            Your account has been [automatically flagged](https://agentscan.tools/user/${{ github.event.pull_request.user.login }}) as likely to be created by a bot, LLM, or agent,
            and will be automatically closed. If you believe this is a mistake, please reply to this comment and we will review it.
