Markdown Content Negotiator for LLMs

A WordPress plugin that detects when a request is made for content in Markdown format (via the Accept: text/markdown header) and serves a clean, pre-generated Markdown version of the page instead of HTML.

🚀 Features

• Content Negotiation: Detects Accept: text/markdown and bypasses the standard theme template.
• YAML Frontmatter: Automatically prepends metadata (Title, Date, Author, Categories, Permalink).
• Automated Caching: Uses WP-Cron to pre-generate Markdown for all published posts and pages to minimize response time.
• LLM-Friendly Headers:
  • X-Markdown-Tokens: Estimates token count using standard heuristics.
  • X-Content-Signal: Provides document metadata (type, depth, priority) and custom signals.
• Customizable: Admin settings page to select Post Types and configure global content signals.

📥 Installation

1. Clone or download this repository.
2. Upload the folder to your wp-content/plugins/ directory.
3. Activate the plugin in the WordPress Admin.
4. Go to Settings > AI Markdown to configure your settings.

🛠 Usage

To request the Markdown version of a post, include the appropriate header in your HTTP request:

curl -H "Accept: text/markdown" https://yourdomain.com/your-post/
