What
The Artifact tool now explains why a reply could not be posted instead of implying the thread state was the cause.
Details
- Both the reply failure text and the action description were rewritten.
- The new wording states that activation is per artifact version and can be cleared by deactivation, republish or rename.
- It states plainly that this is unrelated to whether a thread is resolved.
- It instructs Claude not to assert a specific reason for the failure.
Evidence
resolved threads still accept replies
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
