Copy this loadout

Prompt for Codex

Paste this into Codex. It installs each spell, leaves API keys and sign-ins to you, and ends with the command that restarts it with this weapon and charge.

Set up these tools for me in Codex.
Loadout: https://vibe-rpg-simulator.vercel.app/loadouts/expo-store-release/

1. Expo Overview

How to do it:
- Skip anything that is already installed. Run the rest in order and check that each step worked.
- Never ask me to paste an API key or token into this chat. When a command needs one, such as YOUR_API_KEY, give me the full command to run in my own terminal.
- Ask me for any other value you can't work out, such as a project path.
- If a command asks a question or needs a browser sign-in or an open app, tell me what to do and wait.
- If a command fails, follow the install steps in the tool's source for Codex instead. Show me any command that is not on this list before you run it, and install nothing else.

When you're done, tell me what is ready and what still needs me. New tools load in a new session, so finish by telling me to restart Codex with GPT-6.1 Sol and reasoning effort medium:
codex --model gpt-6.1-sol --config model_reasoning_effort='"medium"'

Terminal commands

Or paste these lines into a terminal. The first part installs every spell for Codex; the last line starts it with the same weapon and charge. Lines starting with # are notes or commands you type inside the agent.
