Unclear It is not stated whether supporting files are now published alongside a review page or handled somewhere else.
What
Artifacts are pages Claude can publish. Pages built with the artifact-pr-review machinery (a template for pull request reviews) no longer get special checks when published:
- The template check is gone. It used to fail with "This page carries the artifact-pr-review machinery but failed publish-time validation" and the code
pr_review_template_mismatch. - The single-file rule is gone. Publishing used to refuse with "artifact-pr-review pages are single-file: supporting files are not allowed alongside a review page (nothing was published)" when files came with a review page.
- The
composedPrReviewandpreviewOnlyoptions, which allowed mermaid diagram blocks and stamp bindings, are no longer used.composedPrReviewis no longer passed to the page renderer, andpreviewOnlyis removed from one render call. - The Artifact tool's input loses its
prReviewOnswitch and the related rules.
Why
PR-review pages are no longer checked against their template or limited to a single file when published. Together with the removed prReviewOn switch, this suggests the PR-review artifact flow was taken out or moved.
