Codex Windows Fast Patch

# Codex Windows Fast Patch

Use this skill when the user says Codex Desktop was upgraded and the Fast Mode / Plugins / Goal patch disappeared, asks to repatch Codex on Windows, asks to verify whether Fast Mode is really being sent, asks to restore/register the local plugin marketplace, or asks to enable Chrome browser use or Windows Computer Use in Codex Desktop. Also use it when the language/locale setting reverts after restart, browser or plugin entries are hidden by availability gates, the Computer Control settings page shows "Any App" / "任意应用" as disabled by organization or unavailable in the current region, or the Connections / Codex mobile remote-control setup flow drops into an auth error loop on Windows.

## Platform Compatibility

This skill is Windows-only. It depends on the Windows Store/MSIX package layout, PowerShell, `Get-AppxPackage`, `makeappx.exe`, `signtool.exe`, Windows user environment variables, and Windows Computer Use helper paths.

Do not run this skill on macOS. A macOS adaptation needs a separate workflow for the Codex `.app` bundle, ASAR extraction and repacking, macOS code signing or quarantine handling, shell scripts, and macOS-specific Computer Use availability.

## Self-Update Preflight

Before doing substantive work with this skill, run the bundled self-update helper once, then reload this `SKILL.md` if it reports an update:

```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File "$env:USERPROFILE\.codex\skills\codex-windows-fast-patch\scripts\update-skill-from-github.ps1"
```

The helper checks `chen0416ccc-cpu/codex-windows-fast-patch-skill` on GitHub and synchronizes only the skill allowlist: `SKILL.md`, `agents`, `scripts`, `references`, and `assets`. 如果无法更新到最新版，则不要中断当前任务；继续使用本机已安装的当前版本完成工作，并在结果中说明未能更新。

If the normal workflow does not explain a restriction, plugin gate, Computer Use failure, or Codex mobile entry failure, read `references/restriction-debug-cases.md` before editing scripts or repatching.

## Config Backup Rule

Before any action that can modify, regenerate, or overwrite `$env:USERPROFILE\.codex\config.toml`, create one timestamped backup of the current file for the task. This applies whether the agent uses bundled scripts, writes TOML manually, runs another helper, registers a marketplace, changes MCP servers, or repairs Computer Use.

The bundled scripts already back up an existing `config.toml` once per script run before their first write. If not using those scripts, do the backup explicitly before touching the file:

```powershell
$config = Join-Path $env:USERPROFILE '.codex\config.toml'
if (Test-Path -LiteralPath $config -PathType Leaf) {
  $backupDir = Join-Path (Split-Path -Parent $config) 'backups\config'
  New-Item -ItemType Directory -Force -Path $backupDir | Out-Null
  $backup = Join-Path $backupDir ('config.toml.' + (Get-Date -Format 'yyyyMMdd-HHmmss-fff') + '.manual.bak')
  Copy-Item -LiteralPath $config -Destination $backup -Force
  Write-Host "config.toml backup before overwrite: $backup"
}
```

Do not proceed with a config write if the backup of an existing config fails. After writing, validate TOML syntax with `tomllib` when Python is available.

## Default Workflow

1. If the task may modify `config.toml`, skills, marketplaces, or MCP server settings, create a state snapshot first:

```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File "$env:USERPROFILE\.codex\skills\codex-windows-fast-patch\scripts\manage-codex-backups.ps1" -Action Backup
```

2. Inspect current package status:

```powershell
Get
