Storage Clean

Overview

Reclaim disk space by measuring first, separating disposable caches from user data, and requiring confirmation before deletion. Prefer built-in cleanup tools and tool-specific prune commands over manual deletion. Treat user files, databases, virtual machines, model weights, Docker volumes, WSL distros, and unknown application state as high risk until proven otherwise.

Workflow

1. Identify the OS, target volume, free space, and whether the user wants analysis only or approved cleanup.
2. Measure read-only: volume pressure, top-level directory sizes, cache sizes, and large user-created files.
3. Load the platform reference for the target machine:

• macOS: references/macos.md
• Windows: references/windows.md
• Linux: references/linux.md

1. Group candidates by risk category:

• Low: re-downloadable caches and tool-managed temporary data.
• Medium: installers, disk images, archives, exports, logs, old downloads.
• High: documents, photos, project folders, databases, VM images, Docker volumes, WSL distros, local models, checkpoints.
• System-critical: OS internals and package installer state — only handle via official OS tools.

1. Present exact candidates with path, size, category, risk, command, admin requirement, and re-download/rollback cost.

• Never delete user files automatically, even if old or large.
• Never empty Trash or Recycle Bin without explicit confirmation.
• Never use broad recursive deletion on AppData, Library, ProgramData, Windows, project roots, or application support directories.
• Never manually delete system internals when an OS cleanup tool exists.
• Require explicit approval before pruning Docker volumes, unregistering WSL distros, removing toolchains, or deleting model caches.
• On Linux, never manually delete package databases, /var/lib/* state, /boot kernels, Docker/Podman storage internals, or Btrfs/Snapper/Timeshift snapshots.

1. Execute only explicitly approved actions.
2. Re-measure with the same baseline and report before/after free space plus anything intentionally left untouched. Re-read command output and verify counts, sizes, and free space — do not stop after running commands.

Platform Reference

Cross-platform: Determine where cleanup runs before choosing commands. Do not apply Windows deletion commands to mounted macOS paths, macOS shell commands to WSL/PowerShell paths, or Linux commands to Windows/macOS host storage unless the target is explicitly a Linux environment.

Reporting Format

For each proposed deletion or cleanup command, report:

Path:
Size:
Category:
Risk:
Why it is probably safe/risky:
Cleanup command:
Rollback/re-download cost:
Needs admin:
Requires explicit confirmation:

For each meaningful decision, include:

• Conclusion
• Reason
• Risk
• Next step
• Scope and validation method when changing or deleting anything
