This site has a useful foundation, but important gaps still limit AI readability.
Key strengths include AI guidance file and sitemap, while plain-text page access and content signals need attention.
Recommended next step
add content negotiation for Accept: text/markdown on the homepage and return a markdown representation with Content-Type: text/markdown.
Keep the HTML response for regular browser requests.

Next step: Review AI crawler Disallow rules and keep only the paths that should be excluded from AI crawler access; serve a non-empty HTML homepage with a canonical link tag.robots.txt contains AI-crawler path blocks for GPTBot, ChatGPT-User, ClaudeBot, Claude-Web, PerplexityBot, and Google-Extended.

The sitemap.xml file is valid and contains URL entries.

Evidence
The homepage returned HTML when requested with Accept: text/markdown, so the server appears to ignore markdown content negotiation.

Next step: Add content negotiation for Accept: text/markdown on the homepage and return a markdown representation with Content-Type: text/markdown. Keep the HTML response for regular browser requests.The homepage has some semantic HTML signals, but one or more title, metadata, heading, landmark, content, or link text checks need improvement.

Next step: Add the standard directive 'Content-Signal: ai-train=no, search=yes, ai-input=yes' to robots.txt, HTML metadata, or HTTP headers so AI systems can discover content usage preferences.// generated fixes
