Overview
CodexDesktop-Rebuild is a cross-platform Electron application that rebuilds the OpenAI Codex Desktop App for macOS, Windows, and Linux. It uses Electron Forge for building and packaging across multiple architectures (x64, arm64).
Installation
# Clone the repository
git clone https://github.com/Haleclipse/CodexDesktop-Rebuild.git
cd CodexDesktop-Rebuild
# Install dependencies
npm install
Development
Running in Development Mode
npm run dev
This starts the Electron app with hot-reloading enabled via Vite.

Main Process Development
Basic Electron Main Process Structure
// src/.vite/build/main.js
const { app, BrowserWindow } = require('electron');
const path = require('path');
let mainWindow;
function createWindow() {
mainWindow = new BrowserWindow({
width: 1200,
height: 800,
webPreferences: {
nodeIntegration: false,
contextIsolation: true,
preload: path.join(__dirname, 'preload.js')
},
icon: path.join(__dirname, '../../resources/electron.icns')
});
// Load the renderer
if (process.env.VITE_DEV_SERVER_URL) {
mainWindow.loadURL(process.env.VITE_DEV_SERVER_URL);
} else {
mainWindow.loadFile(path.join(__dirname, '../renderer/index.html'));
}
}
app.whenReady().then(createWindow);
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
if (BrowserWindow.getAllWindows().length === 0) {
createWindow();
}
});
IPC Communication
// Main process
const { ipcMain } = require('electron');
ipcMain.handle('execute-codex-command', async (event, command) => {
// Execute codex CLI command
const result = await executeCommand(command);
return result;
});
// Renderer process
const { ipcRenderer } = require('electron');
async function runCodex(command) {
const result = await ipcRenderer.invoke('execute-codex-command', command);
return result;
}
Renderer Development
Vite Configuration for Renderer
// vite.renderer.config.js
import { defineConfig } from 'vite';
import path from 'path';
export default defineConfig({
root: path.join(__dirname, 'src/webview'),
build: {
outDir: path.join(__dirname, '.vite/renderer'),
emptyOutDir: true
}
});
Frontend Integration
// src/webview/main.js
import './style.css';
// Initialize the app
document.addEventListener('DOMContentLoaded', () => {
const app = document.getElementById('app');
app.innerHTML = `
<div class="codex-interface">
<h1>Codex Desktop</h1>
<textarea id="prompt" placeholder="Enter your prompt..."></textarea>
<button id="execute">Execute</button>
<pre id="output"></pre>
</div>
`;
document.getElementById('execute').addEventListener('click', async () => {
const prompt = document.getElementById('prompt').value;
const output = await window.codex.execute(prompt);
document.getElementById('output').textContent = output;
});
});

Troubleshooting
Build Fails on Native Dependencies
# Rebuild native modules for Electron
npm install --save-dev @electron/rebuild
npx electron-rebuild
Icon Not Showing
Ensure icon files exist:
- macOS:
resources/electron.icns - Windows:
resources/electron.ico - Linux:
resources/electron.png
Code Signing Issues on macOS
// forge.config.js
module.exports = {
packagerConfig: {
osxSign: {
identity: process.env.APPLE_IDENTITY,
'hardened-runtime': true,
entitlements: 'entitlements.plist',
'entitlements-inherit': 'entitlements.plist',

Cross-Platform Build Issues
Use Docker for consistent builds:
docker run --rm -v $(pwd):/project electronuserland/builder:wine \
/bin/bash -c "cd /project && npm install && npm run build:win-x64"
Common Patterns
Adding Custom Menu
const { Menu } = require('electron');
const template = [
{
label: 'File',
submenu: [
{ role: 'quit' }
]
},
{
label: 'Edit',
submenu: [
{ role: 'undo' },
{ role: 'redo' },
{ type: 'separator' },
{ role: 'cut' },
{ role: 'copy' },
{ role: 'paste' }
]
}
];
const menu = Menu.buildFromTemplate(template);
Menu.setApplicationMenu(menu);
Auto-Update Configuration
const { autoUpdater } = require('electron-updater');
autoUpdater.checkForUpdatesAndNotify();
autoUpdater.on('update-available', () => {
// Notify user
});
autoUpdater.on('update-downloaded', () => {
// Prompt to restart
autoUpdater.quitAndInstall();
});
Environment-Specific Configuration
// Check environment
const isDev = process.env.NODE_ENV === 'development';
if (isDev) {
// Enable DevTools
mainWindow.webContents.openDevTools();
}

Popular ai & agents skills
google-agents-cli-publish
google/agents-cli
This skill should be used when the user wants to "publish an agent", "publish my ADK agent", "register an agent with Gemini", "publish to Gemini" (formerly Gemini Enterprise), or needs guidance on the agents-cli publish gemini command. Also use when the user wants to "manage agents in Agent Registry", "list/update/delete registered agents", or "register an MCP server". Covers ADK vs A2A registration modes, programmatic and interactive usage, flag reference, auto-detection from deployment metadata, Agent Registry fleet management, and troubleshooting. Part of the agents-cli skills suite. Do NOT use for deployment (use google-agents-cli-deploy).
google-agents-cli-eval
google/agents-cli
This skill should be used when the user wants to "run an evaluation", "evaluate my agent", "evaluate my ADK agent", "write an eval dataset", "analyze eval failures", "compare eval results", "optimize agent", or needs guidance on the Gemini platform eval methodology and the Quality Flywheel. Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).
skill-creator
anthropics/skills
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
codex-pet
prime-skills/runcomfy-agent-skills
Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
