I'd be happy to help you build a prototype! However, I don't see a PRD (Product Requirements Document) attached to your message.

To create an effective plan and build the right prototype, I need to see the PRD first. Could you please:

1. Share the PRD - Either paste it in the chat or attach it as a file

2. Clarify the scope - Once I see the PRD, I'll need to understand:

   • Is this client-only, client+server, or full stack with database?
   • Are there any existing components/systems I should integrate with?
   • What's the primary goal of this prototype (proof of concept, user testing, demo, etc.)?

Once I have the PRD, here's my general approach:

My Planning Process

1. Analyze the PRD - Extract user stories, technical requirements, and phases
2. Define data model - Identify entities and relationships
3. Create component architecture - Plan reusable component library
4. Design system analysis - Define colors, typography, spacing, layout patterns
5. Implementation phases - Break into small, manageable batches
6. State management strategy - Plan centralized state (likely React Query + Context)

Tech Stack (Based on Your Preferences)

• Framework: React + Vite
• Styling: Tailwind CSS
• Routing: React Router (if multipage)
• State Management: React Query + Context API
• Charts: Recharts (if data visualization needed)

Could you please share the PRD so I can create a detailed implementation plan?

Thank you for sharing this comprehensive PRD! I can see this is for an AI-Personalised AR Safety Guidance app targeting older homeowners like Lorena. The concept is excellent - using AR to help detect home hazards in real-time with customizable alerts.

My Plan & Clarifying Questions

Before I start building, I need to clarify a few key points since this is inherently a mobile AR application but you've requested React + Tailwind:

Scope Questions:

1. Platform Approach: Since true AR requires native mobile capabilities (ARKit/ARCore), should I build:

   • A web-based prototype that simulates the AR experience with overlays on camera feed?
   • A React Native app (though you specified React + Tailwind)?
   • A responsive web app that demonstrates the UI flows and settings, with mocked AR detection?

2. Core Features for V0: Which features should I prioritize for this prototype?

   • Onboarding flow + settings configuration?
   • Simulated live detection screen with mock hazard overlays?
   • History view and feedback system?
   • All of the above?

3. Data & State: Should I:

   • Use mock data for hazard detection results?
   • Implement the settings persistence (sensitivity, notification style)?
   • Create a simple state management system for user preferences?

My Proposed Approach:

I'm thinking of building a responsive web prototype that demonstrates:

1. Onboarding flow - camera permissions, initial setup
2. Settings panel - sensitivity slider, notification toggles, privacy mode
3. Simulated detection screen - camera view with mock AR overlays
4. History view - past hazard log
5. Feedback system - hazard confirmation buttons

This would let us test the UX flows and visual design before moving to native AR implementation.

Does this approach align with your vision? Which features should I focus on first?
