WHAT IT DOES

What install_loenn_manager does on Loenn

WHY IT NEEDS A POLICY

Why install_loenn_manager needs a policy

The name strongly implies installing software or a manager component, which would constitute executing an external operation with potentially broad system effects. However, with no description available, confidence is low. Installation operations typically fall under Execute as they run processes and modify system state, warranting a high severity due to the potential blast radius of installing unintended software.

From the tool's definition Tool name 'install_loenn_manager' — the word 'install' implies executing an installation process, but the description is empty and uninformative.
