+
+Create a new React component named $ARGUMENTS with TypeScript support.
+Include proper typing and basic structure.

+Commands run in your project's root directory and their output becomes part of the prompt.
+
+---
+
+## Reference files
+
+Include files in your command using `@` followed by the filename.

+Review the component in @src/components/Button.tsx.
+Check for performance issues and suggest improvements.

+## Command directory
+
+Store command files in these locations:
+
+- `.opencode/command/` - Project-specific commands
+- `command/` - Global commands in config directory
+
+Project commands take precedence over global ones.
+

+
+- `/init` - Initialize project and create AGENTS.md
+- `/undo` - Revert the last changes
+- `/redo` - Restore reverted changes
+- `/share` - Share the current conversation
+- `/help` - Show available commands and keybinds
+
+Use `/help` to see all available commands in your setup.
