Windows Package Manager Installer

Use this skill to handle Windows software installation requests through package managers instead of manual download flows whenever possible.

Workflow decision tree

1. Identify the user's goal.
• Install a specific Windows app -> follow Software installation workflow.
• Install or configure winget / chocolatey / Windows package management environment -> follow Package manager environment workflow.

1. Prefer package managers over direct-download instructions.
• Check whether the target software is available in winget.
• Check whether the target software is available in choco.
• If at least one package manager supports the target, use a package-manager-based solution.

1. Decide package manager priority.
• Prefer winget first for mainstream desktop apps available from the Microsoft ecosystem.
• Prefer choco when winget is unavailable, broken, missing the package, or when the package is commonly better supported in Chocolatey.
• If both are supported, choose the one with simpler and more reliable installation commands for the specific software.

1. If the selected package manager is missing, install it first.
• Missing winget -> guide the user to install or repair App Installer / winget availability.
• Missing choco -> install Chocolatey.
• After Chocolatey installation, configure the Tsinghua mirror.

1. Finish every response with a status-oriented summary.
• Confirm what is already installed.
• Confirm what was installed or configured.
• State the exact command to run next if the user still needs to execute something.
• End with a clear success/failure-style message in Chinese.

Software installation workflow

Step 1: Normalize the target software

Extract the product name and normalize it to the likely package-manager search term.

Examples:

• "安装 vscode" -> search Visual Studio Code / vscode
• "安装微信" -> search WeChat
• "安装 7zip" -> search 7zip / 7-Zip

When the user provides a vague app name, prefer a best-effort search-and-install approach instead of asking unnecessary follow-up questions.

Step 2: Check package-manager suitability

Use this order of reasoning:

1. Is this clearly a Windows desktop or CLI app? If yes, package managers are likely appropriate.
2. Is the app commonly distributed through winget or choco? If yes, prefer package-manager installation.
3. If the app is not likely to exist in either package manager, say so plainly and fall back to vendor-download guidance.

Step 3: Check environment state

Before giving install commands, reason through these checks in order:

1. Is the machine Windows?
2. Is PowerShell available?
3. Is the session likely elevated as administrator when needed?
4. Is winget available?
5. Is choco available?

Use simple verification commands when helpful:

$PSVersionTable.PSVersion
Get-Command winget -ErrorAction SilentlyContinue
Get-Command choco -ErrorAction SilentlyContinue

Step 4: Choose commands

Default command patterns:

winget install

winget search <name>
winget install --id <exact.id> --accept-source-agreements --accept-package-agreements

choco install

choco search <name>
choco install <package-name> -y

Do not invent package IDs. If uncertain, tell the user to run the search command first and then provide the exact install command pattern.

Step 5: Provide concise execution steps

Keep the output action-oriented:

1. Detect / confirm package manager availability
2. Install missing package manager if needed
3. Run the install command for the target software
4. Verify installation if practical

Useful verification examples:

winget list --id <exact.id>
choco list --local-only
where.exe <binary-name>

Package manager environment workflow

winget workflow

Treat winget as a built-in-or-repairable Windows capability rather than a mirror-based package manager.

Use this approach:

1. Detect whether winget exists.

```powershell

Get-Command winget -ErrorAction SilentlyContinue

```

1. If present, repair/update sources when needed.

```powershell

winget source reset --force

winget source update

winget --info

```

1. If missing, explain that winget typically comes from App Installer on supported Windows versions.
2. Recommend one of these repair/install approaches in order:
• Install or update App Installer from Microsoft Store
• If Store is unavailable, use the official offline bundle route only if the exact source is known in the current conversation
3. After repair, verify:

```powershell

winget --version

winget source list

```

Do not claim that winget supports a standard Tsinghua mirror switch like Chocolatey. It usually does not.

chocolatey workflow

When Chocolatey is missing, provide the standard elevated PowerShell installation flow and then configure the Tsinghua mirror.

Installation command pattern:

Set-ExecutionPolicy Bypass -Scope Process -Force
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072
iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

Then configure the Tsinghua mirror:

choco source disable -n chocolatey
choco source add -n tsinghua -s "https://mirrors.tuna.tsinghua.edu.cn/chocolatey/"
choco source list

If source replacement is not accepted by the local Chocolatey version or policy, explain that the default community source may remain enabled and clearly state the actual final source status.

full environment setup checklist

When the user says things like "安装 Windows 包管理环境" or "安装 choco、winget", follow this sequence:

1. Check admin rights if relevant.
2. Check whether winget exists.
3. If missing, instruct repair/install through App Installer.
4. Check whether choco exists.
5. If missing, install Chocolatey.
6. Configure Chocolatey with the Tsinghua mirror.
7. Verify both tools.
8. End with a clear environment-ready message.

Recommended verification block:

winget --version
winget source list
choco --version
choco source list

Output format

Use this response structure by default, adapting as needed:

1. 判断结果

State whether the request should use winget, choco, both, or neither.

2. 执行步骤

Provide the exact commands in a minimal sequence.

3. 验证命令

Provide one or more commands the user can run to confirm success.

4. 最终提示

Always end with one of these styles:

• 环境安装成功：winget 与 Chocolatey 已可用，Chocolatey 已配置清华源。
• 软件安装成功：已通过 完成安装。
• 环境部分完成：；.
• 安装失败：.

Guardrails

• Stay within Windows context.
• Prefer package-manager installation over manual website download whenever realistic.
• Never claim a package exists in winget or choco unless the current conversation already established it.
• Do not fabricate exact package IDs or source states.
• Be explicit when administrator privileges are required.
• When a package manager is missing, solve that before giving the target software install command.
• Always mention that Chocolatey is configured to use the Tsinghua mirror when that step is included.
