Qué es Validador llms.txt?
llms.txt is a proposed standard file that helps large language models and AI tools discover and understand a website's key pages. It lives at /llms.txt and uses a simple Markdown-based format: an H1 title, an optional blockquote summary, sections with ## headings, and Markdown links to important pages. A validator checks that the file follows these structural rules.
Respuesta rápida
Validate your llms.txt file to ensure it follows the specification: a required H1 title, optional blockquote summary, ## section headings, and absolute Markdown links. A well-formed llms.txt helps AI tools discover and understand your site's key pages efficiently.
Limitaciones
- This validator checks structure and link format only. It does not verify that linked pages actually exist or return good content — use a link checker for that.
- The llms.txt format has no official standards body (IETF, W3C) endorsement. The specification is community-driven and may evolve over time.
- File size and link count warnings are advisory. There is no formal upper limit for llms.txt files, but shorter, curated files are more effective for AI consumption.
