While building Anima Felix, I realized @OpenAI's ChatGPT and @AnthropicAI's Claude could find the site but didn't really understand it. So I fixed that for Anima Felix first, then open sourced it as agentmarkup. It helps websites expose the signals AI agents and LLMs actually need. Available as a plugin for Next.js, Astro, and Vite. Try the checker at agentmarkup.dev to see what your site is missing.
