Phases to Execute

🔵 INCEPTION PHASE

• Workspace Detection (COMPLETED)
• Reverse Engineering (SKIPPED) - Greenfield project
• Requirements Analysis (COMPLETED)
• User Stories (SKIPPED) - Simple game with clear requirements
• Workflow Planning (IN PROGRESS)
• Application Design - EXECUTE
  • Rationale: New game components need design (game engine, rendering, input handling, state management)
• Units Generation - EXECUTE
  • Rationale: Game needs decomposition into logical units (core engine, UI, game logic)

🟢 CONSTRUCTION PHASE

• Functional Design - EXECUTE
  • Rationale: Game mechanics and business rules need detailed design
• NFR Requirements - EXECUTE
  • Rationale: Web security, performance, and extensibility requirements need assessment
• NFR Design - EXECUTE
  • Rationale: Security patterns and performance optimizations need design
• Infrastructure Design - SKIP
  • Rationale: Web-only application, no infrastructure changes needed
• Code Generation - EXECUTE (ALWAYS)
  • Rationale: Code implementation needed for the game
• Build and Test - EXECUTE (ALWAYS)
  • Rationale: Build, test, and verification needed

🟡 OPERATIONS PHASE

• Operations - PLACEHOLDER
  • Rationale: Future deployment and monitoring workflows

Package Change Sequence

N/A - Greenfield project, no existing packages

Estimated Timeline

• Total Phases to Execute: 7
• Estimated Duration: Moderate (game development with multiple components)

Success Criteria

• Primary Goal: Working Nokia Snake game in web browser
• Key Deliverables:
  1. Game engine with core mechanics
  2. Modern minimalist UI
  3. Full-featured game with power-ups and high scores
  4. Extensible codebase for future enhancements
  5. Security compliance (SECURITY baseline)
• Quality Gates:

  2. All core Snake mechanics implemented
  3. Code follows extensible framework patterns
  4. Security rules enforced where applicable
  5. High scores persist between sessions

Security Considerations

• SECURITY baseline enforced: Yes (user opted in)
• Key security areas: Web security headers, input validation, secure coding practices
• Compliance requirements: All applicable SECURITY rules must be followed
