## Command Usage Guidelines

### How to Invoke Commands

Commands are invoked using the slash syntax in Claude Code:

```bash
/developer-kit-java:devkit.java.{command-name} [arguments]
```

### Best Practices

1. **Read command docs first**: Each command has detailed documentation
2. **Provide clear context**: Give commands the information they need
3. **Review output**: Commands generate suggestions you should review
4. **Iterate**: Use command output as starting point, refine as needed
5. **Test thoroughly**: Especially for refactoring and dependency upgrades
