1. Type: \`/gemini-function\`
2. Enter: "email validation with project's existing validation patterns"
3. Gets: Function that matches your existing code style and dependencies

### Project-Wide Security Audit
1. Type: \`/gemini-audit\`
2. Gets: Comprehensive security analysis of all source files, configs, and dependencies

## 🛠️ Pro Tips

- **File Context**: Commands automatically include relevant files (@package.json, @configs, etc.)
- **Project Awareness**: All commands consider your tech stack and dependencies
- **Smart Selection**: Use @src/* for project-wide analysis, @{currentFile} for specific files
- **Sandbox Safety**: Function generation uses safe sandbox environment
- **Multi-file Analysis**: Advanced commands can analyze entire project structure

## 🆘 Troubleshooting

- **Commands not showing?** Restart Claude Code after setup
- **MCP server issues?** Verify: \`claude mcp list\` shows gemini-cli
- **Authentication issues?** Run: \`gemini auth\` to re-authenticate
- **File not found errors?** MCP automatically handles missing files gracefully

## 🔗 MCP Integration Benefits

- ✅ **Native Claude Code integration** - No bash dependencies
- ✅ **File-aware analysis** - Automatic @filename context inclusion  
- ✅ **Large context windows** - Leverage Gemini's full capabilities
- ✅ **Sandbox safety** - Secure code generation and testing
- ✅ **Project intelligence** - Understands your entire codebase
- ✅ **Dependency awareness** - Considers package.json and configs

Happy coding with next-generation AI assistance! 🎉
