Patch Codex Fast

Use this skill when the user asks to patch the local Codex App so API key mode can access Speed/Fast mode, the Plugins sidebar, plugin installation, or connectors.

Do not run the patch automatically just because this skill loads. First identify the OS and Codex install path, confirm the user wants to modify the installed app, and make a backup. This workflow modifies installed application files and Electron fuses.

What It Changes

• Enables Speed/Fast mode when authMethod is apikey.
• Enables the Plugins sidebar when using API key mode.
• Allows plugin installation and connector availability in API key mode.
• Extracts app.asar into an app/ folder and renames the original asar so Electron loads the unpacked app.
• Disables Electron fuses that otherwise force asar loading or integrity validation.

Requirements

• Node.js and npx.
• Python 3.
• macOS: permission to modify /Applications/Codex.app and re-sign the app.
• Windows: permission to modify %LOCALAPPDATA%\Programs\Codex.

Safety Rules

1. Always create app.asar.bak before patching if it does not already exist.
2. Keep rollback commands ready before applying patches.
3. Kill Codex before modifying resources.
4. If no patterns are patched, stop and report the changed patterns instead of guessing blindly.
5. If Codex crashes after patching, run the rollback for the OS.
6. Do not patch a different app path unless the user explicitly confirms it is the Codex App install.

macOS Rollback

cd /Applications/Codex.app/Contents/Resources
rm -rf app
[ -f app.asar1 ] && mv app.asar1 app.asar
[ -f app.asar.bak ] && cp app.asar.bak app.asar
codesign --force --deep --sign - /Applications/Codex.app
echo "Rolled back to original"

macOS Patch

pkill -x Codex 2>/dev/null; sleep 1

cd /Applications/Codex.app/Contents/Resources

[ ! -f app.asar.bak ] && cp app.asar app.asar.bak && echo "Backed up app.asar -> app.asar.bak"

rm -rf app

npx @electron/asar e ./app.asar app

mv ./app.asar ./app.asar1

When Codex Updates

Codex updates can change JS filenames and minified variable names. Use these searches inside <resources>/app/webview/assets.

Fast mode auth gate:

grep -rl "authMethod" *.js | xargs grep -l "fast_mode"
grep -o ".{0,50}authMethod.{0,100}fast_mode.{0,80}" <target_file>

Patch the target return value to return true.

Fast mode model availability:

grep -o ".{0,30}modelsByType.models.some.{0,50}" <target_file>

Replace the whole model availability expression with true.

Plugins sidebar gate:

grep -rl "pluginsDisabledTooltip" *.js
grep -o ".{0,5}pluginsDisabledTooltip" <target_file>

Change the gate ternary from X?(...) to 0?(...).

API key plugin detection:

grep -rl 'return e===.apikey.' *.js | grep -v locale
grep -o 'function e(e){return e===.apikey.}' <target_file>

Change it to function e(e){return false}.

Connector availability:

grep -rl "connector-unavailable" *.js | grep plugin
grep -o '.{0,10}connector-unavailable.{0,10}' <target_file>

Prefix the assignment with false&&, for example false&&(i=\connector-unavailable`)`.
