Grok Build v1.0.22 can resume finished subagents, a user reports

Grok Build v1.0.22 lets users continue a finished subagent by sending it another message, according to a user's September 7 release rundown. Background subagents also return their actual output rather than a pointer to run a tool. The shared notes describe desktop tool connections through a dedicated first-party server, a long-running workspace process that can expose folders to Computer Hub, and file-change previews that use actual file line numbers. Built-in agent tools also take priority over user-connected tools when their names collide.
