> A proposed file at a site's root that lists its documents in a form built for language models to read.

## What it means in practice

It follows a published convention: a title, a summary, and sections of links, with each link pointing at a plain-text or markdown version of the page. No major engine has confirmed it uses the file for retrieval or ranking, so adopting it is a bet on convention rather than a measured tactic. Its defensible benefit is immediate and separate from search: an agent handed the file gets clean prose instead of scraped HTML. refd publishes one at /llms.txt.
