llms.txt files have nothing to do with crawlers or big LLM companies. They are for individual client agents to use. I have my clients set up to always use them when they’re available, and since I did that they’ve been way faster and more token efficient when using sites that have llms.txt files.

So I can absolutely assure you that LLM clients are reading them, because I use that myself every day.

Thanks for the clarification.

>for use in LLMs such as Claude (1)

From your website, it seems to me that LLMs.txt is addressed to all LLMs such as Claude, not just 'individual client agents' . Claude never touched LLMs.txt on my servers, hence the confusion.
