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

• Never delete anything outside $HOME
• Never delete .git directories
• Never delete source code, documents, photos, or config files
• Never run clean --confirm without showing the user clean --dry output first
• Never delete suggest-tier items without explicit user approval per item or category
• Always verify a path exists before attempting deletion

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

Guardrails

• Only scans under $HOME (plus /tmp user files)
• node_modules only deleted if a package.json exists alongside (proof it's regenerable)
• Dry-run is the default:must pass --confirm to actually delete
• Every deletion is logged to ~/.openclaw/diskclean/deletion-log.jsonl
• All scan reports stored in ~/.openclaw/diskclean/scans/

Data Storage

• Scan reports: ~/.openclaw/diskclean/scans/scan-YYYYMMDD-HHMMSS.json
• Latest scan: ~/.openclaw/diskclean/latest-scan.json
• Deletion log: ~/.openclaw/diskclean/deletion-log.jsonl
