  "risk_level": "High",
  "why": "The command uses 'sudo rm -rf', which is highly destructive and irreversible. While the wildcard '*' limits the scope to the 'app' directory, it has several risks: 1) It does not match hidden files (dotfiles), leaving stale configurations, caches, or lock files behind. 2) A typo in the path (e.g., omitting 'app/') could delete the entire 'flight-recorder' directory. 3) Symlinks within the directory could point to unrelated system files, causing accidental deletion of critical data.",
  "safer_process": "1. Backup the directory first: 'sudo cp -a /models/flight-recorder/app /models/flight-recorder/app.bak'\n2. Dry run to verify exactly what will be deleted (including hidden files): 'sudo rm -rfv /models/flight-recorder/app/* /models/flight-recorder/app/.*'\n3. If the dry run looks correct, execute the deletion: 'sudo rm -rf /models/flight-recorder/app/* /models/flight-recorder/app/.*'\n4. Alternatively, use 'find' to safely remove all contents (including hidden files) without following symlinks: 'sudo find /models/flight-recorder/app/ -mindepth 1 -delete'"
