Claude Code v2.1.233

Automatic comment replies stand down if someone else answers first

Not switched on
Useful2 Signal4
Artifacts Notable not in their notes

Claude withholds an automatic artifact comment reply if someone else answered while it was writing.

Comment auto-reply stand-down is present but off unless CLAUDE_CODE_ARTIFACT_COMMENTS_AUTOREACT is set, or the tengu_sorrel_trellis flag turns on.

Feature flag
tengu_sorrel_trellis On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.233. It isn't a statement about your account. What a flag value here can and cannot tell you

CLAUDE_CODE_ARTIFACT_COMMENTS_AUTOREACT
What

Before posting an automatic reply to an artifact comment, Claude Code re-reads the thread and, if a reply it does not recognise as its own arrived while it was composing, withholds its own reply and reports that the comment was answered while the reply was being written. Off unless CLAUDE_CODE_ARTIFACT_COMMENTS_AUTOREACT is set; otherwise it follows the tengu_sorrel_trellis flag, which is off by default.

Details
  • Produces a distinct outcome, answered_post_time, with its own telemetry values.
  • The notice shown to Claude explains why the reply was held back.
Evidence

answered_post_time

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