> llms.txt content quality is how useful that file is to an AI model: a clear description of the site, working links to its sections and enough detail.

## Why it matters

Having an empty or minimal llms.txt is not enough. AI models need quality content: a website description, links to key sections, .md versions of documentation. A high-quality llms.txt significantly improves the accuracy of AI responses about your site.

## In practice

OpenAI has a detailed overview at developers.openai.com/api/docs/llms.txt with links to all API sections including .md versions. A low-quality llms.txt with a single line 'This is our website' barely helps AI models at all.

## How be1st checks it

Evaluates the content quality of the /llms.txt file: length, website description, number of section links, presence of .md links, and overall informativeness. The quality score (0-100) is used directly and the check passes from 80. If llms.txt doesn't exist (A6=fail), this check is automatically N/A.
