# Disk Cleaner - AI-Assisted Disk Space Management

You have access to `diskclean.sh`, a disk scanning and cleaning tool. Install it by copying `diskclean.sh` to a location on your PATH, or run it directly from this skill's directory.

Setup

# Make executable (if not already)
chmod +x diskclean.sh

# Optional: symlink to PATH
ln -sf "$(pwd)/diskclean.sh" /usr/local/bin/diskclean

Commands

# Full scan:returns JSON with all reclaimable items
./diskclean.sh scan

# Preview safe-tier auto-deletions (dry run, default)
./diskclean.sh clean --dry

# Execute safe-tier deletions
./diskclean.sh clean --confirm

# Show last scan results
./diskclean.sh report

# Show scan history over time
./diskclean.sh history

How to Use This Skill

When the user asks to scan or clean disk space:

1. **Run a scan first**: Always start with `diskclean.sh scan`

2. **Summarize findings conversationally**: Group items by category, show top offenders by size, report total reclaimable space

3. **Explain the tiers clearly**:

- **Safe tier** (auto-deletable): Items matching a strict whitelist AND older than the age gate (7-14 days). These are regenerable artifacts like `node_modules`, `__pycache__`, build caches, package manager caches.

- **Suggest tier** (needs approval): Everything else:Docker, downloads, venvs, trash. Present these as recommendations and ask the user what they want to do.

4. **For safe-tier cleanup**: Run `diskclean.sh clean --dry` first to show what would be deleted, then `diskclean.sh clean --confirm` only after user approves

5. **For suggest-tier items**: Present them individually or grouped by category. If the user approves specific items, delete them manually with `rm -rf` (after confirming the path is under $HOME)

Presentation Format

When presenting scan results, use this structure:

## Disk Scan Results

**Total reclaimable: X.X GB**
- Safe tier (auto-cleanable): X.X GB
- Needs your review: X.X GB

### Safe to Auto-Clean
| Category | Size | Age | Path |
|----------|------|-----|------|
| ... | ... | ... | ... |

### Needs Your Review
| Category | Size | Age | Path |
|----------|------|-----|------|
| ... | ... | ... | ... |

Safety Rules

How It Works

Tiered Safety Model

**Safe tier** = whitelisted category + age gate met. Auto-deletable with `--confirm`.

**Suggest tier** = everything else. Requires explicit user approval.

Categories Scanned

| Category | What | Safe Tier | Age Gate |

|----------|------|-----------|----------|

| node_modules | Node.js dependencies (with package.json sibling) | Yes | 7 days |

| python_cache | `__pycache__`, `.pytest_cache` | Yes | 7 days |

| python_venv | `.venv/`, `venv/` | No |:|

| build_output | `build/`, `dist/`, `.next/`, `target/` | Yes | 7 days |

| go_cache | Go module + build cache | Yes | 14 days |

| homebrew_cache | Homebrew download cache | Yes | 14 days |

| npm_yarn_pnpm_cache | npm/yarn/pnpm caches | Yes | 14 days |

| pip_cache | pip download cache | Yes | 14 days |

| xcode_derived | Xcode DerivedData | Yes | 7 days |

| docker | Docker images, volumes, build cache | No |:|

| large_download | Files >100MB in Downloads | No |:|

| installer_archive | .dmg/.pkg/.zip/.iso in Downloads | No |:|

| logs | macOS logs (>50MB) | Yes | 30 days |

| crash_reports | Diagnostic reports (>10MB) | Yes | 30 days |

| ds_store | .DS_Store files | Yes | 0 days |

| trash | ~/.Trash contents | No |:|
