What
When Claude works on comment threads attached to an artifact, the instructions it gets in the background now mark each thread as either "Claude: activated" or "Claude: NOT activated". Claude is told to ignore threads that are not activated.
Why
This helps stop text in threads that were never meant for Claude from steering what it does.
