# QA: Agentic Chat — LangGraph (Python) The minimum-viable CopilotChat demo: vanilla `` wired to a neutral helpful-assistant agent, with three starter-prompt suggestions. No tools, no custom rendering — anything richer belongs in dedicated demos (frontend-tools, tool-rendering, hitl-in-chat, etc.). ## Prerequisites - Demo is deployed and accessible - Agent backend is healthy (check `/api/health`) ## Test Steps ### 1. Initial render - [ ] Navigate to `/demos/agentic-chat` - [ ] Verify the chat input renders with placeholder "Type a message..." - [ ] Verify all three suggestion pills are visible: - "Write a sonnet" - "Tell me a joke" - "Is 17 prime?" ### 2. Free-form chat - [ ] Type a basic message (e.g. "Say hello") and press Enter - [ ] Verify the assistant streams back a text response ### 3. Suggestion pills - [ ] Click the "Tell me a joke" pill - [ ] Verify the message is sent and the assistant streams back a joke ### 4. Multi-turn context - [ ] Send "My name is Alice." - [ ] Wait for the assistant response - [ ] Send "What name did I just give you?" - [ ] Verify the assistant's second response contains "Alice" ### 5. Hygiene - [ ] No console errors during normal usage - [ ] No layout breakage with a very long input ## Expected Results - Chat input mounts within ~3 seconds - Assistant first-token latency is under ~5 seconds for short prompts; full responses complete within ~30 seconds - Suggestion pills render alongside an empty chat and disappear once a conversation is in progress
