Date and method
Run 2026-11-02T11:16:54Z UTC, one request set per site: home page, robots.txt, llms.txt, sitemap, up to 3 sign-up/login/contact links and /.well-known agent cards. Our agent names itself TuperAgentCheck-bot, never submits a form and never solves a captcha. Score: Access 45, Discovery 25, Understanding 20, Agent tools 10. This page shows the stored run and is not re-scored by hand; a rate limit or busy server is shown as "could not read". The site may have changed since. Raw data: data.json. Wrong? Mail support@tuper.app and we re-run it.
