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 v2.1.228 11 Aug 2026

Repeated artifact auto-reply notices collapse into one line

You'll notice

Useful3 Signal2

Artifacts

Repeated auto-replies to one artifact now show a single summary line naming that artifact.

What

When Claude auto-replies to the same artifact several times, you now get a single summary line naming that artifact instead of a generic "tasks completed" rollup.

Details

The auto-reply notice carries a grouping key made of the family name auto-replied plus the artifact name and thread id, so only notices for the same artifact merge.
Detail text is preserved alongside the grouping key.

Evidence

more auto-reply

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