Coati OS Wants the Agent to Be the Phone

Field notes

Coati describes a layered execution engine that prefers structured or system-level actions, then falls back to visual interaction and simulated input. Its stated validation includes 43 robustness assertions, 308 unit tests, 11 of 11 applications running in the background, and three isolated background spaces operating concurrently. The page identifies the Android app as an upcoming open-source release and the ROM as a separate development track, so the documented architecture is more immediately available than the finished operating system.
