+# Installing MiniMax Skills for OpenCode
+
+## Prerequisites
+
+- [OpenCode.ai](https://opencode.ai) installed
+
+## Installation
+
+Add minimax-skills to the `plugin` array in your `opencode.json` (global or project-level):
+
+```json
+{
+  "plugin": ["minimax-skills@git+https://github.com/MiniMax-AI/skills.git"]
+}
+```
+
+Restart OpenCode. That's it — the plugin auto-installs and registers all skills.
+
+Verify by asking: "List available skills"
+
+## Available Skills
+
+- **frontend-dev** — Frontend development with UI design, animations, AI-generated media assets
+- **fullstack-dev** — Full-stack backend architecture and frontend-backend integration
+- **android-native-dev** — Android native application development with Material Design 3
+
+## Usage
+
+Use OpenCode's native `skill` tool:
+
+```
+use skill tool to list skills
+use skill tool to load minimax-skills/frontend-dev
+```
+
+## Updating
+
+MiniMax Skills updates automatically when you restart OpenCode.
+
+To pin a specific version:
+
+```json
+{
+  "plugin": ["minimax-skills@git+https://github.com/MiniMax-AI/skills.git#v1.0.0"]
+}
+```
+
+## Troubleshooting
+
+### Plugin not loading
+
+1. Check logs: `opencode run --print-logs "hello" 2>&1 | grep -i minimax`
+2. Verify the plugin line in your `opencode.json`
+3. Make sure you're running a recent version of OpenCode
+
+### Skills not found
+
+1. Use `skill` tool to list what's discovered
+2. Check that the plugin is loading (see above)
+
+### Tool mapping
+
+When skills reference Claude Code tools:
+- `TodoWrite` → `todowrite`
+- `Task` with subagents → `@mention` syntax
+- `Skill` tool → OpenCode's native `skill` tool
+- File operations → your native tools
