How to use

  1. Copy the installation command and review the source package before installing it in your own agent environment.
  2. Check the source document for required tools, credentials and supported hosts.
  3. Describe your input and desired deliverable; review the output against the source material.

Before you start

  • Installation does not include a model subscription, API allowance or permission to access your files.
  • Repository stars and installation counts describe activity, not an independent quality or security test.

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.
