What
When an agent Claude started finishes a task, Claude Code sends Claude a notice with the result. These notices now:
can carry a note from whoever started the task, added to the end of the notice
warn that the result may relay text marked as coming from a Remote Control session on another device, and that this text should be treated as data, not instructions
Before, the only relay warning was about Artifact content.
Why
This helps stop text from another device being read as commands to Claude, a kind of attack known as prompt injection.
