Botkibble vs Kolibia Agent-Ready

AI agents, LLMs, and crawlers have to wade through navigation bars, sidebars, ads, and comment forms to reach the content they want, and every element costs tokens. Cloudflare measured an 80% reduction in token usage when converting a blog post from HTML to Markdown (16,180 tokens down to 3,150). Botkibble adds a Markdown endpoint to every published post and page. Cloudflare offers Markdown for Agents at the CDN edge on Pro, Business, and Enterprise plans. Botkibble does the same thing (for free) at the origin, so it works on any host. GitHub Repository Three ways to request Markdown: .md suffix: append .md to any post or page URL (e.g. example.com/my-post.md) Query parameter: add ?format=markdown to any post or page URL Content negotiation: send Accept: text/markdown in the request header What’s in every response: Structured metadata header with title, date, categories, tags, word count, character count, and estimated token count (in YAML frontmatter format, readable by any AI agent) Clean Markdown converted from fully-rendered post HTML (shortcodes run, filters applied) Content-Type: text/markdown and Vary: Accept response headers Content-Signal header for AI signal declaration — defaults to ai-train=no, search=yes, ai-input=yes — see contentsignals.org X-Markdown-Tokens header with estimated token count Discovery via in the HTML head and Link HTTP header Automatic cache invalidation when a post is updated or deleted Performance: Botkibble writes Markdown to disk on the first request, then serves it as a static file. A built-in Fast-Path serves cached files during WordPress’s init hook, before the main database query runs. No extra configuration needed. Add a web server rewrite rule and Botkibble bypasses PHP entirely, serving .md files the same way a server would serve an image or CSS file: Method Avg. response time Standard HTML 0.97s Markdown (cold, first request) 0.95s Markdown (cached, PHP Fast-Path) 0.87s Markdown (Nginx/Apache direct) 0.11s Serving directly from disk is 88% faster than a full WordPress page load. See the Performance section below for Nginx and Apache configuration. Security: Drafts, private posts, and password-protected content return 403 Forbidden Rate limits cache-miss regenerations (20/min by default) to mitigate DoS abuse X-Robots-Tag: noindex keeps Markdown versions out of search results Link: rel="canonical" points search engines back to the HTML version Cache variants (optional): You can persist alternate cached representations by adding ?botkibble_variant=slim (or any other variant name). Variant caches are stored under: /wp-content/uploads/botkibble/_v/ / .md What it does NOT do: Expose drafts, private posts, or password-protected content Serve non-post/page content types by default Require any configuration. Activate and it works. Why Markdown? HTML is expensive for AI systems to process. Cloudflare measured an 80% reduction in token usage when converting a blog post from HTML to Markdown (16,180 tokens down to 3,150). Cloudflare now offers Markdown for Agents at the CDN edge via the Accept: text/markdown header, available on Pro, Business, and Enterprise plans. This plugin does the same thing at the origin, so it works on any host. It also adds .md suffix URLs, ?format=markdown query parameters, YAML frontmatter, static file caching, and server-level offloading. If you use Cloudflare, both share the same Accept: text/markdown header, Content-Signal headers, and X-Markdown-Tokens response headers. Cloudflare currently defaults to Content-Signal: ai-train=yes, search=yes, ai-input=yes with no way to change it. Botkibble defaults to ai-train=no and lets you override the full signal per site via the botkibble_content_signal filter. Performance & Static Offloading This plugin supports static file offloading by writing Markdown content to /wp-content/uploads/botkibble/. Nginx Configuration To bypass PHP entirely and have Nginx serve the files (including variants) directly: # Variants location ~* ^/(_v/[^/]+/.+)\.md$ { default_type text/markdown; try_files /wp-content/uploads/botkibble/$1.md /index.php?$args; } # Default location ~* ^/(.+)\.md$ { default_type text/markdown; try_files /wp-content/uploads/botkibble/$1.md /index.php?$args; } Apache (.htaccess) Add this to your .htaccess before the WordPress rules: RewriteEngine On # Variants RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads/botkibble/_v/$1/$2.md -f RewriteRule ^_v/([^/]+)/(.+)\.md$ /wp-content/uploads/botkibble/_v/$1/$2.md [L,T=text/markdown] # Default RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads/botkibble/$1.md -f RewriteRule ^(.*)\.md$ /wp-content/uploads/botkibble/$1.md [L,T=text/markdown] Even without these rules, the plugin uses a “Fast-Path” that serves cached files from PHP before the main database query is executed.

Kolibia Agent-Ready makes WordPress content available as Markdown so tools and agents do not have to scrape HTML. Behaviour follows common content negotiation patterns (similar in spirit to Markdown for Agents on Cloudflare): clients that prefer Markdown can request it explicitly. What is included today Markdown responses for singular content — For each built-in public post type registered by WordPress core (post, page, attachment on a typical site), a single-item URL can return Content-Type: text/markdown; charset=UTF-8 instead of the themed HTML page. Markdown for the posts index — When the site front page shows latest posts (WordPress “Your homepage displays: Your latest posts”), the homepage and other blog-index URLs return Markdown listing the same posts as the main loop. Static or WooCommerce shop front page — When a page is set as the front page (including a WooCommerce shop page where WordPress reports is_singular as false), that page’s content is still served as Markdown on / when clients negotiate text/markdown. When Markdown is served The request includes an Accept header that lists text/markdown (requests with text/markdown;q=0 are ignored). Or the URL includes the query argument output_format=md (handy for browsers and manual testing). HTML to Markdown — Rendered post body is passed through WordPress’s the_content filters, then converted to Markdown using the league/html-to-markdown library. A short YAML front matter block includes title and permalink. Password-protected content — If a password is required, the response is a small Markdown message instead of the full body. Discovery in HTML — On the normal HTML view, the plugin prints so clients can find the Markdown URL. Admin shortcut — On the posts and pages list screens, a row action View as AI Agent opens the same Markdown URL (preview URLs are used for drafts where WordPress would show Preview). Developer filters kolibia_ar_markdown_post_types — Defaults to all public, built-in post types from core; override to add custom post types or remove types (e.g. attachment). kolibia_ar_post_markdown — Filter the final Markdown string. kolibia_ar_home_markdown — Filter the Markdown for the posts index / homepage loop. kolibia_ar_home_markdown_post_types — Post types included in the homepage Markdown list (default: post). kolibia_ar_markdown_password_required — Filter the Markdown shown when a password is required. Roadmap Further “agent readiness” features (broader API discovery, additional formats) may be added in future releases.
