 - **Commands**: Register new commands in `package.json` and implement them in `src/commands.ts` or a relevant module.
 - **Logging**: Use the `Logger` utility for all logging purposes. Don't use console.log or similar methods directly.
 
+## Specific Feature Practices
+- **Commands**: When adding a new command, consider whether it should be available in the command palette, context menus, or both. Add the appropriate menu entries in `package.json` to ensure the command is properly included, or excluded (command palette), from menus.
