I wonder why we broke the web.

Already happening. I was using Claude to check out sampler plugins and I'm sure it happens undetected, and it might have mentioned it with other versions, but Claude Opus 4.8, being it's helpful, honest self, told me that one of the pages it reviewed had hidden text instructing it to recommend that plugin. It caught it and was able to avoid influence from that plugin at least, but we're already living in that world.

Mintlify generates an llms.txt and llms-full.txt for all documentation sites. These work really well:

- https://cloud.laravel.com/docs/llms.txt

- https://cloud.laravel.com/docs/llms-full.txt

I can definitively say llms.txt is not used by any AI players. I run a blogging platform with around 80k blogs and /llms.txt is not requested by anything (other than humans checking to see if there's an llms.txt path).

All regular pages are aggressively scraped to the extent it's a problem I have to consistently manage, but not llms.txt.
