# Prerequisites for Using Codex CLI with the AI Website Cloner Template > Learn the prerequisites for using Codex CLI with the AI Website Cloner Template. Ensure Node.js 24+ and a working Codex CLI are installed to get started. - Repository: [JCodesMore/ai-website-cloner-template](https://github.com/JCodesMore/ai-website-cloner-template) - Tags: getting-started - Published: 2026-07-04 --- **You need Node.js 24 or newer and a working Codex CLI installation on your PATH to run the AI Website Cloner Template with OpenAI's Codex agent.** The **JCodesMore/ai-website-cloner-template** repository is designed to work with multiple AI coding agents, including Codex CLI. Understanding the prerequisites for using Codex CLI with this template ensures you can execute the `/clone-website` skill without environment errors. ## System Requirements The template requires **Node.js 24 or newer** to execute its build, lint, and type-checking scripts. According to the repository's [`README.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/README.md) at lines 74-78, this specific Node version is mandatory. Attempting to run the project with earlier versions will cause dependency installation failures or runtime errors during script execution. ## Codex CLI Installation You must have a **working Codex CLI installation** reachable on your `$PATH`. The CLI enables the agent to start and invoke the `/clone-website` skill. The [`README.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/README.md) lines 60-62 confirm Codex CLI as a supported agent in the Supported Platforms table. Install the CLI globally using npm: ```bash npm i -g @openai/codex-cli ``` Verify the installation by ensuring the `codex` command is available in your terminal before proceeding. ## Project Setup Steps Follow these steps to prepare the template for Codex CLI execution: 1. **Clone your own copy** of the template (do not clone the original repository directly): ```bash git clone https://github.com//.git cd ``` 2. **Install dependencies** using Node.js 24+: ```bash npm install ``` 3. **Install Codex CLI** if you haven't already: ```bash npm i -g @openai/codex-cli ``` 4. **Start the Codex agent** with Chrome integration: ```bash codex --chrome ``` 5. **Execute the cloning skill** against your target: ```bash /clone-website https://example.com ``` ## How the Template Recognizes Codex CLI The template automatically detects Codex CLI support through several key files: - **[`AGENTS.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/AGENTS.md)**: Serves as the central source-of-truth for supported agents, marking Codex CLI as compatible. - **`scripts/sync-skills.mjs`**: Regenerates the `/clone-website` skill for all platforms, ensuring Codex CLI receives the latest skill definition. - **[`.github/skills/clone-website/SKILL.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/.github/skills/clone-website/SKILL.md)**: Contains the actual skill definition that Codex CLI executes when you run the `/clone-website` command. No additional environment variables or secret keys are required for the template itself. ## Summary - **Node.js 24+** is mandatory for running the template's build and validation scripts according to [`README.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/README.md) lines 74-78. - **Codex CLI** must be installed globally and available on your `$PATH` to invoke the `/clone-website` skill. - The template recognizes Codex CLI as a supported platform via [`AGENTS.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/AGENTS.md) and [`README.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/README.md) lines 60-62. - No extra configuration variables or API keys are needed within the template repository itself. ## Frequently Asked Questions ### Do I need API keys to use the template with Codex CLI? No. The template itself does not require additional environment variables or secret keys. You only need Node.js 24+ and a working Codex CLI installation. Your OpenAI API keys are typically configured within the Codex CLI tool itself, not in the template configuration files. ### Can I use an older version of Node.js with this template? No. The build, lint, and type-checking scripts specifically require Node.js 24 or newer as documented in [`README.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/README.md) at lines 74-78. Using older versions will result in dependency installation failures or runtime errors during script execution. ### Where is the `/clone-website` command defined? The command is defined in [`.github/skills/clone-website/SKILL.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/.github/skills/clone-website/SKILL.md). The `scripts/sync-skills.mjs` script synchronizes this definition across all supported agents, including Codex CLI, ensuring the skill is automatically available when you start the agent. ### Why should I clone my own copy instead of the original repository? You should clone your own copy to `https://github.com//.git` rather than the original JCodesMore/ai-website-cloner-template repository to ensure you have write permissions and can customize the configuration for your specific use case without affecting the upstream template.
