Key Functions:

• phoneticSimilarity() - Sound-alike detection
• visualSimilarity() - Look-alike detection
• levenshteinDistance() - Edit distance calculation
• assessRisk() - Risk level determination
• getRelevantClasses() - Nice Classification mapping

4. Expense Categorize (expense-categorize)

Category: finance
Path: /packages/tools/official/expense-categorize

Features:

• Categorizes into 18 standard accounting categories
• Keyword-based pattern matching

5. Invoice Data Extract (invoice-data-extract)

Category: finance
Path: /packages/tools/official/invoice-data-extract

Features:

• Extracts vendor information (name, address, phone, email, tax ID)
• Parses line items with quantities and prices
• Extracts totals (subtotal, tax, total)
• Validates calculations (totals match line items)
• Supports multiple currencies (USD, EUR, GBP, JPY)
• Payment terms extraction

Key Functions:

• extractVendorInfo() - Vendor metadata extraction
• extractLineItems() - Line item parsing

• extractPaymentTerms() - Due date and net days

Technical Stack

All tools use:

• AI SDK: v6.0.0-beta.124 (not v4.0.0)
• Build: tsup with ESM format
• TypeScript: Strict mode with composite projects
• Exports: Both named and default exports
• Type Safety: Full TypeScript definitions

Build & Type-Check Results

All tools successfully: ✅ Pass TypeScript strict type-checking
✅ Build with tsup (ESM + DTS)
✅ Follow monorepo conventions
✅ Include proper tpmjs metadata

Package Metadata

Each tool includes proper tpmjs field in package.json:

{
  "tpmjs": {
    "category": "legal" | "finance",
    "frameworks": ["vercel-ai"],
    "tools": [
      {
        "name": "toolName",
        "description": "...",
        "parameters": [...],
        "returns": {...}
      }
    ]
  }
}

Implementation Philosophy

1. Heuristic-based: All tools use pattern matching and rules-based logic (not AI/LLM calls)
2. Production-ready: Full error handling, validation, and TypeScript types
3. Comprehensive: Each tool includes recommendations and warnings
4. Standards-compliant: Follow domain-specific standards (GDPR articles, Nice Classification, etc.)
5. Developer-friendly: Clear interfaces, extensive JSDoc comments
