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. <a href="https://blog.cloudflare.com/markdown-for-agents/" rel="nofollow ugc">Cloudflare measured</a> 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 <a href="https://developers.cloudflare.com/fundamentals/reference/markdown-for-agents/" rel="nofollow ugc">Markdown for Agents</a> 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.
<a href="https://github.com/greg-randall/botkibble" rel="nofollow ugc">GitHub Repository</a>
Three ways to request Markdown:
<ul>
<li><code>.md</code> suffix: append <code>.md</code> to any post or page URL (e.g. <code>example.com/my-post.md</code>)</li>
<li>Query parameter: add <code>?format=markdown</code> to any post or page URL</li>
<li>Content negotiation: send <code>Accept: text/markdown</code> in the request header</li>
</ul>
What’s in every response:
<ul>
<li>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)</li>
<li>Clean Markdown converted from fully-rendered post HTML (shortcodes run, filters applied)</li>
<li><code>Content-Type: text/markdown</code> and <code>Vary: Accept</code> response headers</li>
<li><code>Content-Signal</code> header for AI signal declaration — defaults to <code>ai-train=no, search=yes, ai-input=yes</code> — see <a href="https://contentsignals.org/" rel="nofollow ugc">contentsignals.org</a></li>
<li><code>X-Markdown-Tokens</code> header with estimated token count</li>
<li>Discovery via <code><link rel="alternate"></code> in the HTML head and <code>Link</code> HTTP header</li>
<li>Automatic cache invalidation when a post is updated or deleted</li>
</ul>
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 <code>init</code> hook, before the main database query runs. No extra configuration needed.
Add a web server rewrite rule and Botkibble bypasses PHP entirely, serving <code>.md</code> 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:
<ul>
<li>Drafts, private posts, and password-protected content return <code>403 Forbidden</code></li>
<li>Rate limits cache-miss regenerations (20/min by default) to mitigate DoS abuse</li>
<li><code>X-Robots-Tag: noindex</code> keeps Markdown versions out of search results</li>
<li><code>Link: rel="canonical"</code> points search engines back to the HTML version</li>
</ul>
Cache variants (optional):
You can persist alternate cached representations by adding <code>?botkibble_variant=slim</code> (or any other variant name). 
Variant caches are stored under:
<pre><code>/wp-content/uploads/botkibble/_v/<variant>/<slug>.md
</code></pre>
What it does NOT do:
<ul>
<li>Expose drafts, private posts, or password-protected content</li>
<li>Serve non-post/page content types by default</li>
<li>Require any configuration. Activate and it works.</li>
</ul>
<h3>Why Markdown?</h3>
HTML is expensive for AI systems to process. <a href="https://blog.cloudflare.com/markdown-for-agents/" rel="nofollow ugc">Cloudflare measured</a> 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 <a href="https://developers.cloudflare.com/fundamentals/reference/markdown-for-agents/" rel="nofollow ugc">Markdown for Agents</a> at the CDN edge via the <code>Accept: text/markdown</code> 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 <code>.md</code> suffix URLs, <code>?format=markdown</code> query parameters, YAML frontmatter, static file caching, and server-level offloading.
If you use Cloudflare, both share the same <code>Accept: text/markdown</code> header, <code>Content-Signal</code> headers, and <code>X-Markdown-Tokens</code> response headers.
Cloudflare currently defaults to <code>Content-Signal: ai-train=yes, search=yes, ai-input=yes</code> with no way to change it. Botkibble defaults to <code>ai-train=no</code> and lets you override the full signal per site via the <code>botkibble_content_signal</code> filter.
<h3>Performance & Static Offloading</h3>
This plugin supports static file offloading by writing Markdown content to <code>/wp-content/uploads/botkibble/</code>.
<h3>Nginx Configuration</h3>
To bypass PHP entirely and have Nginx serve the files (including variants) directly:
<pre><code># 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;
}
</code></pre>
<h3>Apache (.htaccess)</h3>
Add this to your <code>.htaccess</code> before the WordPress rules:
<pre><code>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]
</code></pre>
Even without these rules, the plugin uses a “Fast-Path” that serves cached files from PHP before the main database query is executed.
