## Description

Markdown Content Negotiator for LLMs is a performance-optimized WordPress plugin
designed to serve your website’s content in a format that AI agents and LLMs (Large
Language Models) love: Clean Markdown.

Using standard HTTP Content Negotiation, the plugin detects when a request is made
with the `Accept: text/markdown` header. Instead of serving the standard HTML theme,
it returns a Markdown version of the post or page, complete with YAML Frontmatter,
token estimation headers, and customizable content signals.

To ensure maximum performance and minimal server load, Markdown versions are pre-
generated and cached using WP-Cron.

#### Key Features

 * **Content Negotiation**: Automatically switches to Markdown output when requested
   via the `Accept: text/markdown` header.
 * **YAML Frontmatter**: Includes metadata like Title, Date, Author, and Categories
   in a structured format.
 * **Performance Tracking**: Provides an `X-Markdown-Tokens` header using standard
   LLM token heuristics.
 * **AI Metadata**: Includes `X-Content-Signal` headers to help agents understand
   the nature of the document.
 * **Background Caching**: Uses WP-Cron to pre-calculate Markdown strings, ensuring
   zero latency during requests.
 * **Admin Settings**: Choose which post types to enable and configure global AI
   content signals.

## Installation

 1. Upload the `markdown-content-negotiator-for-llms` folder to the `/wp-content/plugins/`
    directory.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Configure your preferences under ‘Settings > AI Markdown’.

## FAQ

### How do I test the Markdown output?

You can test it using a tool like cURL:

    ```
    curl -H "Accept: text/markdown" https://your-site.com/post-slug/
    ```

### How are tokens calculated?

We use a standard heuristic of ~4 characters per token to provide an estimate in
the `X-Markdown-Tokens` header.
