Discovery for agents
llms.txt
llms.txt is a plain-text file at a site's root that gives AI crawlers a curated, compact map of the most useful pages - like robots.txt, but for LLMs.
llms.txt is an emerging convention: a markdown-formatted file served at /llms.txt that points language-model crawlers at a site's most important, machine-readable content. It saves them from guessing at navigation or parsing cluttered HTML.
A companion /llms-full.txt can inline the full content in one file. Together they make a site legible to agents by intent, not by scraping.
In GraphCanon
GraphCanon publishes "/llms.txt" as an index of its markdown twins, API, and key surfaces, and "/llms-full.txt" with the whole corpus - so agents can read the graph as data.
