Claude Code 2.1.251 now streams foreground subagent tool calls and results live to Remote Control clients, giving better visibility into background work. The /radio command is now available on Bedrock, Vertex AI, Foundry, and Claude Platform on AWS, plus when telemetry is disabled. In VSCode, the Remote Control banner moved to a footer pill that links to your session on claude.ai/code and toggles with /remote-control.
