A widely shared r/LocalLLaMA post from a former Manus backend lead argues that a single run(command="...") interface often beats a catalog of typed function calls for agents. The post ties Unix text streams to token-based model interfaces, then backs the claim with design patterns around piping, progressive help, stderr visibility, and overflow handling.
