A review comment suggested adding a second path resolution and validation before
rm -rfto prevent TOCTOU/symlink attacks. After reconsideration, this suggestion was incorrect.Analysis
The existing code is already safe:
rm -rfdoes not follow symlinks by default—it removes the symlink itselfPath.resolve()validation already catches symlinks pointing to dangerous locations at check timeChanges
No code changes needed. Replied to the review comment withdrawing the suggestion and explaining why the current implementation is correct.
