 ### Project Artifact Purge
 
-Remove build artifacts from old projects to reclaim disk space. Fast parallel scanning targets `node_modules`, `target`, `build`, `dist`, `.next`, `.gradle`, `venv`, and similar directories.
+Clean old build artifacts (`node_modules`, `target`, `build`, `dist`, etc.) from your projects to free up disk space.
 
 ```bash
-mo purge --dry-run    # Preview cleanup (recommended)
-mo purge              # Clean old project artifacts
+mo purge

-**Safety:** Only scans common project directories, skips recently modified projects (7 days), and requires artifacts at least 2 levels deep to avoid system files.
-
-**Performance:** Uses macOS Spotlight index (mdfind) for lightning-fast scanning, with parallel search across multiple directories.
+> **Use with caution:** This will permanently delete selected artifacts. Review carefully before confirming. Recent projects (< 7 days) are marked and unselected by default.
