WHAT IT DOES

What hydra_open_game_installer does on Hydra Bridge

AI agents invoke hydra_open_game_installer to trigger actions in Hydra Bridge. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why hydra_open_game_installer needs a policy

Opening and running a game installer executes an external process/binary on the system. This is an Execute-category action because it runs an external operation (installer) whose effects depend on the installer's contents. The blast radius is medium since it installs software but is not inherently destructive or financial.
