An Action Task is a predefined, trigger-based AI task that executes automatically when a specific condition is met. Rather than waiting for a human to initiate it, the system handles routine actions — like sending notifications, updating records, or launching a workflow — the moment the trigger fires.
The key difference is that an Action Task requires no back-and-forth with a user. The task is defined once, bound to a trigger, and runs on its own. Think of it as a standing instruction: when X happens, do Y — automatically, every time, without someone manually kicking it off.
