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.

Auto-react posts explicit notices when it stands down

Not switched on
Useful2 Signal3
Artifacts

When auto-reply to artifact comments stands down, Claude now tells you once why instead of staying silent.

Auto-reply suppression notices exist behind the artifact auto-react gate, which is off by default.

What

Instead of silently doing nothing, the scanner posts a one-time in-session notice per artifact explaining why auto-reply is suppressed.

Details
  • covers plan mode, the hourly cap being reached, and a permission mode that only allows notification
  • also covers repeated denials from a permission hook or content gate, which pauses affected threads until a successful auto-reply elsewhere on the same artifact
  • behind the auto-react gate
Evidence

auto-reply is paused while in plan mode; use the Artifact tool to read and reply.

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