What
In artifacts, resolving a comment thread now follows the same rule as replying: it only works on threads a person explicitly activated for Claude. Claude is told to report what it did and leave the thread for the commenter rather than resolving one marked as not activated, even if it addressed the feedback.
Details
- The per-thread status line was reworded from "Claude replies: NOT activated" to spell out that Claude can neither reply nor resolve.
- Applies only in sessions where the comment verbs are present in the tool schema.
- Automatic-reply failures gained two more outcomes, a withheld full rewrite and a timeout, each with its own message posted to the thread and shown in the session.
- Reply composition failures are now reported distinctly: truncated (with a flag for empty output), empty, and errored.
Evidence
Resolve, like reply, works only on threads activated for Claude, never call resolve on a thread marked NOT activated, Resolve, like reply, works only on threads activated for Claude: never call resolve on a thread marked NOT activated
