# Storage Cleanup

Reclaim tens of gigabytes in one command. No config files, no dependencies, no damage.

## Why This Skill

Systems accumulate junk silently — IDE caches, old snap revisions, stale pip builds, forgotten trash, outdated kernels. Manually hunting them down wastes time and risks deleting the wrong thing.

This skill:
- **Scans 12+ cleanup targets** across both macOS and Linux in a single pass
- **Safe by default** — `--dry-run` shows exactly what would be cleaned before touching anything
- **Zero dependencies** — pure bash + awk, works on any stock macOS or Linux install
- **Cross-platform** — auto-detects OS and runs only what applies (no errors on missing tools)
- **Selective** — skip any category with `--skip-kernels`, `--skip-docker`, `--skip-brew`, `--skip-snap`
- **Reports savings** — shows before/after disk usage and exact bytes freed

## Quick Start

```bash
# Preview what would be cleaned (safe, changes nothing)
bash scripts/cleanup.sh --dry-run

# Clean everything
bash scripts/cleanup.sh --yes

# Clean but keep Docker and old kernels
bash scripts/cleanup.sh --yes --skip-docker --skip-kernels
```

## What Gets Cleaned

### Both Platforms
| Target | Typical Size | Notes |
|--------|-------------|-------|
| Trash | 1–50 GB | macOS `~/.Trash`, Linux `~/.local/share/Trash` |
| Stale `/tmp` | 1–10 GB | pip/npm/rust build dirs older than 60 min |
| pip cache | 50–500 MB | `pip cache purge` |
| Go build cache | 100 MB–2 GB | `go clean -cache` |
| pnpm / yarn / node caches | 50–500 MB | Safe to regenerate |
| JetBrains IDE cache | 1–10 GB | IntelliJ, PyCharm, WebStorm, etc. |
| Whisper model cache | 1–5 GB | Redownloads on demand |
| Chrome / Firefox cache | 200 MB–2 GB | Browsing cache only |
| Playwright browsers | 200 MB–1 GB | Redownloads on demand |
| Docker dangling images | 0–10 GB | Only unreferenced images + build cache |

### Linux Only
| Target | Typical Size | Notes |
|--------|-------------|-------|
| Apt cache | 200 MB–2 GB | `apt clean...
