Asynchronous I/O

Asynchronous I/O is presented as a way to reduce latency by avoiding unnecessary serialization in real-time agents. Asynchronous I/O represents user input as incremental text updates and lets the model reason before choosing a tool call, pause, or final answer. The framework interrupts model generation when new user or tool information arrives and injects the new information into context. The system rejects invalid asynchronous behavior by injecting an error message and restarting generation.
