QA: In-App HITL — Claude Agent SDK (Python)

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy (check /api/health)
• ANTHROPIC_API_KEY is set

Test Steps

1. Basic Functionality

• Navigate to /demos/hitl-in-app
• Verify the Support Inbox renders three tickets (#12345, #12346, #12347)
• Verify the chat surface renders on the right

2. Approval Flow

• Click the "Approve refund for #12345" suggestion
• Verify a modal dialog appears with the action summary
• Click "Approve" — verify the dialog closes and the agent confirms

3. Rejection Flow

• Click the "Downgrade plan for #12346" suggestion
• Verify the modal appears
• Add a note "Customer needs to stay on current plan"
• Click "Reject" — verify the agent acknowledges the rejection

4. Error Handling

• Verify no console errors during the approval/rejection flows
• Verify the modal blocks interaction with the chat until resolved

Expected Results

• Modal uses fixed inset-0 overlay rather than a portal (to avoid @types/react-dom)
• Agent accurately reflects the approve/reject outcome
