Tool Consolidation Opportunities (32-40% reduction possible)

1. Image Upload Consolidation - Merge 3 upload tools into 1 unified tool

   • Drop base64 support, keep file paths and URLs only
   • Eliminate user confusion about which tool to use
   • Quick win with high impact

2. Vehicle Creation Simplification - Reduce 4-step workflow to 2 steps

   • Combine spec finding and comparison
   • Unified creation interface
   • Clearer user journey

3. Reference Data Deduplication - Remove 6 duplicate tools

   • Keep navigation API tools, remove legacy reference API
   • Consistent naming and behavior
   • See for detailed plans
