Verification Results

TypeScript Compilation

$ npx tsc --noEmit
# ✅ No errors

Module Loading

$ node -e "import('./dist/tools/index.js')..."
# ✅ Tools index exports: [ 'getAllTools', 'getToolCount', 'handleToolCall' ]
# ✅ Module loaded successfully

Tool Count

$ grep -r "name: 'xero_" src/tools/ | wc -l
# 84 tools (target: 60-80)

Next Steps (Optional Enhancements)

  1. Testing

  3. Advanced Features

    • Batch operations (process multiple records at once)
    • Webhook support for real-time updates
    • Advanced filtering DSL
    • Custom field support

  4. Documentation

    • Add JSDoc comments to all functions

    • Video tutorials

  5. Performance

    • Implement caching layer
    • Request deduplication
    • Parallel batch processing
