A Field Guide to llms.txt

Field notes

LLMS-Explorer treats documentation as both subject and test material. It presents a concept tree alongside a three-dimensional graph, mirrors llms-full.txt files in a directory, and grades them from A to F with llms_lint. A recorded demo compares keyword, vector, and hybrid retrieval over one document set. The project also exposes Markdown twins for its pages and publishes an llms.txt family for crawlers or agents, while account-based API keys and usage sit behind sign-in.
