- Change from fail-fast to collect-and-continue at component iteration level
- Previously: first component error would halt processing of remaining components
- Now: all components are processed, errors collected and returned together
- Maintain existing collect-and-continue behavior within individual components
- Add comprehensive tests validating the collect-and-continue behavior works correctly
- All valid properties are applied even when invalid ones fail
- Processing continues through exceptions with proper error aggregation

Performance & Quality Improvements:
- Add shared JsonSerializer to eliminate per-call allocation overhead
- Optimize ComponentResolver with CacheByName for short-name lookups
- Deduplicate Vector3 parsing implementations to reduce maintenance burden
- Improve property name normalization for better fuzzy matching quality
- Reduce log noise by avoiding duplicate component resolution warnings
Code Quality:
- Keep using static import for ComponentResolver (CodeRabbit was incorrect about this)
- Normalize property names consistently in AI suggestions algorithm
- Remove duplicate ParseVector3 implementation
TestAsmdef Fix:
- Revert TestAsmdef back to runtime-compatible (remove "includePlatforms": ["Editor"])
- CustomComponent now works correctly for asmdef testing as originally intended
- Validates that ComponentResolver properly handles both short and FQN for asmdef components
Live Testing Validation:
- All ComponentResolver functionality verified through live MCP connection
- AI property matching working perfectly with natural language input
- Assembly definition support fully functional for both default and custom assemblies
- Error handling provides helpful suggestions and complete context
All 45 C# tests + 31 Python tests still passing. Production ready!

Critical Bug Fixes:
- Fix operator precedence bug in ManageAsset.cs that could cause null reference exceptions
- Fix GameObject memory leak in primitive creation when name validation fails
- Add proper cleanup with DestroyImmediate when primitive creation fails
ComponentResolver Integration:
- Replace fragile string-based GetComponent() calls with robust ComponentResolver
- Add ComponentResolver integration in ManageAsset.cs for component lookups
- Add fallback to string-based lookup in ManageGameObject.cs for compatibility
Enhanced Error Handling:
- Surface specific ComponentResolver error context in ScriptableObject creation failures
- Add support for setting private [SerializeField] fields in property matching
- Improve debugging with detailed error messages
Assembly Definition Fixes:
- Configure TestAsmdef as Editor-only to prevent build bloat
- Add explicit TestAsmdef reference to test assembly for proper component resolution
- Fix ComponentResolverTests to use accessible CustomComponent instead of TicTacToe3D
Code Quality:
- Disable nullable reference types for legacy codebase to eliminate 100+ warnings
- Maintain backward compatibility while improving reliability
All 45 unit tests pass, ensuring no regressions while significantly improving robustness.

- Add intelligent property name suggestions when property setting fails
- Implement GetAllComponentProperties to enumerate available properties
- Add rule-based AI algorithm for property name matching (camelCase, spaces, etc.)
- Include comprehensive error messages with suggestions and full property lists
- Add Levenshtein distance calculation for fuzzy string matching
- Cache suggestions to improve performance on repeated queries
- Add comprehensive unit tests (11 tests) covering all ComponentResolver scenarios
- Add InternalsVisibleTo attribute for test access to internal classes
Examples of improved error messages:
- "Max Reach Distance" → "Did you mean: maxReachDistance?"
- Shows all available properties when property not found
- Handles Unity Inspector display names vs actual field names
All tests passing (21/21) including new ComponentResolver test suite.
The system eliminates silent property setting failures and provides
actionable feedback to developers.

See thread in #6, we can't use Unity MCP because it violates their trademark.
That name makes us look affiliated. We can use MCP for Unity

The Unity Editor was crashing with ValidTRS() assertions when attempting to get components from certain GameObjects like the Main Camera.
Investigation revealed the crash occurred during JSON serialization when reflection code accessed specific matrix properties (e.g., Camera.cullingMatrix, Transform.rotation, Transform.lossyScale). Accessing these properties appears to trigger internal Transform state validation failures, potentially due to interactions with the JSON serializer's reflection mechanism.
This fix addresses the issue by:
- Replacing LINQ iteration in GetComponentsFromTarget with a standard loop over a copied list to prevent potential premature serialization interactions.
- Explicitly skipping known problematic Camera matrix properties (cullingMatrix, pixelRect, rect) and generic matrix properties (worldToLocalMatrix, localToWorldMatrix) within GetComponentData's reflection logic.
- Retaining manual serialization for Transform component properties to avoid related reflection issues.
Moved serialization logic (GetGameObjectData, GetComponentData, metadata caching, JSON conversion helpers) from ManageGameObject tool to a dedicated GameObjectSerializer class in the Helpers namespace.
This improves separation of concerns and reduces the size/complexity of ManageGameObject.cs. Updated ManageGameObject to use the new helper class.
