+# Installing MiniMax Skills for Codex
+
+Enable MiniMax skills in Codex via native skill discovery. Just clone and symlink.
+
+## Prerequisites
+
+- Git
+
+## Installation
+
+1. **Clone the repository:**
+   ```bash
+   git clone https://github.com/MiniMax-AI/skills.git ~/.codex/minimax-skills
+   ```
+
+2. **Create the skills symlink:**
+   ```bash
+   mkdir -p ~/.agents/skills
+   ln -s ~/.codex/minimax-skills/skills ~/.agents/skills/minimax-skills
+   ```
+
+   **Windows (PowerShell):**
+   ```powershell
+   New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.agents\skills"
+   cmd /c mklink /J "$env:USERPROFILE\.agents\skills\minimax-skills" "$env:USERPROFILE\.codex\minimax-skills\skills"
+   ```
+
+3. **Restart Codex** (quit and relaunch the CLI) to discover the skills.
+
+## Available Skills
+
+- **frontend-dev** — Frontend development with UI design, animations, AI-generated media assets

+
+## Verify

+
+```bash
+cd ~/.codex/minimax-skills && git pull

+
+Skills update instantly through the symlink.
