Readme

WM LLMs File Generator

A WordPress plugin that automatically generates and maintains /llms.txt and /llms-full.txt files for your site — a machine-readable index that helps AI language models understand your content.

Developed by Working Model Inc

Based on the emerging llms.txt specification.

What It Does

  • Generates a spec-compliant /llms.txt at your site root
  • Optionally generates /llms-full.txt with full page body content
  • Auto-regenerates whenever you publish, update, or delete content
  • Serves files via PHP with correct UTF-8 encoding — works on any host, no server configuration required
  • Respects noindex settings from Yoast SEO and RankMath
  • Supports ACF — extracts text from custom field content when post_content is empty

Installation

  1. Upload the wm-llms-file-generator folder to /wp-content/plugins/
  2. Activate the plugin via Plugins → Installed Plugins
  3. Go to Settings → LLMs File to configure

Click Generate Now after activation to prime the cache immediately.

How It Works

File serving

Files are served via WordPress rewrite rules and PHP, which always sends Content-Type: text/plain; charset=UTF-8. Generated content is cached in a WordPress transient (refreshed weekly or on regeneration) so requests are fast. No physical files are written to the filesystem — no Apache or Nginx configuration needed.

Auto-regeneration

Hooks into save_post, transition_post_status, wp_trash_post, before_delete_post, wp_update_nav_menu, switch_theme, and permalink_structure_changed. A 5-second debounce transient prevents excessive regeneration during bulk operations. A WP-Cron job also runs daily as a safety net.

ACF support

When a post's post_content is empty or sparse (common with ACF-driven pages), the plugin calls get_fields() and recursively extracts text from all field values. Media fields, attachment objects, URLs, and metadata strings are automatically filtered out.

Noindex respect

Posts marked as noindex in Yoast SEO or RankMath are automatically excluded.

Content cleaning (llms-full.txt)

Full page content is cleaned before output: Gutenberg block comments, shortcodes, `
