Create core module: `src/core/myModule.ts` 2. Create tool wrapper: `src/tools/myTools.ts` 3. Register in `src/tools/index.ts` 4. Compile: `npm run build` ### 📊 CODE QUALITY ✅ Full TypeScript with strict mode ✅ Zod schemas for input validation ✅ Error safe wrappers throughout ✅ Exported function documentation ✅ No pseudocode - all implementations complete ✅ Proper async/await usage ✅ Platform detection for Windows/Linux/Mac ### 🎯 MONETIZATION READY Day-1 revenue model implemented: - License file-based activation - HMAC token validation - Expiration date enforcement - Licensee tracking - Support for bulk licensing - Development/production mode differentiation ### 📝 DOCUMENTATION Comprehensive README.md includes: - Installation steps - License activation process - Running instructions - Complete tool descriptions - Security model explanation - Integration examples (Claude Desktop, ChatGPT) - Development guide for adding tools - Troubleshooting section - Performance limits ### 🎓 NEXT STEPS 1. **Customize license terms** in `src/config/license.ts` 2. **Add more allowed commands** in `src/core/commands.ts` (development mode only) 3. **Extend with new tools** following the architecture pattern 4. **Configure environment variables** for production deployment 5. **Deploy** to user machines for real-world usage ### ✨ HIGHLIGHTS - **Zero pseudocode** - Every function is fully implemented - **Production-ready** - Error handling, logging, type safety - **Secure by default** - Command allow-listing, path validation, error sanitization - **Extensible** - Clear patterns for adding more tools - **Monetizable** - Built-in license validation from day 1 - **Cross-platform** - macOS, Windows, Linux support - **Well-documented** - README, inline comments, examples ### 📦 READY TO BUILD & DEPLOY The codebase is complete, compiled, and ready for: ✅ Development and testing ✅ Production deployment ✅ Commercial distribution ✅ Customer licensing **All 15 tools are production-ready with full error handling and security measures.** --- Generated: November 2025 Version: 1.0.0 MVP
