What probably matters to youSection of the release
A new "check" artifact addon tool (addon: "check") offers local page preview plus runtime diagnostics for viewers, described as letting you "preview a page locally and read viewers' runtime diagnostics." It's added to the addon list alongside the existing comments and data artifact addons, but only exposed when either CLAUDE_CODE_ARTIFACT_VERIFY (or the tengu_osier_pylon_trace gate) or CLAUDE_CODE_ARTIFACT_PREVIEW (or the tengu_cobalt_plinth_aspen gate) is enabled. The verify path is forced off whenever CLAUDE_CODE_REMOTE is set, and the preview path additionally requires a headless-Chrome finder module to be compiled into the build, otherwise it throws "artifact preview is not compiled into this build." All paths are off by default.
