Mescio for Agents vs Website LLMs.txt

Mescio for Agents makes your WordPress site AI-ready by silently serving posts, pages and WooCommerce products as clean, structured Markdown to any AI agent or LLM pipeline that requests it — using the standard HTTP Accept: text/markdown content negotiation header. Human visitors using a browser are completely unaffected. Mescio for Agents only activates when an AI agent or crawler explicitly asks for Markdown. Why Markdown? Feeding raw HTML to an AI is expensive and noisy. A heading like ## About Us costs ~3 tokens in Markdown vs 12–15 tokens as HTML — before accounting for wrappers, navigation bars and script tags that carry zero semantic value. This blog post you are reading takes 16,180 tokens in HTML and 3,150 tokens in Markdown. That is an 80% reduction. Markdown has become the lingua franca for AI systems. Mescio for Agents lets your site speak it natively, at zero cost to your human visitors. How it works When an HTTP client sends a request with Accept: text/markdown, Mescio for Agents intercepts the WordPress request lifecycle before any template is rendered, converts the post content to clean Markdown, and returns it with the correct Content-Type: text/markdown header. curl https://yoursite.com/your-post/ \ -H "Accept: text/markdown" Features Zero configuration — works out of the box on any singular post, page or custom post type /llms.txt endpoint — auto-generated index of all your content in the llmstxt.org standard format, so AI agents can discover what’s on your site /llms-full.txt endpoint — full site content in a single Markdown file, ready for RAG pipelines WooCommerce support — product pages include price, SKU, stock status, rating, attributes and gallery; products are grouped by category in llms.txt YAML front matter — every document includes structured metadata (title, description, URL, date, categories, tags, featured image) Multilingual — detects language via WPML, Polylang, TranslatePress or WordPress locale; emits Content-Language and Link: rel=alternate headers REST API endpoint — /wp-json/mescio-for-agents/v1/markdown?id= or ?url= Page builder cleanup — aggressively strips Elementor, Divi, WPBakery and Beaver Builder layout noise Token count header — X-Markdown-Tokens tells AI pipelines how large the document is before processing Content Signals — emits Content-Signal: ai-train=yes, search=yes, ai-input=yes Correct HTTP caching — Vary: Accept ensures CDNs cache HTML and Markdown versions separately Response headers Content-Type: text/markdown; charset=utf-8 Content-Language: it (or detected language) Vary: Accept X-Markdown-Tokens: 725 Content-Signal: ai-train=yes, search=yes, ai-input=yes Link: ; rel="alternate"; hreflang="en" (when translations available) Multilingual plugin support WPML — reads language and available translations automatically Polylang — reads language and links to translated post IDs TranslatePress — reads trp_language post meta Manual — configure primary language and additional languages in Settings → Mescio for Agents REST API GET /wp-json/mescio-for-agents/v1/markdown?id=42 GET /wp-json/mescio-for-agents/v1/markdown?url=https://yoursite.com/my-page/ Developer hooks Filter: mescio_enabled_post_types — add or remove post types dynamically.

Website LLMs.txt generates and manages an llms.txt file, a structured, AI-ready index that helps large language models like ChatGPT, Claude, and Perplexity understand your site’s most important content. How llms.txt works Traditional sitemaps and robots files guide search engines. But as AI-driven systems such as ChatGPT, Claude, and Perplexity increasingly ingest web content, they benefit from a clear, structured list of a site’s most important URLs. llms.txt offers that: a plain-text or Markdown list of essential public URLs, optionally annotated with titles, descriptions, and grouping, designed for AI consumption rather than general web crawling. Key benefits ✅ AI discovery readiness: future-proof your site for AI indexing and content retrieval. ✅ Fully automatic: the plugin builds and updates your llms.txt file on its own schedule. ✅ SEO plugin integration: works seamlessly with Yoast SEO, Rank Math, SEOPress, and AIOSEO, automatically excluding content marked as noindex or nofollow. ✅ Advanced controls: choose post types, customize file titles or descriptions, attach optional Markdown files, and trigger manual regeneration. ✅ Developer-friendly: includes filters such as llms_generator_get_post_meta_description for description logic, performance tuning, and custom indexing behavior. ✅ WooCommerce & multisite ready: respects product visibility rules and scales easily across large or networked sites. Activation & setup Activate the plugin. Visit Settings → LLMs.txt to configure post types and update frequency (immediate, daily, or weekly).
