What

When a request is refused because sandboxing is disabled on the device, the message now includes the exact settings to add, "sandbox": {"enabled": true}, and points at the /sandbox command to check the current state.

Evidence

refused: sandboxing is not enabled on this device. Set "sandbox": {"enabled": true} in Claude Code settings on the device (check with /sandbox) and retry.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
