QA: Headless Chat (Complete) — 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/headless-complete
• Verify the custom chat surface renders (header, scrollable list, input bar)
• Verify NO <CopilotChat /> imports are visible (all chrome is custom)
• Send "Hello" — verify the user bubble + assistant bubble render

2. Generative UI Weave

• Click the "Weather in Tokyo" suggestion — verify the WeatherCard renders inline
• Click the "Highlight a note" suggestion — verify the HighlightNote component renders
• Try a message that triggers other tools — verify the catch-all tool card renders

3. Lifecycle

• During agent response, verify the Send button swaps to Stop
• Click Stop — verify the agent cancels cleanly
• Verify no console errors after stop

Expected Results

• Messages area with data-testid="headless-complete-messages" scrolls automatically
• Input disabled while running; Send button disabled when empty
