UpAssist.Neos.Llms
==================

[](#upassistneosllms)

Serves `/llms.txt` from your Neos CMS site so AI agents can discover and navigate the site's content.

[`llms.txt`](https://llmstxt.org) is a plain-text index of a site's documents, analogous to `robots.txt` but aimed at LLMs. This package turns the Neos content tree into one, honours `noindex` / hidden flags, and lets editors opt pages out per-node.

Features
--------

[](#features)

- Renders `/llms.txt` directly from the content tree — no static file to maintain.
- Auto-excludes nodes with `metaRobotsNoindex`, `_hidden`, or the package's `llmsTxtHidden` flag.
- Per-site description (editable on the Home node).
- 1h output cache, invalidated by content changes.

Installation
------------

[](#installation)

Works on **both Neos 8 and Neos 9** — pick the constraint that matches your Neos version:

Neos versionComposer constraintBranchNeos 8.x`^1.0` or `dev-neos-8``neos-8`Neos 9.x`^2.0` or `dev-main``main`This branch targets **Neos 9**. Only difference from the Neos 8 branch: the route part handler interface namespace is `Neos\Neos\FrontendRouting\` (Neos 8 uses `Neos\Neos\Routing\`). Everything else — mixin, Fusion helper, caching, translations, per-page `llmsTxtDescription` with `metaDescription` fallback — is shared 1:1.

```
composer require upassist/neos-llms:^2.0
```

Or add a repository to your `composer.json`:

```
{
    "repositories": [
        {
            "type": "git",
            "url": "git@github.com:UpAssist/neos-llms.git"
        }
    ],
    "require": {
        "upassist/neos-llms": "^2.0"
    }
}
```

Usage
-----

[](#usage)

### 1. Attach the mixin to your Document NodeTypes

[](#1-attach-the-mixin-to-your-document-nodetypes)

Apply the mixin to the Document NodeTypes you want to include in `llms.txt`. The mixin adds:

- `llmsTxtHidden: boolean` — per-page opt-out checkbox under the *AI / LLMs* inspector group.
- `llmsTxtDescription: string` (TextArea) — only relevant on your site/home node; used as the blockquote under the site title.

```
'Your.Package:Document.Page':
  superTypes:
    'UpAssist.Neos.Llms:Mixin.LlmsTxt': true

'Your.Package:Document.Home':
  superTypes:
    'UpAssist.Neos.Llms:Mixin.LlmsTxt': true
```

### 2. Register the route

[](#2-register-the-route)

The package ships a `Routes.yaml`. Register it in your site package's `Configuration/Settings.yaml` so the `/llms.txt` URL is routed:

```
Neos:
  Flow:
    mvc:
      routes:
        'UpAssist.Neos.Llms':
          position: 'before Neos.Neos'
```

### 3. Fill the descriptions

[](#3-fill-the-descriptions)

In the Neos backend, every document with the mixin exposes an *AI / LLMs* inspector group with a `llmsTxtDescription` textarea:

- **On the site/home node**, it becomes the `> blockquote` under the site title.
- **On other pages**, it becomes the per-page entry after the page title. If empty, the page entry falls back to `metaDescription`.

Prefer filling `llmsTxtDescription` per page when you want an AI-facing summary that differs from the SEO meta description (e.g. more factual, less marketing).

Exclusion rules
---------------

[](#exclusion-rules)

A document does **not** appear in `llms.txt` when any of the following is true:

- `llmsTxtHidden: true` (per-page opt-out)
- `_hidden: true` (Neos "hidden" flag)
- `metaRobotsNoindex: true` (Neos.Seo noindex)

This means setting a page to `noindex` for search engines also removes it from `llms.txt` — no double bookkeeping.

Output
------

[](#output)

```
# {Site Title}

> {llmsTxtDescription}

## Pages

- [Page Title](https://example.com/page): metaDescription truncated to 200 chars
- ...

```

Served with `Content-Type: text/plain; charset=utf-8`. Cached for 1 hour, tagged `Everything` so regular content publishes invalidate it.

Customising the "Pages" heading
-------------------------------

[](#customising-the-pages-heading)

Override the Fusion prototype to change the heading label:

```
prototype(UpAssist.Neos.Llms:Helper.LlmsTxt) {
    pagesHeading = 'Documents'
}

```
