# FreeCAD AI Addon - Provider Service Import Fix - COMPLETED ## Issue Summary **Date**: 2025-06-10 **Time**: 15:59-16:30 **Log Error**: "Could not import provider service - proceeding without it" ## Root Cause Analysis The FreeCAD AI addon logs showed a critical import failure for the provider service, which was preventing: 1. Provider synchronization between tabs 2. Agent manager initialization 3. Proper provider selection functionality **Root Cause**: Missing `get_provider_service()` function in `ai/provider_integration_service.py` - The file contained a `ProviderIntegrationService` class with singleton pattern - But no getter function to access the singleton instance - Main widget was trying to import `get_provider_service` which didn't exist ## Fixes Implemented ### 1. Added Missing Singleton Access Function ✅ **File**: `/freecad-ai/ai/provider_integration_service.py` **Changes**: ```python # Global singleton instance access function _provider_service_instance = None def get_provider_service(): """ Get the singleton instance of ProviderIntegrationService. Returns: ProviderIntegrationService: The singleton service instance """ global _provider_service_instance if _provider_service_instance is None: _provider_service_instance = ProviderIntegrationService() return _provider_service_instance ``` ### 2. Cleaned Up Configuration Duplicates ✅ **File**: `/freecad-ai/addon_config.json` **Issues Fixed**: - Removed duplicate `anthropic`/`Anthropic` entries → kept normalized `anthropic` - Removed duplicate `google`/`Google` entries → kept normalized `google` - Removed duplicate `OpenRouter`/`openrouter` entries → kept `openrouter` - Updated `default_provider` from `"Google"` to `"google"` for consistency ### 3. Leveraged Existing Normalization Logic ✅ **Existing Features**: - `_resolve_provider_name()` function already handles case normalization - `_cleanup_duplicate_providers()` automatically removes duplicates during initialization - Provider name resolution system already in place ## Expected Results 1. **Provider Service Import**: Should now work without "Could not import provider service" error 2. **Provider Sync**: Provider changes in provider tab should sync to chat tab 3. **Agent Manager**: Should initialize properly and be available for agent mode 4. **Configuration**: Clean, normalized provider names without duplicates ## Task Status Update - **BUGFIX_003**: Moved from `in_progress` to `completed` - **Next Focus**: Test suite development and missing tools implementation ## Testing Recommendations 1. Restart FreeCAD and verify no import errors in logs 2. Test provider selection synchronization between tabs 3. Verify agent manager is available when switching to agent mode 4. Check that provider configuration persists correctly ## Files Modified 1. `/freecad-ai/ai/provider_integration_service.py` - Added `get_provider_service()` function 2. `/freecad-ai/addon_config.json` - Cleaned up duplicate provider entries 3. `/tasks/BUGFIX_003_*` - Renamed to completed status This fix addresses the core provider service architecture issue that was causing multiple related problems in the FreeCAD AI addon.
