What

Claude Code has a new switch that Anthropic controls remotely. It is off unless it is switched on remotely. It can be set to apply:

  • everywhere
  • only in hosted use, and only when Cowork is in use
Why

This is a feature present in the code but not yet switched on by default, and it is tied to Cowork.
