- The bar starts with "Model Check:" so it is clear it comes from the browser. - "Don't show again" turns the check on opening off and says where to turn it back on; Settings → Workflows has the same switch (on by default), and turning it on checks the open workflow right away. While off, the bar never shows. - The tour's Model Check step mentions the button. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
