on its own (no host-side calls needed)
• Try at least one more suggestion (e.g. "Quicksort visualization") and verify each renders its own iframe

3. Error Handling

• Verify no console errors during normal usage
• Verify the iframe is sandboxed (check element in DevTools)

Expected Results

• Runtime openGenerativeUI flag streams generateSandboxedUi tool calls
• Each response produces a new sandboxed iframe with the agent-authored scene
• Scenes loop / auto-advance without needing host functions
