  targetPath: 'src/',           // Path to lint
  maxClones: 5,                 // Max code duplicates to display
  width: 120,                   // Terminal width for formatting
  noFix: false,                 // Enable auto-fix (default)
  noPreflight: false,           // Run preflight checks (default)
  fixPeers: false,              // Don't fix peer dependencies (default)
});

if (exitCode === 0) {
  console.log('✅ No errors found!');
} else {
  console.log('❌ Linting errors detected');
