QA: Open-Ended Generative UI — Claude Agent SDK (Python)

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy
• ANTHROPIC_API_KEY is set

Test Steps

1. Basic Functionality

• Navigate to /demos/open-gen-ui
• Verify the chat renders with minimal suggestions visible
• Click the "3D axis visualization (model airplane)" suggestion
• Verify a sandboxed iframe appears with the generated visualization

2. Feature-Specific Checks

• Verify the iframe contains SVG-based content (not div-stacks)
• Try the "Quicksort visualization" suggestion — verify an animated bar sort renders
• Verify the visualization is self-running (no user interaction needed)

3. Error Handling

• Verify no CORS/CSP errors in the console
• Verify the sandbox iframe renders within the chat turn

Expected Results

• Agent calls generateSandboxedUi once per turn
• The runtime's OpenGenerativeUIMiddleware converts the call into activity events
• The built-in renderer mounts the agent-authored HTML inside a sandbox
