# CFN Skill Management - Fixes Applied

**Date:** 2025-12-08
**Status:** ✅ COMPLETED
**All tests passing:** 5/5 test suites, 65/65 tests

## Issues Fixed

### 1. Missing TypeScript Modules ✅
**Problem:** References to `src/cli/skill-loader` and `src/lib/database-service` that didn't exist.

**Solution:** Created missing modules:
- `/src/cli/skill-loader.ts` - High-performance skill loading with LRU caching and SHA256 validation
- `/src/lib/database-service.ts` - Database operations for skill management with SQLite support

### 2. Module Resolution Errors ✅
**Problem:** ES module imports missing `.js` extensions causing resolution failures.

**Solution:**
- Fixed import paths in created modules to use proper ES module syntax
- Updated relative import paths to match actual directory structure
- Added proper TypeScript dependencies

### 3. Test Configuration Issues ✅
**Problem:** Jest not configured for ES modules and TypeScript, causing test failures.

**Solution:**
- Created proper `jest.config.js` with ES module support
- Fixed `moduleNameMapping` → `moduleNameMapper` typo
- Configured ts-jest for ES modules with `preset: 'ts-jest/presets/default-esm'`
- Added proper transform configuration for TypeScript files

### 4. Dependencies ✅
**Problem:** Missing runtime dependencies for database operations.

**Solution:** Added to `package.json`:
- `sqlite: ^5.1.1`
- `sqlite3: ^5.1.6`
- `@types/sqlite3: ^3.1.8`
