+
+## Directory Structure (per tool)
+```
+tool-name/
+├── src/
+│   └── index.ts          # Full implementation
+├── dist/                 # Build output (auto-generated)
+│   ├── index.js         # ESM bundle
+│   └── index.d.ts       # TypeScript definitions
+├── package.json          # With tpmjs metadata
+├── tsconfig.json         # Extends @tpmjs/tsconfig/base.json
+└── tsup.config.ts       # Build configuration
+```
+
+## 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:
+```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
+

+
+const result = await streamText({
+  model: yourModel,
+  tools: {
+    reconciliationMatch: reconciliationMatchTool,
+  },
+  // ... your config
+});
+```
+
+## Next Steps
+
+To use these tools:
+
+1. **Build the packages:**
+   ```bash
+   pnpm --filter=@tpmjs/reconciliation-match... build
+   pnpm --filter=@tpmjs/feedback-themes... build
+   pnpm --filter=@tpmjs/churn-risk-score... build
+   pnpm --filter=@tpmjs/nps-analysis... build
+   pnpm --filter=@tpmjs/ticket-categorize... build
+   ```
+
+2. **Type-check:**
+   ```bash
+   pnpm --filter=@tpmjs/reconciliation-match type-check
+   # ... repeat for other tools
+   ```
+
+3. **Publish to npm (when ready):**
+   ```bash
+   pnpm changeset
+   pnpm changeset:version
+   pnpm changeset:publish
+   ```
+
+## Notes
+
+- All tools use keyword-based heuristics for classification
+- For advanced use cases, consider enhancing with AI model-powered analysis
+- Categorization logic can be customized per organization
+- All scoring algorithms use weighted factors that can be tuned
+- Tools are designed to be composable with other TPMJS tools
