What it does
skill-c-cleaner runs the PowerShell script `analyze.ps1`, scans drive C across 12 categories and builds a report: system files, temp and browser caches, developer caches, large files, app data, messengers and duplicate runtimes. A separate block breaks down space taken by AI programs: installs, runtimes, models, extensions and update leftovers. Results go to the console, Markdown or JSON. The agent explains the findings, accounts for the user profile (developer, designer, regular user) and builds a staged plan: what to remove at once, what after a backup, what to move to another drive. Files are deleted by separate scripts in the `cleaners` folder: they show a preview first and reject the drive root, paths outside C: and any junctions.
Who it is for. Windows 10 and 11 users with a full drive C and developers with Docker, WSL and package-manager caches.
Good fit when
- Drive C has about 10 GB left, the system lags and it is unclear what takes the space.
- Docker and WSL keep growing and you must decide what to clean and what to move to another drive.
- Growth of used space is checked monthly and compared with the previous measurement.
- Before cleaning you want a preview of what will be deleted instead of pressing a button in a ready-made utility.
Not a fit when
- macOS and Linux: the scripts are PowerShell for Windows.
- A one-click cleanup with no questions: the skill goes through a report, a preview and a confirmation.
- An account without administrator rights: some operations are unavailable without them.

It works only on Windows 10 and 11 with PowerShell 5.1 or newer, and some operations need administrator rights. Only paths on drive C: are cleaned, and the scripts reject the drive root and any junctions and symbolic links. Vendor-managed storage, such as the WPS cache, is only routed to the vendor's own interface. The README tells you to clone `niuhai/skill-c-cleaner` while the catalog lists the hello-qingshan repository, so check the address before cloning. Reports and documentation are in Chinese.
How to disable. Delete the skill's folder from the agent's skills directory. Files already deleted cannot be restored, so back up before cleaning.
FAQ
How do I run the analysis?
From the skill folder run `.\analyze.ps1`. For a Markdown report add `-OutputFormat markdown -Template v6-ai-decision`, for JSON `-OutputFormat json`.
Does the skill delete files itself?
The analysis deletes nothing. Separate scripts in the `cleaners` folder do the cleaning, for example `clean-ai-footprints.ps1`, and they show a preview first.
Can I check only some categories?
Yes. The `-Categories` parameter takes category letters: `.\analyze.ps1 -Categories "C,D"` checks developer and browser caches. The `-Fast` switch enables a quick scan.
What does the AF category do?
It counts installs, runtimes, models, extensions, indexes, state and update leftovers of AI programs separately. With `-RecordGrowth` it records a baseline of used-space growth.
Are administrator rights required?
For some operations yes, as the README requirements say. The rest runs in a regular PowerShell session.

README in short
The author positions the skill as a decision layer above ordinary cleaners such as CCleaner and BleachBit: the analysis itself deletes nothing, and every finding comes with an explanation and steps. The README includes a 900-line sample report and four usage scenarios.
