Is llms.txt really useful?

[simplylizz]

I've heard a lot of skepticism about llms.txt, for example:

• https://medium.com/@kaispriestersbach/the-llms-txt-is-dead-more-precisely-a-dud-ab7bee4f469c
• https://www.reddit.com/r/seogrowth/comments/1rmlx4b/llmstxt_is_freaking_bs_and_nobody_needs_it/

Is there any evidence that it’s actually crawled by AI crawlers? This skill checks for it, but does that really make sense?

llms.txt is like a road sign: many find it useless, yet no one dares to to take it down..
