SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires requests, bs4, and includes scripts (resource) components.

What problem does it solve?

llms.txt provides a simple, machine-readable method for summarizing a site's structure and key content so AI systems can quickly understand what to read or cite, reducing unnecessary crawling and misinterpretation.

Core Features & Use Cases

Validate an existing llms.txt for correctness, including title, description, sections, and absolute URLs.
Generate a concise llms.txt and a detailed llms-full.txt by crawling the site and extracting page-level descriptions.
Produce a consistent, reference-ready document that can be reviewed by humans and loaded by AI agents to guide content understanding.

Quick Start

Run the generator against your site to produce initial llms.txt and llms-full.txt, then review and refine the sections.

FAQPage Schema

How do I generate an llms.txt file to summarize my website for AI crawling?▼

To generate an llms.txt file, you crawl the site to extract page-level descriptions and summarize the structure into absolute URLs and sections. This produces a concise llms.txt and a detailed llms-full.txt to guide AI comprehension and citation.

What is the best way to validate an existing llms.txt file for AI site understanding?▼

Validating an llms.txt file involves checking its title, description, sections, and absolute URLs for correctness. This ensures the document is machine-readable and reference-ready before being loaded by AI agents to guide content retrieval.

Do I need a detailed llms-full.txt if my website has dynamic content and multiple sections?▼

Yes, for sites with varied navigation and dynamic content, generating a detailed llms-full.txt is recommended alongside the concise version. It provides deeper page-level descriptions to improve AI comprehension and reduce misinterpretation.

Can I use Python requests and bs4 to crawl and build an llms.txt file?▼

Yes, the generation process uses Python requests and bs4 to crawl web pages and extract content structures. These dependencies parse the site elements to build a consistent, reference-ready llms.txt document.

Why does my llms.txt validation fail when using relative URLs?▼

llms.txt validation fails with relative URLs because the standard requires absolute URLs to ensure AI systems can directly access and cite the content. The generator extracts and formats all links as absolute paths to prevent retrieval errors.

When should I not use automated llms.txt generation for my site structure?▼

You should avoid automated generation for extremely small single-page sites with no dynamic content, as manual creation is faster. The tool targets sites with varied navigation and multiple sections needing structured AI comprehension.
