HarmonyOS

A general-purpose agent writing ArkTS will crash and burn, for exactly three reasons. It does not know ArkTS decorators or build commands; it has no official docs to look things up in, so it invents APIs from memory; and even when the code is right, it has no idea how to build the package, install it on a device, and ship it to the app store.
