QA — byoc-hashbrown

Scope

Manual QA checklist for the byoc-hashbrown demo in the AWS Strands showcase. The agent emits a hashbrown JSON envelope that @hashbrownai/react progressively parses and renders via the MetricCard / PieChart / BarChart / DealCard / Markdown catalog.

Happy path

• Navigate to /demos/byoc-hashbrown.
• Page renders with header "BYOC: Hashbrown" and no console errors.
• Suggestion pills appear in the composer (Sales dashboard, Revenue by category, Expense trend).
• Click "Sales dashboard" — the assistant replies with a progressively streaming dashboard that includes at least one metric card, one pie chart, and one bar chart.
• Click "Revenue by category" — the assistant replies with a pie chart with 4+ segments.
• Click "Expense trend" — the assistant replies with a bar chart.

Regression

• The assistant's response is rendered as a visual dashboard (NOT as raw JSON in a chat bubble).
• data-testid="metric-card", data-testid="pie-chart", and data-testid="bar-chart" are present on their respective elements.
• No hydration warnings.

Known gaps

• The Strands backend uses the shared agent from agent.py; the hashbrown JSON envelope prompt is injected via useAgentContext on the frontend. The canonical prompt lives in src/agents/byoc_hashbrown.py as documentation.
