What it does

When installed, the agent can review a website or web app to check that every page loads over secure HTTPS, that the TLS certificate is valid and covers all hostnames including www, and that plain HTTP requests permanently redirect (301) to HTTPS. It can also explain why this matters and walk through obtaining a free certificate, such as from Let's Encrypt, and configuring the server. It is a checklist-style guide built from a web development rule, not a scanner that runs by itself.

Great for

  • Web developers who want an agent to review HTTPS setup and redirects
  • Site owners preparing for a security audit or launch
  • Students learning why HTTPS matters and how certificates are configured

Skip it if

  • Automated security scanning of third-party sites without permission, since the skill itself only guides the agent and does not define authorized testing scope
  • Replacing a professional penetration test for high-stakes systems, because the guidance is general and does not cover full TLS configuration review

Try asking

  • “Audit my site example.com to check whether all pages are served over HTTPS with a valid certificate.”
  • “Check that my HTTP requests redirect to HTTPS with a 301 status code.”
  • “Explain how to get a free Let's Encrypt certificate and configure Nginx to redirect HTTP to HTTPS.”
  • “Review my server config for HTTPS issues and flag any mixed content or cookie problems.”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give the agent the exact domain or server config so it can check real responses rather than guessing.
  • Ask it to verify results with SSL Labs (ssllabs.com/ssltest) and aim for an A or A+ grade.
  • Only point the agent at websites you own or have permission to test.
