* feat: add Codex CLI client support with config.toml handling
* feat: add config helpers for managing Codex and MCP server configurations
* feat: add TOML array parsing support for multi-line and trailing comma formats
* fix: handle TOML inline comments in section headers during parsing
* fix: strip TOML comments before processing section headers
* fix: improve JSON parsing to handle escaped single quotes in config strings
* Use Tommy for TOML parsing
It's a single file and OSS, easy to integrate into Unity
* fix: patched Tommy’s literal-string handling so doubled single quotes inside literal strings are treated as embedded apostrophes instead of prematurely ending the value
* Don't overwrite MCP configs while testing
Seeing random JSON in my codex config was pretty annoying
* PR Feedback
* Keep Tommy compatible with Unity 2021
* Re-include Tommy's license
Probably a good habit to keep all 3rd party licenses and copyrights, even if they're also MIT licenses
* Move the current test to a Tools folder
* feat: add env object and disabled flag handling for MCP client configuration
* Format manual config specially for Windsurf and Kiro
* refactor: extract config JSON building logic into dedicated ConfigJsonBuilder class
* refactor: extract unity node population logic into centralized helper method
* refactor: only add env property to config for Windsurf and Kiro clients
If it ain't broke with the other clients, don't fix...
* fix: write UTF-8 without BOM encoding for config files to avoid Windows compatibility issues
* fix: enforce UTF-8 encoding without BOM when writing files to disk
* refactor: replace execute_menu_item with enhanced manage_menu_item tool supporting list/exists/refresh
* Update meta files for older Unity versions
* test: add unit tests for menu item management and execution
* feat: add tips for paths, script compilation, and menu item usage in asset creation strategy
* Use McpLog functionality instead of Unity's Debug
* Add telemetry
* Annotate parameters
More info to LLMs + better validation
* Remove the refresh command
It's only ever useful in the context of listing menu items
* Updated meta files since running in Unity 2021
* Slightly better README
* fix: rename server-version.txt to server_version.txt and update menu item description
CodeRabbit fixes:
- Fix Python test assertions to use assert instead of print/return
- Update version consistency: server_version.txt from 3.2.0 to 3.3.0
- Assembly definition references already correctly configured
Greptile style fixes:
- Add missing newlines at end of Unity meta files and source files
- Fix test logic assumptions: use GreaterOrEqual instead of exact counts
- Make test assertions more robust for fuzzy matching algorithms

The TryResolve_PrefersPlayerAssemblies test was failing in CI because it referenced
TicTacToe3D.cs which exists only locally and is not committed to the repository.
- Replace test reference from "TicTacToe3D" to "CustomComponent"
- CustomComponent exists in Assets/Scripts/TestAsmdef/ and is tracked in git
- CustomComponent is properly compiled into the TestAsmdef Player assembly
- Add explicit assertion to verify resolution from correct TestAsmdef assembly
- Test maintains same functionality: verifying ComponentResolver finds user scripts from Player assemblies

- 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.

- Replace Assembly.LoadFrom with already-loaded assembly search
- Prioritize Player assemblies over Editor assemblies using CompilationPipeline
- Support both short names and fully-qualified component names
- Add comprehensive caching and error handling with disambiguation
- Use Undo.AddComponent for proper editor integration
- Handle ReflectionTypeLoadException safely during type enumeration
- Add fallback to TypeCache for comprehensive type discovery in Editor
Fixes component resolution across custom assembly definitions and eliminates
"Could not load the file 'Assembly-CSharp-Editor'" errors.
Tested with:
- Built-in Unity components (Rigidbody, MeshRenderer, AudioSource)
- Custom user scripts in Assembly-CSharp (TicTacToe3D)
- Custom assembly definition components (TestNamespace.CustomComponent)
- Error handling for non-existent components
