To contribute additional features or improvements: 1. **Enhancement suggestions**: Open an issue to discuss new features or command improvements 2. **Bug fixes**: Create a new command class inheriting from `Command` 3. **New commands**: Implement additional refactoring logic using Roslyn APIs 4. **Testing**: Register the command in `Program.cs` and add comprehensive tests in `Cast.Tool.Tests` +5. **MCP Integration**: New commands are automatically exposed via the MCP server The established pattern makes it straightforward to add specialized refactoring operations for specific use cases or domain-specific transformations.
