llms.txt
A root-level file that tells language models which content to prioritise.

Definition
llms.txt is a proposed plain-text file placed at the root of a domain that lists the canonical, high-value documents a language model should read when summarising the site.
It complements robots.txt: robots.txt governs access, llms.txt suggests priority and provides curated context.
Why it matters
Retrieval systems must choose a small subset of a site to read. A curated index reduces the chance they summarise from thin or outdated pages.
How to apply it
- List canonical product, pricing and documentation URLs with one-line descriptions.
- Keep it under a few dozen entries and regenerate it when key pages change.
- Do not treat it as an access control mechanism.
