📄 Documentation & Reference Models

This /docs folder contains Product Requirements Documents (PRD), data model definitions, and Firebase schema references for the Karaoke App project.

These files are intended for:

• 📃 Developers reviewing the business logic and architecture.
• 🤖 AI tools like Cursor or Copilot that reference documentation for context-aware coding.
• 📝 Project planning, architecture decisions, and future enhancements.
• 🚀 Building the app from scratch with any framework/platform combination.

🚀 How to Use This Documentation

For AI-Assisted Development:

Simply say "Read this PRD" in any new chat. The PRD contains:

• Self-guiding instructions for AI implementation
• Complete technical specifications for 100% accuracy
• Implementation questions to determine platform/framework choices
• Step-by-step build process with checklists

For Human Developers:

• Reference during implementation for business logic and data flows
• Guide for architecture decisions and technology choices
• Source of truth for all functional requirements
• Migration guide when switching frameworks/platforms

For New Implementations:

1. Read the PRD completely - it contains comprehensive specifications
2. Review design assets in design/ folder for visual reference
3. Answer implementation questions from Section 29
4. Follow the implementation checklist for complete build process
5. Preserve business logic while adapting UI to chosen framework

📋 Key Features of the Updated PRD

Platform-Agnostic Design:

• Core requirements separated from implementation details
• Framework-specific sections clearly marked
• Migration guidance for different platforms
• Toolset rationale for informed technology choices

Complete Technical Specifications:

• Data flow diagrams for all operations
• State management architecture with exact structure
• Service layer APIs with function signatures
• Component architecture with interfaces and behavior
• Error handling matrix for all scenarios
• Performance specifications with optimization patterns

Implementation Guide:

• 7 key questions to determine platform/framework
• 5-phase implementation checklist
• Must preserve vs. can replace guidelines
• Critical success factors for accurate builds

Design Assets:

• Visual mockups for all major features and screens
• Platform-specific designs (web, mobile, etc.)
• UX patterns and interaction flows
• Design system references for consistent implementation

🔄 Workflow for New Versions

When Creating New Implementations:

1. Use the PRD as-is - it's designed for any framework/platform
2. Reference design assets for visual guidance and UX patterns
3. Follow the implementation guide in Section 29
4. Preserve all business logic while adapting UI layer
5. Test against specifications for 100% accuracy

When Updating the PRD:

1. Keep platform-agnostic requirements intact
2. Add new implementation details to appropriate sections
3. Update toolset sections with new technology choices
4. Maintain self-guiding nature for AI implementation

When Migrating Platforms:

1. Keep all business logic from core requirements
2. Replace only implementation details in platform-specific sections
3. Add new platform sections following the established pattern
4. Update toolset rationale for new technology choices

Important Notes

• ✅ These files are not intended for direct import or use in application runtime.
• ✅ Validation logic and data models here serve as development references only.
• ✅ Any updates to business logic, data flow, or app architecture should be reflected here for documentation purposes.
• ✅ AI tools may use this information to assist with code generation but will not access /src directly.
• ✅ The PRD is self-guiding - it contains all instructions needed for AI implementation.
• ✅ 100% accuracy achievable when following the complete specifications.
