💻 USAGE EXAMPLES

Load Config

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

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

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

🎓 LEARNING RESOURCES

Understanding the Fix

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

Running Tests

See RUNNING-TESTS.md for test commands
Check TEST-RESULTS.md for detailed results
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

# 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
