/install windows-disk-cleaner
Description
Safe Windows disk cleanup assistant. Scans any drive (defaults to C:), analyzes space usage across temp files, dev caches (npm/pip/conda/docker/gradle/maven)...
Usage Guidance
This skill appears to do what it says: scan a Windows disk and generate PowerShell cleanup commands. Before running anything, (1) review the generated PowerShell commands line-by-line, (2) run the scan and report in a non-destructive mode first, (3) back up important data (Downloads, Desktop, project folders) before bulk deletions, (4) be especially cautious with commands that remove Docker volumes, node_modules, .m2, or run Remove-Item with Recurse/Force, and (5) do not allow the agent to autonomously execute generated cleanup commands unless you explicitly trust it and understand each command. If you need more assurance, inspect the full scripts locally (they are included) or run the scan in a limited folder first.
Capability Analysis
Type: OpenClaw Skill
Name: windows-disk-cleaner
Version: 2.0.0
The skill bundle is a legitimate Windows disk cleanup utility designed to scan for temporary files, developer caches (npm, pip, docker, etc.), and large files. It follows a safe 'scan-first' approach where the PowerShell script (scripts/scan_disk.txt) only performs read-only analysis and the Python script (scripts/generate_report.py) generates an interactive HTML report for user review. No evidence of silent deletion, data exfiltration, or malicious persistence was found; all cleanup actions require the user to manually copy and execute generated commands from the report.
Capability Assessment
Purpose & Capability
Name/description match the included artifacts: a PowerShell scan script and a Python report generator. Required binaries (powershell, python3) are appropriate for the stated functionality and no unrelated credentials or services are requested.
Instruction Scope
SKILL.md and scripts are scoped to scanning, classifying, and producing a report. The PowerShell script is read-only (collects sizes, paths, and builds clean_command strings) and the Python script generates an HTML page that only produces PowerShell commands for the user to copy. The documentation consistently requires user confirmation before deleting. Note: some generated clean commands (e.g., docker system prune --volumes, Remove-Item on paths like node_modules or .m2) can remove persistent data — the skill marks those as review items and warns users, but they are potentially destructive if run.
Install Mechanism
No install spec; code is instruction-only plus bundled scripts. Nothing is downloaded or executed automatically during install, which keeps risk low.
Credentials
The skill reads standard environment variables (SystemDrive, TEMP, LOCALAPPDATA, USERNAME) and checks for locally installed developer tools (npm/pip/conda/docker). It requests no secrets or unrelated environment variables.
Persistence & Privilege
always:false (no forced inclusion). The skill can be invoked autonomously by the model by default (platform default), but its design requires explicit user confirmation to perform deletions. Users should still be cautious about allowing any skill to run commands autonomously, since deletion commands are produced and could be executed if an agent is granted that capability.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install windows-disk-cleaner - After installation, invoke the skill by name or use
/windows-disk-cleaner - Provide required inputs per the skill's parameter spec and get structured output
