PC Storage Analysis and Cleanup

Problem

When disk space runs low, the hard part is not deciding whether to delete files, but figuring out what consumes space and what is safe to remove. On Windows, AppData, Electron updater caches, and LiteSandbox logs can grow large. On macOS, ~/Library/Caches, Xcode derived data, and Homebrew caches often accumulate.

How It Works

The skill follows a scan → analyze → report → cleanup workflow:
- Platform detection: uses platform.system() to choose Windows or macOS scan paths.
- Disk scan: outputs JSON data including size_bytes, size, and confidence.
- HTML report: renders disk summary, space distribution, large directories, and optimization suggestions with Chart.js.
- Tiered cleanup: groups actions by risk and generates cleanup_c_drive.ps1 or cleanup_mac.sh.

Boundaries

Scanning is read-only, while cleanup requires user confirmation. Windows should skip junction points; macOS must respect symbolic links and SIP. A confidence score below 7 should explain incomplete data, and caches from running apps may cause partial cleanup failures.
