   STEP 3 - REVIEW CODE (based on Flutter AI rules + Context7 docs)
-  ═══════════════════════════════════════════════════════════════
+  ===============================================================
 
-  DART BEST PRACTICES (from official Flutter rules):
+  Apply best practices from Context7 documentation:
+
+  DART BEST PRACTICES:
   - Follow Effective Dart guidelines (https://dart.dev/effective-dart)
   - Proper null safety - avoid ! unless value is guaranteed non-null
   - Use async/await correctly with robust error handling
   - Pattern matching and records where they simplify code
-  - Exhaustive switch statements (no break needed)
   - Arrow syntax for simple one-line functions
-  - Use try-catch with appropriate exception types
   - PascalCase for classes, camelCase for members, snake_case for files
-  - Line length 80 characters or fewer
-  - Functions under 20 lines with single purpose
 
-  FLUTTER BEST PRACTICES (from official Flutter rules):
+  FLUTTER BEST PRACTICES:
   - Widgets (especially StatelessWidget) are immutable
   - Composition over inheritance - compose smaller widgets
   - Use const constructors whenever possible to reduce rebuilds
   - Break down large build() methods into smaller private Widget classes
-  - Use small, private Widget classes instead of helper methods returning Widget
   - Use ListView.builder or SliverList for long lists (lazy loading)
-  - Use compute() for expensive calculations in separate isolate
-  - Avoid expensive operations (network, complex computations) in build() methods
-  - Use logging package instead of print
+  - Avoid expensive operations in build() methods
 
   STATE MANAGEMENT (verify against Context7 docs):
   - Prefer Flutter built-in: ValueNotifier, ChangeNotifier, Streams
   - If using BLoC/Cubit - verify proper event/state separation
   - If using Riverpod - verify proper provider usage and disposal
-  - If using Provider - verify ChangeNotifier usage
-  - Separate ephemeral state from app state
   - Proper dispose/close of controllers and streams
-  - Use MVVM pattern for robust solutions
-
-  ARCHITECTURE (from official Flutter rules):
-  - Separation of concerns (MVC/MVVM)
-  - Logical layers: Presentation, Domain, Data, Core
-  - Feature-based organization for larger projects
-  - Repository pattern for data abstraction
-  - Manual constructor dependency injection
-
-  CODE QUALITY:
-  - Meaningful, consistent naming (no abbreviations)
-  - Documentation comments (///) for all public APIs
-  - Clear comments for complex/non-obvious code
-  - Don't repeat information obvious from code context
-  - API documentation should be user-centric
-
-  UI/THEMING (from official Flutter rules):
-  - Centralized ThemeData object
-  - Light and dark theme support (ThemeMode.light, .dark, .system)
-  - Use ColorScheme.fromSeed() for harmonious color palettes
-  - Responsive layouts with LayoutBuilder or MediaQuery
-  - Use Theme.of(context).textTheme for text styles
-  - Custom fonts via google_fonts package
-  - Network images: always include loadingBuilder and errorBuilder
-
-  ACCESSIBILITY (from official Flutter rules):
-  - Color contrast ratio at least 4.5:1 for text
-  - Test with increased system font size
-  - Use Semantics widget for clear labels
-  - Test with TalkBack (Android) and VoiceOver (iOS)
-
-  LIBRARY-SPECIFIC CHECKS:
-  - Verify correct API usage based on Context7 documentation
-  - Check for deprecated methods or patterns
-  - Ensure best practices for each library are followed
-  - Check version compatibility
 
   SECURITY:
-  - Sensitive data handling
   - API key exposure check (no hardcoded keys)
   - Secure storage usage (flutter_secure_storage)
   - Input validation
   - HTTPS for network requests
 
-  TESTING (from official Flutter rules):
-  - Unit tests for domain logic, data layer, state management
-  - Widget tests for UI components
-  - Integration tests for end-to-end flows
-  - Arrange-Act-Assert (Given-When-Then) pattern
-  - Prefer fakes/stubs over mocks
-  - Use package:checks for readable assertions

-prompt: |
-  Review the code in this Flutter repository.
-
-  IMPORTANT: Use shell commands (via developer extension) to read files. Do NOT use filesystem extension.
-
-  STEPS:
-
-  1. FETCH FLUTTER RULES (run shell command):
-     ```bash
-     curl -sL "https://raw.githubusercontent.com/flutter/flutter/refs/heads/main/docs/rules/rules.md"
-     ```
-
-  2. FETCH CONTEXT7 DOCS:
-     Use Context7 MCP tools to get documentation for Flutter and Dart:
-     - Call resolve-library-id with query "flutter"
-     - Call get-library-docs for the Flutter library
-     - Call resolve-library-id with query "dart"
-     - Call get-library-docs for Dart
-
-  3. ANALYZE DEPENDENCIES (run shell commands):
-     ```bash
-     cat pubspec.yaml
-     ```
-     For each major dependency (bloc, riverpod, dio, etc.), fetch Context7 docs.
-
-  4. GET DIFF (run shell command):
-     ```bash
-     git diff origin/main...HEAD
-     ```
-
-  5. REVIEW each changed file against:
-     - Official Flutter AI rules
-     - Context7 documentation for each library used
-
-  Remember: READ-ONLY mode - do not modify any files.

+
+  ===============================================================
+  STEP 3 - REVIEW CODE
+  ===============================================================
+
+  Apply best practices from Context7 documentation:
+
+  JAVASCRIPT/TYPESCRIPT FUNDAMENTALS:
+  - Proper use of const/let (avoid var completely)
+  - Strict equality (=== instead of ==)
+  - Proper TypeScript types (avoid any, use unknown when type is truly unknown)
+  - Null/undefined handling (optional chaining ?., nullish coalescing ??)
+  - Proper async/await with try-catch error handling
+  - No floating promises (always await or handle with .catch())
+
+  REACT BEST PRACTICES:
+  - Functional components with hooks (not class components)
+  - Proper hook usage (Rules of Hooks - don't call in loops/conditions)
+  - useMemo for expensive calculations
+  - useCallback for stable function references passed to children
+  - Key props on list items (never use index as key for dynamic lists)
+  - useEffect dependency arrays (include ALL dependencies)
+  - Cleanup in useEffect return functions (timers, subscriptions)
+
+  NEXT.JS BEST PRACTICES (if applicable):
+  - Proper use of Server Components vs Client Components
+  - 'use client' directive only when necessary
+  - Correct data fetching patterns (Server Actions, fetch with caching)
+  - Image optimization with next/image
+
+  SECURITY (always check):
+  - No hardcoded secrets/API keys (use env vars)
+  - XSS prevention (avoid dangerouslySetInnerHTML, sanitize user input)
+  - Input validation (zod, yup, or manual)
+  - Dependency vulnerabilities (check npm audit)
