What it does

Win11 Storage Governance is an agent skill from Nongfsq/win11-storage-governance-kit. Create safe, privacy-preserving Windows 11 C-drive cleanup, storage migration, cache relocation, package-manager policy, and maintenance plans. Use when the user asks about Win11 C盘清理, disk bloat, AppData, Windows Installer, WinSxS, WindowsApps/UWP, winget, Scoop, dev caches, browser profiles, NVIDIA shader cache, package caches, or recurring cleanup automation across one or many Windows 11 devices.

Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/device-profile-template.md` and `references/runbook.md`).

It sits in DevOps & Cloud. It works with Windows and NVIDIA AI Platform. The repository describes itself as: Codex Skills kit for safe Windows 11 C-drive cleanup, storage migration, and cache governance. The licence is MIT.

When your agent uses it

  • The user asks about Win11 C盘清理
  • Windows Installer
  • WindowsApps/UWP
  • Browser profiles

Example prompts

  • “/win11-storage-governance”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Clarify scope: template-only, audit-only, or execute-on-this-device. Default to template-only unless the user explicitly asks to inspect…
  2. Load references/safety-model.md before recommending deletion, junctions, package-manager changes, or environment-variable changes.
  3. Load references/runbook.md when producing a full plan, checklist, migration guide, or remediation sequence.
  4. Load references/device-profile-template.md when the user wants a reusable template for another Windows 11 device.
  5. Produce a staged plan: observe, classify, clean, migrate, automate, verify, rollback.

What it can do on your machine

Read from SKILL.md and the folder at commit 32216f4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Win11 Storage Governance loads about 845 tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 107 tokens; SKILL.md has 361 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~107
When it runs · the whole SKILL.md, loaded when a task matches
~845
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Use when the user asks about Win11 C盘清理, disk bloat, AppData, Windows Installer, WinSxS, WindowsApps/UWP, winget, Scoop, dev caches, browser profiles, NVIDIA shader cache, package caches, or recurring cleanup automation across one or many Windows 11 devices.

Win11 Storage Governance

Workflow

  1. Clarify scope: template-only, audit-only, or execute-on-this-device. Default to template-only unless the user explicitly asks to inspect or change the local machine.
  2. Load references/safety-model.md before recommending deletion, junctions, package-manager changes, or environment-variable changes.
  3. Load references/runbook.md when producing a full plan, checklist, migration guide, or remediation sequence.
  4. Load references/device-profile-template.md when the user wants a reusable template for another Windows 11 device.
  5. Produce a staged plan: observe, classify, clean, migrate, automate, verify, rollback.

Privacy Rules

  • Do not read %USERPROFILE%, AppData, registry hives, package-manager state, shell history, environment variables, or local project folders unless the user explicitly requests a local audit/execution.
  • Do not copy personal paths, usernames, machine names, package lists, logs, or environment values into reusable templates.
  • When examples need paths, use neutral placeholders such as <User>, <DownloadDrive>, <DevCacheRoot>, and <ModelDrive>.
  • Treat this repository's example device layout as a model pattern, not as a user's private configuration.

Safety Gates

  • Never recommend manually deleting or junctioning C:\Windows\Installer, C:\Windows\WinSxS, C:\Program Files\WindowsApps, the whole AppData, the whole user profile, or the whole ProgramData.
  • Prefer official tools for Windows Update, WinSxS, Store/UWP apps, Visual Studio, drivers, and MSI repair.
  • Use junctions only for clearly regenerable caches, with backup, testing, and rollback steps.
  • For chat apps, browsers, password stores, databases, and device-bound app state, separate cache from user data before suggesting cleanup.
  • For destructive commands, present a dry-run or staged quarantine approach unless the user explicitly asks to execute and the target is already classified.

Output Contract

For a cleanup or migration plan, include:

  • Risk classification: safe clean, official-tool clean, migrate/configure, investigate, do-not-touch.
  • Concrete paths using placeholders unless doing an explicit local audit.
  • Commands only where they are safe and scoped; otherwise give GUI/offical-tool instructions.
  • Verification steps and rollback steps.
  • A recurrence plan that uses allowlists and age thresholds instead of broad deletion.

For local execution, include:

  • What will be inspected before running commands.
  • What will be changed, quarantined, or left untouched.
  • A summary of actions taken and remaining risks.

References

  • references/safety-model.md: deletion/migration red lines and risk categories.
  • references/runbook.md: practical staged procedure for Windows 11 storage governance.
  • references/device-profile-template.md: reusable profile template for adapting the plan to any Windows 11 device.
