Solutions:
  1. Reinstall CCS:
     ${isWindows ? 'irm ccs.kaitran.ca/install | iex' : 'curl -fsSL ccs.kaitran.ca/install | bash'}

  2. Or create config manually:
     mkdir -p ~/.ccs
     cat > ~/.ccs/config.json << 'EOF'
{
  "profiles": {
    "glm": "~/.ccs/glm.settings.json",
    "default": "~/.claude/settings.json"

EOF`);

  } catch (e) {
    const isWindows = process.platform === 'win32';
    showError(`Invalid JSON in ${configPath}

Fix the JSON syntax or reinstall:
  ${isWindows ? 'irm ccs.kaitran.ca/install | iex' : 'curl -fsSL ccs.kaitran.ca/install | bash'}`);
    process.exit(1);
  }

  // Validate config has profiles object
  if (!config.profiles || typeof config.profiles !== 'object') {
    const isWindows = process.platform === 'win32';
    showError(`Config must have 'profiles' object

See config.example.json for correct format
Or reinstall:
  ${isWindows ? 'irm ccs.kaitran.ca/install | iex' : 'curl -fsSL ccs.kaitran.ca/install | bash'}`);
    process.exit(1);
  }

  return config;

// Get settings path for profile

  // Validate profile name

Use only alphanumeric characters, dash, or underscore.`);

Available profiles:

  // Validate settings file exists
  if (!fs.existsSync(expandedPath)) {
    const isWindows = process.platform === 'win32';
    showError(`Settings file not found: ${expandedPath}

Solutions:
  1. Create the settings file for profile '${profile}'
  2. Update the path in ${getConfigPath()}
  3. Or reinstall: ${isWindows ? 'irm ccs.kaitran.ca/install | iex' : 'curl -fsSL ccs.kaitran.ca/install | bash'}`);

  // Validate settings file is valid JSON
  try {

    JSON.parse(settingsContent);
  } catch (e) {
    showError(`Invalid JSON in ${expandedPath}

Details: ${e.message}

Solutions:
  1. Validate JSON at https://jsonlint.com
  2. Or reset to template: echo '{"env":{}}' > ${expandedPath}
  3. Or reinstall CCS`);
