Available Skills
Skills are organized into three categories:
File Management (macOS)
file-master
Mac file management master - a prompt-only orchestration skill that chains disk-cleaner, file-organizer, and doc-mindmap into a Clean > Organize > Analyze three-phase workflow. In a real-world demo, this workflow freed 120GB of disk space, organized 1,600+ files, and converted 4,000+ PPTs into a searchable knowledge base. (Watch the full walkthrough)
Three phases:
| Phase | Name | Description |
|---|
| Phase 1 | Clean | Disk cleanup with disk-cleaner |
| Phase 2 | Organize | File organization with file-organizer |
| Phase 3 | Analyze | Document analysis with doc-mindmap |
Only triggers when user needs combined multi-stage operations. For single tasks, use individual skills directly.

Smart Mac disk cleaning assistant powered by Mole. Features three-tier cleanup strategies, whitelist protection, categorized reports, and achievement pages. In a real-world test, it freed over 106GB of disk space across browser caches, app caches, system logs, and package manager artifacts.
