Manage your site's llms.txt file — the AI equivalent of robots.txt — straight from the WordPress dashboard.

== Description ==

**5Names LLMs.txt Manager** lets you manage the `llms.txt` file for your WordPress site directly from the dashboard. A product by [5Names](https://5names.nl).

`llms.txt` is a proposed standard (see [llmstxt.org](https://llmstxt.org)) for a Markdown file in your site's root that gives AI language models (like ChatGPT, Claude, or Perplexity) a concise, structured overview of your site: who you are, which pages matter, and where to find more information — similar to what `robots.txt` does for search engine crawlers, but written for and readable by an LLM.

= How does it work? =

The plugin generates `/llms.txt` from two sources, each of which you can toggle independently:

1. **Automatically from your WordPress content** — choose which parts are included automatically: your site tagline as an intro quote, published pages, categories with their recent posts, and any custom post type your site uses.
2. **Manual sections** — your own `## Section` blocks with links and short descriptions, for anything that can't be generated automatically.

On save, the plugin combines both sources into a single Markdown file and writes it via `WP_Filesystem` (with a `file_put_contents` fallback) to `llms.txt` in your site's root. A **live preview** always shows you the result before you save.

= Importing an existing llms.txt =

Already have an `llms.txt` file (e.g. created by hand)? On activation you'll get a notice, and **Import existing file** reads the file and automatically converts it into sections, links, and a description (including multi-line blockquotes) — so nothing gets lost and you can carry on with the visual editor right away.

= Source editor =

Prefer to edit the Markdown directly? The **Source** tab lets you edit the text directly and save it without touching the visual settings. Note: saving from visual mode overwrites manual source edits with the generated content again.

= Automatic backups =

Every save writes the previous version of `llms.txt` to a protected folder (`wp-content/llms-backups/`, with an `.htaccess` file that blocks direct access). The last 10 versions are kept; older ones are removed automatically. **Version history** lets you restore an earlier version with one click.

= Sitemap detection =

Enable the "Sitemap" option and the plugin adds an `## Optional` section with a link to your sitemap. It automatically detects whether Yoast SEO or RankMath is active (and uses `/sitemap_index.xml` in that case), otherwise it falls back to the built-in WordPress sitemap (`/wp-sitemap.xml`).

= Webhook after saving =

Optional: provide a URL that receives a GET request after every successful save. Handy for clearing a CDN cache (like a Cloudflare Purge URL) whenever `llms.txt` changes.

== Installation ==

1. Upload the `5names-llms-txt-manager` folder to `/wp-content/plugins/`.
2. Activate the plugin through the **Plugins** menu in WordPress.
3. If a `/llms.txt` file already exists: click **Import existing file**.
4. Go to **Settings → LLMs.txt** to configure the file.

== Frequently Asked Questions ==

= What exactly is llms.txt? =

A proposed standard for a Markdown file at `/llms.txt` that gives AI language models a concise overview of your site. See llmstxt.org for the full specification.

= Do I need write access to the site root? =

Yes, the plugin needs to be able to write to `ABSPATH` (the WordPress root folder). If it can't, the plugin shows a clear notice with the action to take (`chmod 755` on the folder).

= What happens to my llms.txt if I delete the plugin? =

The file itself stays in place — the plugin doesn't delete it on uninstall. Only the saved settings (`fivenames_llmtxt_settings`) and any activation notice are cleaned up. Backups stored in `wp-content/llms-backups/` are also left in place.

= Does this work with custom post types? =

Yes. Every public, non-built-in custom post type on your site appears as a separate checkbox under "Auto-generate", with its posts included as a section in the file.

= Does this plugin send any data to external services? =

No. Everything runs locally on your own server. The only outbound request the plugin makes is the optional webhook you configure yourself (e.g. to purge a CDN cache) — nothing is sent anywhere unless you explicitly set that up.

= Does this work with multisite? =

The plugin activates per-site like any standard plugin; each site in a multisite network manages its own `llms.txt` file and settings independently.
