DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.238

Ctrl+C pauses artifact auto-replies instead of stopping them

You'll notice
Useful3 Signal3
Artifacts

Ctrl+C now pauses artifact comment auto-replies; your next message resumes them and catches up.

What

Interrupting a turn no longer tears down automatic replies to artifact comments. The watch stays connected and replies are paused until your next message, which resumes them and answers any comments that arrived in the meantime.

Details
  • The resume_replies action now lifts an interrupt pause as well as re-arming a watch that was stopped outright, and distinguishes resuming in place from resuming while the watch is still connecting.
  • Publishing that you did not ask for, such as during a wake-up or notification, leaves the pause in place; an asked-for publish or your next message lifts it.
  • Killing all agents still disarms replies for the whole session.
  • Requires comment auto-replies to be on for the session; not available in remote sessions.
Evidence

'resume_replies' re-enables automatic comment replies that were stopped or paused for the artifact at, auto-replies paused by the user's interrupt (Ctrl+C or Stop)

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