Key Findings

Fixed Issues

1. Brand Hallucination - AI no longer lists manufacturers it hasn't verified
2. John Deere False Positive - Correctly reports "not found" instead of claiming we sell it
3. Tool Usage - All 4 tools (searchParts, getPartDetails, autocomplete, checkAvailability) working correctly

Remaining Considerations

1. AI sometimes says "we may be able to special order" after not finding parts - this is acceptable behavior (directs to customer service)
2. Response streaming working correctly with real-time deltas
3. Multi-step tool calls working (up to 2-3 searches per query)

Tool Usage Statistics

Recommendations

1. Monitor - Set up logging for tool failures in production
2. Expand Tests - Add more manufacturer verification tests as catalog changes
3. Load Testing - Test concurrent users and response times
4. Edge Cases - Test with unusual characters, long queries, empty queries
