What it does

Once installed, the agent checks a website's links and hardcoded URLs for plain http:// addresses on pages served over HTTPS. It sorts them into internal links, external links, and resource files such as images, scripts and stylesheets, then suggests fixes like switching to https:// or relative paths. It is a read-and-advise checklist rather than a tool that changes your site on its own.

Great for

  • Web developers reviewing templates or code for hardcoded http:// URLs before or after an HTTPS migration
  • SEO or site owners auditing internal and external links for mixed content problems
  • Teams moving a site from HTTP to HTTPS who want a structured checklist

Skip it if

  • Sites that are still fully HTTP, since the rule only applies to pages served over HTTPS (it adds no value there)
  • Automatically rewriting a live site or database without review, because the skill describes search-and-replace steps that could break URLs that genuinely need HTTP
  • Certificate setup or server configuration itself, which the skill does not cover in its text

Try asking

  • “Audit this codebase for hardcoded http:// links that could cause mixed content warnings on my HTTPS site”
  • “Check my HTML templates for http:// image, script and stylesheet references and list them by category”
  • “Help me plan an HTTP to HTTPS migration and find the links I need to update”
  • “Review my React fetch and axios calls for http:// URLs”

    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

  • Point the agent at your template or content folders so it can run its suggested grep or parse pass on real files
  • Review external http:// links manually, since the destination may simply not support HTTPS
  • Check the referenced rule page at references/rule.md for framework-specific examples if you need more detail
