Codex 插件修复技能

适用场景

0. 诊断：先查清楚再动手

# 1. Codex 版本
$pkg = Get-AppxPackage -Name "OpenAI.Codex"
Write-Host "Codex: $($pkg.Version)"

# 2. 运行时
$runtimeDir = "$env:LOCALAPPDATA\OpenAI\Codex\runtimes\cua_node"
Get-ChildItem $runtimeDir -Directory | ForEach-Object { Write-Host "Runtime: $($_.Name)" }
$runtimeHash = (Get-ChildItem $runtimeDir -Directory | Sort-Object LastWriteTime -Descending)[0].Name

# 3. Marketplace 状态
$codexHome = "$env:USERPROFILE\.codex"
$mktDest = "$codexHome\marketplaces\openai-bundled"
Write-Host "Marketplace exists: $(Test-Path $mktDest)"
if (Test-Path $mktDest) {
    Write-Host "Marketplace files: $((Get-ChildItem $mktDest -Recurse -File).Count)"
    Write-Host "Plugin version: $((Get-Content '$mktDest\plugins\computer-use\.codex-plugin\plugin.json' -Raw -ErrorAction SilentlyContinue | ConvertFrom-Json -ErrorAction SilentlyContinue).version)"
}

# 4. config.toml 关键项
$configPath = "$codexHome\config.toml"
$config = [System.Text.Encoding]::UTF8.GetString([System.IO.File]::ReadAllBytes($configPath))
Write-Host "Has marketplace section: $($config -match '\[marketplaces\.openai-bundled\]')"
Write-Host "Has computer_use: $($config -match 'computer_use = true')"
Write-Host "Has browser plugin: $($config -match 'browser@openai-bundled')"
Write-Host "Has chrome plugin: $($config -match 'chrome@openai-bundled')"
Write-Host "Runtime hash in config matches: $($config -match $runtimeHash)"

# 5. v0.142.5+ js_repl 特性检查
try {
    $features = codex features list 2>$null
    $jsReplLine = ($features | Select-String "js_repl").ToString()
    Write-Host "js_repl status: $jsReplLine"
    if ($jsReplLine -match "removed") {
        Write-Host "⚠️  js_repl 已被移除 (v0.142.5+) — MCP 工具无法暴露给模型，本轮修复无法完全生效"
    }
} catch {
    Write-Host "js_repl status: unable to check"
}

输出解读：

场景 A：自动更新后修复

流程：诊断 → 同步文件 → 修复 exports → 更新 config → Chrome 专属 → 清缓存 → 重启

A1. 确认版本

$pkg = Get-AppxPackage -Name "OpenAI.Codex"
$codexHome = "$env:USERPROFILE\.codex"
$mktDest = "$codexHome\marketplaces\openai-bundled"
$runtimeDir = "$env:LOCALAPPDATA\OpenAI\Codex\runtimes\cua_node"
$runtimeHash = (Get-ChildItem $runtimeDir -Directory | Sort-Object LastWriteTime -Descending)[0].Name
$msixMkt = "$($pkg.InstallLocation)\app\resources\plugins\openai-bundled"

A2. 同步 marketplace 文件

原理：Codex 自动更新后 MSIX 内置市场文件是最新的，但不会自动同步到用户目录。旧文件版本不匹配导致 Codex 不认。

cmd /c "rmdir /s /q `"$mktDest`"" 2>$null
[System.IO.Directory]::CreateDirectory($mktDest) | Out-Null

# EFS 绕过复制（WindowsApps 目录有加密）
function Copy-EFS { param($s,$d)
    if (!(Test-Path $d)) { [System.IO.Directory]::CreateDirectory($d)|Out-Null }
    Get-ChildItem $s | % {
        $dest = Join-Path $d $_.Name
        if ($_.PSIsContainer) { Copy-EFS $_.FullName $dest }
        else { [System.IO.File]::WriteAllBytes($dest, [System.IO.File]::ReadAllBytes($_.FullName)) }
    }
}
Copy-EFS $msixMkt $mktDest
Write-Host "Files: $((Get-ChildItem $mktDest -Recurse -File).Count)"

⚠️ 关键规则：

• 目标目录必须非隐藏（marketplaces\ ✅，.tmp\ ❌）
• 路径不要用 \\?\ 前缀
• .codex 目录有 EFS 加密，只能用 [System.IO.File]::WriteAllBytes 写文件

A3. 补充 computer-use 的 @oai/sky

$runtimeSky = "$runtimeDir\$runtimeHash\bin\node_modules\@oai\sky"
$destSky = "$mktDest\plugins\computer-use\node_modules\@oai\sky"
Copy-EFS $runtimeSky $destSky

A4. 修复 @oai/sky exports

原理：computer-use-client.mjs import 了 @oai/sky 的子路径，但 package.json 的 exports 字段没声明。Node.js 严格执行 exports 限制，拒绝导入。

$subpath = "./dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js"

# Marketplace 中的 @oai/sky
$skyPkg = "$mktDest\plugins\computer-use\node_modules\@oai\sky\package.json"
$json = Get-Content $skyPkg -Raw | ConvertFrom-Json
$json.exports | Add-Member -MemberType NoteProperty -Name $subpath -Value $subpath -Force
$json | ConvertTo-Json -Depth 10 | Set-Content $skyPkg -Encoding UTF8

# 运行时中的 @oai/sky
$runtimeSkyPkg = "$runtimeDir\$runtimeHash\bin\node_modules\@oai\sky\package.json"
$json2 = Get-Content $runtimeSkyPkg -Raw | ConvertFrom-Json
$json2.exports | Add-Member -MemberType NoteProperty -Name $subpath -Value $subpath -Force
$json2 | ConvertTo-Json -Depth 10 | Set-Content $runtimeSkyPkg -Encoding UTF8

A5. 更新 config.toml

原理：config.toml 受 EFS 加密 + Codex 沙箱保护，普通工具写不进去。必须用 [System.IO.File]::WriteAllBytes。

$configPath = "$codexHome\config.toml"
$bytes = [System.IO.File]::ReadAllBytes($configPath)
$content = [System.Text.Encoding]::UTF8.GetString($bytes)

A5a. 更新运行时 hash

Codex 更新后运行时 hash 会变，config.toml 中 4 处引用必须更新：

• notify
• command
• NODE_REPL_NODE_MODULE_DIRS
• NODE_REPL_NODE_PATH

if ($content -match 'cua_node\\([a-f0-9]+)\\') { $oldHash = $Matches[1] }
$content = $content -replace $oldHash, $runtimeHash

A5b. 确保 marketplace 节存在

[marketplaces.openai-bundled]
last_updated = "<ISO timestamp>"
source = '<codexHome>\\marketplaces\\openai-bundled'
source_type = "local"

if ($content -notmatch '\[marketplaces\.openai-bundled\]') {
    $escapedHome = $codexHome -replace '\\', '\\'
    $mktSection = @"
[marketplaces.openai-bundled]
last_updated = "$((Get-Date).ToUniversalTime().ToString('yyyy-MM-ddTHH:mm:ssZ'))"
source = '$escapedHome\\marketplaces\\openai-bundled'
source_type = "local"

"@
    $content = $content -replace '(\[plugins\])', "$mktSection`n`$1"
}

A5c. 确保插件已启用

if ($content -notmatch 'computer-use@openai-bundled') {
    $content = $content -replace '(\[plugins\.)', "[plugins.`"computer-use@openai-bundled`"]`nenabled = true`n`$1"
}
if ($content -notmatch 'browser@openai-bundled') {
    $content = $content -replace '(\[plugins\.)', "[plugins.`"browser@openai-bundled`"]`nenabled = true`n`$1"
}
if ($content -notmatch 'chrome@openai-bundled') {
    $content = $content -replace '(\[plugins\.)', "[plugins.`"chrome@openai-bundled`"]`nenabled = true`n`$1"
}

A5d. 更新版本号

$pluginVer = (Get-Content "$mktDest\plugins\chrome\.codex-plugin\plugin.json" -Raw | ConvertFrom-Json).version
$content = $content -replace 'BROWSER_USE_CODEX_APP_VERSION = "[^"]*"', "BROWSER_USE_CODEX_APP_VERSION = `"$pluginVer`""

A5e. 确保 features 开启

if ($content -notmatch 'computer_use = true') {
    $content = $content -replace '\[features\]', "[features]`ncomputer_use = true`nmemories = true"
}

A5f. 写入

[System.IO.File]::WriteAllBytes($configPath, [System.Text.Encoding]::UTF8.GetBytes($content))

A6. Chrome 插件专属

见 场景 C。

A7. 清理缓存

cmd /c "rmdir /s /q `"$codexHome\plugins\cache\openai-bundled`"" 2>$null

⚠️ v0.142.5+ 已知限制

Codex v0.142.5 及更高版本中，js_repl 和 tool_search 特性被标记为 removed。 即使所有文件同步正确、config.toml 配置完美，MCP 工具（mcp__node_repl__js）也无法暴露给模型。

验证方法：

codex features list | Select-String "js_repl"

如果输出包含 removed，以下功能将不可用：

• Computer Use 插件（sky.list_apps(), sky.click() 等）
• Codex 内置 browser / chrome 插件

替代方案：

• 降级到 Codex v0.141.x 或更早版本
• 使用 Hermes 的 computer_use 工具（功能等价，无此限制）

本工具集修复的是文件层面的问题（marketplace 同步、exports、config）。架构层面的特性移除目前无法通过文件修复解决。

A8. 最终验证

Write-Host "=== 验证结果 ==="
Write-Host "Marketplace: $((Get-ChildItem $mktDest -Recurse -File).Count) files"
Write-Host "Plugin ver: $((Get-Content '$mktDest\plugins\computer-use\.codex-plugin\plugin.json' -Raw|ConvertFrom-Json).version)"
Write-Host "Config OK: $(([System.Text.Encoding]::UTF8.GetString([System.IO.File]::ReadAllBytes($configPath))) -match '\[marketplaces\.openai-bundled\]')"
Write-Host "Chrome reg: $(cmd /c 'reg query HKCU\Software\Google\Chrome\NativeMessagingHosts\com.openai.codexextension 2>&1')"

重启 Codex Desktop。

场景 B：更换 API 供应商后修复

原理：更换供应商时 Codex 会重写 config.toml，清空 marketplace 配置、插件条目、features 等。

B1. 更换前备份（下次用）

$backupDir = "$env:USERPROFILE\.codex\backups"
New-Item -ItemType Directory -Path $backupDir -Force | Out-Null
$timestamp = (Get-Date).ToString("yyyyMMdd-HHmmss")
Copy-Item "$env:USERPROFILE\.codex\config.toml" "$backupDir\config-$timestamp.toml"
Write-Host "Backed up to: $backupDir\config-$timestamp.toml"

B2. 更换后修复

更换供应商完成后，跑一遍 场景 A 的诊断，看哪些配置丢了，然后跳到对应的 A5 子步骤补回。

最常丢的：

• A5b — marketplace 节
• A5c — browser / chrome 插件条目
• A5e — computer_use = true

场景 C：Chrome 插件专属

原理：Chrome 插件需要通过 Windows 注册表 + Native Messaging 机制与 Chrome 浏览器通信。仅复制 marketplace 文件不够。

$extId = "hehggadaopoacecdllhhajmbjkdcmajg"  # 来自 extension-id.json
$extHost = "$mktDest\plugins\chrome\extension-host\windows\x64\extension-host.exe"
$extHostDir = Split-Path $extHost -Parent
$runtimeDir = "$env:LOCALAPPDATA\OpenAI\Codex\runtimes\cua_node"
$runtimeHash = (Get-ChildItem $runtimeDir -Directory | Sort-Object LastWriteTime -Descending)[0].Name

# C1. Native Messaging Manifest
$manifestDir = "$env:LOCALAPPDATA\OpenAI\extension"
[System.IO.Directory]::CreateDirectory($manifestDir) | Out-Null
$manifest = @{
    allowed_origins = @("chrome-extension://$extId/")
    description = "Codex chrome native messaging host"
    name = "com.openai.codexextension"
    path = $extHost
    type = "stdio"
} | ConvertTo-Json -Depth 3
[System.IO.File]::WriteAllBytes("$manifestDir\com.openai.codexextension.json",
    [System.Text.Encoding]::UTF8.GetBytes($manifest))

# C2. 注册表
cmd /c "reg add `"HKCU\Software\Google\Chrome\NativeMessagingHosts\com.openai.codexextension`" /ve /t REG_SZ /d `"$manifestDir\com.openai.codexextension.json`" /f"

# C3. Extension Host 配置
$appConfig = @{
    browserClientPath = "$mktDest\plugins\chrome\scripts\browser-client.mjs"
    channel = "prod"
    extensionId = $extId
    nodePath = "$runtimeDir\$runtimeHash\bin\node.exe"
    nodeReplPath = "$runtimeDir\$runtimeHash\bin\node_repl.exe"
    proxyHost = "127.0.0.1"
    proxyPort = 0
} | ConvertTo-Json -Depth 2
[System.IO.File]::WriteAllBytes("$extHostDir\extension-host-config.json",
    [System.Text.Encoding]::UTF8.GetBytes($appConfig))

场景 D：备份与恢复

D1. 创建备份

$codexHome = "$env:USERPROFILE\.codex"
$backupDir = "$codexHome\backups"
$timestamp = (Get-Date).ToString("yyyyMMdd-HHmmss")
New-Item -ItemType Directory -Path $backupDir -Force | Out-Null

# 备份 config.toml
Copy-Item "$codexHome\config.toml" "$backupDir\config-$timestamp.toml"

# 备份 marketplace
if (Test-Path "$codexHome\marketplaces") {
    Compress-Archive -Path "$codexHome\marketplaces" -DestinationPath "$backupDir\marketplaces-$timestamp.zip" -Force
}

Write-Host "Backup complete: $backupDir"
Get-ChildItem $backupDir | Select-Object Name, Length

D2. 恢复

$backupDir = "$env:USERPROFILE\.codex\backups"
$latestConfig = Get-ChildItem "$backupDir\config-*.toml" | Sort-Object LastWriteTime -Descending | Select-Object -First 1

# 恢复 config
$bytes = [System.IO.File]::ReadAllBytes($latestConfig.FullName)
[System.IO.File]::WriteAllBytes("$env:USERPROFILE\.codex\config.toml", $bytes)

# 恢复 marketplace（如果有 zip）
$latestMkt = Get-ChildItem "$backupDir\marketplaces-*.zip" | Sort-Object LastWriteTime -Descending | Select-Object -First 1
if ($latestMkt) {
    Expand-Archive -Path $latestMkt.FullName -DestinationPath "$env:USERPROFILE\.codex\marketplaces" -Force
}

Write-Host "Restored from: $($latestConfig.Name)"
