New built-in prompts tell Claude how to resume after hitting the output limit or being cut off mid-response
What
Three new hardcoded instruction strings were added that tell Claude how to resume its response after specific interruptions: hitting the output token limit, and being cut off mid-stream, including a separate variant for when only the next message (not the full prior context) is delivered to it.
Why
This should make Claude's resumed responses after an interruption more consistent, since it now has explicit instructions for picking back up rather than improvising.
