llms.txt in Different Domains

This page has some guidelines and suggestions for how different domains could utilize llms.txt to allow LLMs to better interface with their site if they so choose.

Remember, when constructing your llms.txt you should “use concise, clear language. When linking to resources, include brief, informative descriptions. Avoid ambiguous terms or unexplained jargon.” Additionally, the best way to determine if your llms.txt works well with LLMs is to test it with them! Here is a minimal way to test Anthropic’s Claude against your llms.txt:

# /// script
# requires-python = ">=3.8"
# dependencies = [
#     "claudette",
#     "llms-txt",
#     "requests",
# ]
# ///
from claudette import *
from llms_txt import create_ctx

import requests

model = models[1] # Sonnet 3.5
chat = Chat(model, sp="""You are a helpful and concise assistant.""")

url = 'your_url/llms.txt'
text = requests.get(url).text
llm_ctx = create_ctx(text)
chat(llm_ctx + '\n\nThe above is necessary context for the conversation.')

while True:
    msg = input('Your question about the site: ')
    res = chat(msg)
    print('From Claude:', contents(res))

The above script utilizes the relatively new uv syntax for python scripts. If you install uv, you can simply run the above script with uv run test_llms_txt.py and it will handle installing the necessary library dependencies in an isolated python environment. Else you can install the requirements manually and run it like any ordinary python script with python test_llms_txt.py.

Restaurants

Here is an example llms.txt that a restaurant could construct for consumption by LLMs:
