The main difference is -llms.txt is for reading content --while aura is for performing actions

-llms.txt tells an AI here is a clean, simple version of this page for you to read --Aura tells an AI here is a capability called create_post, it needs a title and content, and you can use it by POSTing to the /api/posts endpoint.

llms.txt is for reading, aura is for doing.

You also asked why you need npm install. You dont! To add Aura to your own website, you only need to create one static file - public/.well-known/aura.json. That's it. It s just as simple as creating a llms.txt file.

The npm install command in my project is for people who want to download and run my full reference implementation (the example server and client). It is not a requirement for the protocol itself.

And for your last question, Aura is new so no other websites are using it yet.
