llms-full.txt is a longer companion file some sites publish alongside a short
llms.txt index: the same summary, plus selected articles, comparisons, or
guides in one plain-text document, for a client willing to fetch more than a
one-page overview.
It is not part of the original llms.txt specification. Sites that publish one
choose the format on their own. Birta publishes its own at
/llms-full.txt: the same connect instructions as our
llms.txt, plus every published guide's content in full, so an agent that
wants the whole reference gets it in one fetch.
For the short index this file expands on, see what is an llms.txt file, a real one explained line by line.
