Enhanced Configuration Management

Automatic Config Backup and Recovery

• Configuration files are now automatically backed up when corruption is detected
• If the main config file is corrupted, a timestamped backup is created (e.g., config.json.corrupted.1234567890)
• Users are notified of backup locations and provided with recovery instructions
• Example recovery message:

  Claude configuration file at ~/.claude/config.json is corrupted
  The corrupted file has been backed up to: ~/.claude/config.json.corrupted.1234567890
  A backup file exists at: ~/.claude/config.json.backup
  You can manually restore it by running: cp "~/.claude/config.json.backup" "~/.claude/config.json"

Improved Config File Locking

• Added file locking mechanism for configuration updates to prevent concurrent write conflicts
• If locking fails, the system gracefully falls back to non-locked saves with appropriate logging
