llms.txt vs llms-full.txt: What You Actually Need (Industry Confusion Explained)
llms.txt vs llms-full.txt: What You Actually Need (Industry Confusion Explained)
There's growing confusion in the AI community about llms-full.txt files. Website owners are asking: "Do I need both llms.txt AND llms-full.txt?" The short answer is no - and this article will explain why.
The Truth About llms-full.txt
llms-full.txt is NOT an industry standard. It's a processed derivative file created by specific tools, not something websites should publish directly.
What llms-full.txt Actually Is
According to the official llms.txt specification from llmstxt.org, llms-full.txt (or llms-ctx-full.txt) is:
- A tool-generated file created by processing the original llms.txt
- An expanded version that includes content from all URLs referenced in llms.txt
- Used internally by projects like FastHTML for their own tooling
- Not part of the official specification
The Official Standard: Just llms.txt
The industry standard requires only:
- Standard llms.txt file at `/llms.txt`
- Markdown format with specific structure
- Optional .md versions of existing pages (e.g., `page.html.md`)
Why the Confusion Exists
Tool-Specific Implementations
Some projects create expanded versions for internal use:
# FastHTML project creates:
llms-ctx.txt # Without optional URLs
llms-ctx-full.txt # With all referenced URLs expanded
These are processing artifacts, not standards that websites need to implement.
Competitor Complexity
Some llms.txt repositories require:
- GitHub workflows - creating barriers for non-developers
- Complex submission processes - confusing users
- Multiple file variants - unnecessary complexity
This complexity makes people think they need more than the simple standard.
What Website Owners Actually Need
1. Just Create llms.txt
Place a single file at your website root:
# Your website: https://example.com/llms.txt
# Example Company
> AI training guidelines for our website content
## Documentation
- [API Docs](https://example.com/docs): Technical documentation
- [Blog Posts](https://example.com/blog): Company insights and tutorials
## Optional
- [Legal Pages](https://example.com/legal): Terms and privacy policy
2. Follow the Official Format
The llms.txt specification requires:
- H1 header with site/project name
- Blockquote with brief description
- H2 sections with markdown lists of URLs
- Optional section for secondary content
3. That's It!
You don't need:
- ❌ llms-full.txt files
- ❌ GitHub repositories
- ❌ Complex build processes
- ❌ Multiple file variants
