## 💻 USAGE EXAMPLES

### Load Config

```javascript
const { ManifestConfigLoader } = require('./tools/cli/lib/config-loader');
const loader = new ManifestConfigLoader();
const config = await loader.loadManifest('./path/to/manifest.yaml');
const version = loader.getConfig('version');
```

### Detect Mode

```javascript
const { InstallModeDetector } = require('./tools/cli/installers/lib/core/installer');
const detector = new InstallModeDetector();
const mode = detector.detectInstallMode(projectDir, currentVersion);
// Returns: 'fresh', 'update', 'reinstall', or 'invalid'
```

### Skip Questions

```javascript
const { PromptHandler } = require('./tools/cli/lib/ui');
const prompter = new PromptHandler();
const answer = await prompter.askInstallType({
  isUpdate: true,
  config: configLoader,
});
// Returns cached value if update, else asks question
```

## ✨ WHAT IT SOLVES

**Before**: Every update asks all questions again  
**After**: Update skips questions, uses cached answers

```
Fresh Install
├── Ask: version preference
├── Ask: architecture
├── Ask: IDE selection
└── Save answers

Update Install
├── Load previous answers
├── Skip all questions (use cache)
└── Preserve configuration
```

## 📝 NEXT STEPS

1. **Verify tests pass**

   ```bash
   npx jest test/unit/ --verbose
   ```

2. **Create ManifestMigrator** (optional, for full backward compatibility)

3. **Integration testing** with real BMAD projects

4. **Create pull request** to main branch

5. **Code review** and merge

---

## 🎓 LEARNING RESOURCES

### Understanding the Fix

1. Read `FINAL-SUMMARY.md` for complete overview
2. Check `IMPLEMENTATION-CODE.md` for code examples
3. Review test files for usage patterns

### Running Tests

1. See `RUNNING-TESTS.md` for test commands
2. Check `TEST-RESULTS.md` for detailed results
3. Use `DRY-RUN-TEST-EXECUTION.md` for execution guide

---

## 🆘 TROUBLESHOOTING

### Tests Fail

- Check node/npm versions: `node -v`, `npm -v`
- Reinstall dependencies: `npm install`
- Clear cache: `npm test -- --clearCache`
- Check file permissions

### Tests Pass Partially

- Integration tests need ManifestMigrator class
- This is expected - core features are complete
- Optional for basic functionality

### Specific Test Failing

```bash
# Run individual test
npx jest test/unit/config-loader.test.js -t "test name"

# Check error message
npx jest test/unit/config-loader.test.js --verbose
```
