# Task 2C.1: Enhanced VS Code Configuration - COMPLETE ✅ **Completion Date:** November 1, 2025 **Status:** ✅ Complete **Estimated Time:** 2 hours **Actual Time:** 2 hours --- ## Objectives 1. ✅ Add development watch mode for auto-restart 2. ✅ Configure proper logging levels 3. ✅ Set up environment variables for configuration 4. ✅ Create configuration documentation 5. ✅ Add .env.example for development setup --- ## Changes Made ### 1. Package.json Enhancements **Added Scripts:** - `build:watch` - TypeScript watch mode (auto-compile on save) - `dev:watch` - Nodemon auto-restart for development - `start:debug` - Production debugging with full logs **Added Dependencies:** - `nodemon@^3.0.0` - Auto-restart on file changes ### 2. Configuration Module (`src/config.ts`) Created centralized configuration management: **Features:** - Environment variable parsing - Configuration validation - Type-safe configuration object - Singleton pattern for global access - Development mode detection - Debug mode detection **Supported Environment Variables:** - `LOG_LEVEL` - Error/Warn/Info/Debug logging - `NODE_ENV` - Production/Development mode - `DEBUG` - Debug namespace filtering - `CTS_CACHE_DIR` - Artifact cache directory - `CTS_MAX_FILE_SIZE` - Maximum file size to parse - `CTS_MAX_FILES` - Maximum files per scan - `CTS_ENABLE_PARALLEL` - Worker thread parallelization - `CTS_WORKER_COUNT` - Number of Workers - `CTS_ENABLE_CACHE` - Artifact caching toggle - `CTS_CACHE_TTL` - Cache expiration time - `CTS_PROFILE` - Performance profiling ### 3. VS Code Configuration Guide Updated `docs/VSCODE_MCP_SETUP.md` with: **Three Configuration Profiles:** 1. **Production** - Optimized for daily use 2. **Development** - Auto-reload on changes 3. **Debug** - Verbose logging for troubleshooting **Environment Variable Table:** - Complete reference of all config options - Default values documented - Purpose and usage explained ### 4. Environment Template (`.env.example`) Created comprehensive `.env.example` with: - Categorized configuration sections - Detailed comments for each variable - Recommended default values - Performance tuning guidance ### 5. Server Integration Updated `src/server.ts` to: - Load configuration on startup - Log configuration in structured format - Validate configuration values - Provide clear error messages --- ## Testing ### Configuration Loading Test ```bash cd /home/eric/Godot/ProtoBd/cts_mcp LOG_LEVEL=DEBUG node build/index.js ``` **Expected Output:** ``` [CTS MCP] Loading configuration... { "logLevel": "DEBUG", "nodeEnv": "production", "cacheDir": "/tmp/cts-cache", "maxFileSize": "5.00MB", ... } ``` ✅ **Result:** Configuration loads correctly and logs structured output ### VS Code Integration Test **Steps:** 1. Update VS Code `settings.json` with dev configuration 2. Reload VS Code window 3. Check Copilot output panel for configuration logs 4. Test tool execution ✅ **Result:** All tools execute with proper logging --- ## Documentation Created 1. **VS Code Setup Guide** (`docs/VSCODE_MCP_SETUP.md`) - 3 configuration profiles - Environment variable reference - Auto-reload setup instructions 2. **Environment Template** (`.env.example`) - Complete variable documentation - Categorized sections - Performance tuning guidance 3. **Configuration API** (`src/config.ts`) - Type-safe configuration interface - Validation logic - Helper functions --- ## Benefits ### For Development - 🔄 **Auto-restart** - Changes reflect immediately - 🐛 **Better debugging** - Verbose logs show execution flow - ⚡ **Faster iteration** - No manual rebuild/restart needed ### For Production - 📊 **Observability** - Configurable log levels - 🔒 **Safety** - Configuration validation - 🎯 **Flexibility** - Environment-specific settings ### For Users - 📖 **Clear docs** - Easy to understand and configure - 🛠️ **Troubleshooting** - Debug mode for issue diagnosis - ⚙️ **Customization** - Fine-tune performance --- ## Next Steps ### Immediate (Task 2C.2) **Enhanced Error Handling** - Implement ErrorCategory enum - Add ErrorSeverity levels - Create error recovery suggestions - Standardize tool response schemas ### Future (Task 2C.3+) - MCP Sampling Protocol integration - Result caching implementation - Parallel execution optimization - CI/CD integration - Documentation updates --- ## Files Modified ``` cts_mcp/ ├── package.json (MODIFIED - Added watch scripts) ├── .env.example (NEW - Environment template) ├── src/ │ ├── config.ts (NEW - Configuration module) │ └── server.ts (MODIFIED - Load config on startup) └── docs/ └── VSCODE_MCP_SETUP.md (MODIFIED - Added config profiles) ``` --- ## Validation Checklist - ✅ Development watch mode works (nodemon) - ✅ Logging levels configurable (ERROR/WARN/INFO/DEBUG) - ✅ Environment variables parsed correctly - ✅ Configuration validated on startup - ✅ Documentation comprehensive and clear - ✅ VS Code integration tested - ✅ E2E tests still passing - ✅ No regressions in existing functionality --- **Task Status:** ✅ **COMPLETE** **Ready for:** Task 2C.2 (Enhanced Error Handling)
