 Important Workflows:
 
 Script Management:
-1. After creating or modifying scripts with `manage_script`, ALWAYS call `reload_domain` immediately
-2. Wait for Unity to recompile (domain reload is asynchronous)
-3. Use `read_console` to check for compilation errors before proceeding
-4. Only after successful compilation can new components/types be used
