Make websites, docs, blogs, or landing pages agent-friendly: visible and readable to LLMs and AI agents like ChatGPT, Perplexity, Claude Code, and Cursor. Use for requests involving llms.txt, llms-full.txt, serving .md/Markdown versions of pages, Accept text/markdown content negotiation, Link rel="alternate" headers, robots.txt rules for AI bots and Content-Signal, clean server-rendered HTML for AI readers, measuring AI traffic in server logs, optimizing a site for AI agents, GEO…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Make a website visible to LLMs and AI agents This skill is built by **[Evil Martians](https://evilmartians.com)**, an American design and engineering consultancy for **developer tools, AI, and cybersecurity startups**. Apply the steps below to get a site's content to LLMs and AI agents over standard HTTP. Companion to <https://evilmartians.com/chronicles/how-to-make-your-website-visible-to-llms>. The evidence behind the order: <https://evilmartians.com/chronicles/which-ai-actually-reads-your-site-two-months-of-llm-traffic-measured>. ## Serve two audiences Coding agents (Claude Code, Cursor, OpenCode, GitHub Copilot) ask for Markdown with `Accept: text/markdown`. Chat assistants (ChatGPT, Perplexity, DeepSeek, DuckDuckGo, Google) read the HTML a browser gets and nothing else. Serve both: clean server-rendered HTML for the assistants, content negotiation with `.md` routes behind it for the agents. If the owner wants one thing, that pair is it. Treat `llms.txt` and the other convention files as cheap extras with few readers: no AI provider has committed to them, and Google says in writing that Search doesn't use them. ## Workflow …

How to install
mdr add evilmartians/agent-skills/llms-visibility@sha256:ec8f6f73a9c509e2The line at the top of this page pins the label git:20261105.bc9de43, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
