LLMS Full.txt Guide for Big Sites
A short llms.txt file is best for the main map; large sites can link to llms-full.txt for the complete page index.
Short answer
Use llms-full.txt when a site has many indexable pages that are too numerous for the root llms.txt summary. The root file should link to the full index, while llms-full.txt can list every canonical tool, guide, state page, or programmatic page you want answer engines to discover.
