 Open it via **Web Preview** (the <walkthrough-spotlight-pointer spotlightId="devshell-web-preview-button">Web Preview button</walkthrough-spotlight-pointer> in the Cloud Shell toolbar → *Preview on port 8000*), and select **cymbal_concierge**.

+1. **Analytical** — ask: ``What was our total revenue in the last 30 days?``
    Watch the event trace in the UI: concierge → *A2A call to cymbal_analyst on :8001* → Conversational Analytics API → SQL on `cymbal_gold`. Four systems, one question.
 2. **Operational** — ask: ``What's the status of order 421337?``
