WHAT IT DOES

What set-air-landing does on Defcon

AI agents invoke set-air-landing to trigger actions in Defcon. 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 set-air-landing needs a policy

This tool issues a command to the game engine to change the state of an air unit by designating a landing target. It is an operational game command (Execute category) that causes an external system (the DEFCON game) to perform an action. While it doesn't delete data or move money, it has real gameplay consequences within the simulation.
