llms.txt is a proposed standard for websites to provide LLM-friendly content at a well-known URL. Instead of forcing AI agents to parse HTML, sites serve a structured markdown file with their key documentation, APIs, and resources — making it trivial for agents to understand what a site offers.
Think of it like robots.txt but for helping AI agents, not restricting them.
