Notes for Reviewers

Description

Currently, the Layer5 documentation does not generate llms.txt files for AI agents.
This PR aims to enable LLM-friendly content generation by integrating the Hugo Module for llms.txt and llms-full.txt
In addition, this PR adds a View as Markdown link to every page. The link directs users to the generated llms.txt representation of the current page, providing an LLM-friendly Markdown version of the content.

This PR fixes #1205

Explanation

Issue #1205 requires documented Hugo and Docsy investigation with supporting references. CONTRIBUTING.md only states that Hugo generates Markdown and provides no Hugo or Docsy links or findings. The implementation adds "md" to [outputs], but the reviewed changes define no [outputFormats.md], Markdown output template, or equivalent content transformation. page-markdown.html only links when .OutputFormats.Get "md" returns a format. The diff therefore does not establish that every page produces clean Markdown with preserved headings, code blocks, tables, and links.

Resolution

Document the Hugo and Docsy investigation with supporting links. Define and validate a supported Markdown or plain-text output for content pages, including its template/content transformation and generated URL. Add coverage that verifies the visible link and that the generated output excludes site chrome while preserving the required content.

Still using {{ .Plain }} here — unchanged from CodeRabbit's original comment. This thread shows as resolved because the visible "View as Markdown" link got repointed to the md output format in a later commit (a good fix), not because this line changed.

.Plain strips all Markdown structure — headings, code fences, and link syntax are all lost in the direct llms.txt output.

If that's intentional (llms.txt as a concise, unstructured summary vs. llms-full.txt as the structured version), that's a reasonable design — just worth a maintainer confirming intent here rather than leaving it looking like a missed fix.

Summary

Reviewed the code directly, including the imported gethugothemes/hugo-modules/llms-txt module source, not just this diff.

What's solid

  • The View as Markdown link (page-llms-link.html) targets .OutputFormats.Get "md", which resolves via the imported module's config.toml and renders through its single.md/list.md templates using .RawContent — so the actual per-page output correctly preserves headings, code fences, and links, satisfying #1205's acceptance criteria.
  • Output formats are wired into home, page, section, taxonomy, and term — broader page-kind coverage than a hand-rolled version would likely have.
  • CONTRIBUTING.md documents the feature with links to the upstream module and the Hugo Discourse thread — satisfies the issue's sourcing/documentation requirement.
  • Generates a spec-aligned site-wide llms.txt / llms-full.txt, grouped by section, via the module's own templates.
  • Checks are green: DCO signed, preview build succeeds, no conflicts with base.

One open item

layouts/_default/single.llms.txt and list.llms.txt still use .Plain — see inline comments. CodeRabbit flagged this exact line; it shows "Resolved," but the code is unchanged. The link itself got redirected elsewhere, which is a good fix for the primary feature, but the direct /page/llms.txt output is still structure-stripped. Worth confirming whether that's intentional.

Minor nit

hugo.toml redefines [outputFormats.llms] / [outputFormats.llmsfull] with values identical to what the imported module's config.toml already provides — redundant, not harmful.

Ty! Aside from my specific feedback regarding the CONTRIBUTING.MD, please address the following points:

1. llms and llmsfull should only be enabled for home

Those two formats produce a single site-wide /llms.txt and /llms-full.txt, and the module only ships templates for them at the home page (layouts/index.llms, layouts/index.llmsfull). Its README enables them for home alone, with md for the other page kinds.

Enabling them for page, section, taxonomy and term, plus the four new templates, writes a llms.txt and a llms-full.txt next to every page's index.md, all three with substantially the same content. With 1,462 content files that is roughly 2,900 extra published files, and nothing links to or requests them.

[outputs]
home     = ["HTML", "RSS", "SITEMAP", "llms", "llmsfull", "md"]
page     = ["HTML", "md"]
section  = ["HTML", "RSS", "md"]
taxonomy = ["HTML", "RSS", "md"]
term     = ["HTML", "RSS", "md"]

2. Remove the four new templates

With the config above, layouts/_default/single.llms.txt, list.llms.txt, single.llmsfull.txt and list.llmsfull.txt are unused, and the module's _default/single.md and _default/list.md already render the per-page markdown.

Also, in the llmsfull templates: {{ with .RawContent }}{{ . }}{{ else }}{{ .RawContent }}{{ end }} — the else branch re-evaluates the same value the condition just found empty, so it has no effect.

3. Remove the change to layouts/video/video.html

That template is standalone (its own <!DOCTYPE html>, it does not use video/baseof.html) and is selected only by content/en/videos/_index.md via layout: "video". Every other page under /videos/ renders through video/baseof.html, which already calls page-meta-links.html, so they pick up the link from your change to that partial.

On that one page specifically: video.html never renders .Content, .RawContent or .Summary, so the ~2,600 characters of body text in _index.md are currently unpublished, and the md output would publish them. The placement is also inconsistent with the rest of the site, sitting inside the hero between the <h1> and the subtitle rather than in the td-page-meta block.

4. CONTRIBUTING.md

It says the link targets the page's llms.txt output. It targets the md output format. Worth fixing since this section exists to keep future template authors from breaking it.

The issue also asks (acceptance test 1) that the PR or issue document whether Hugo core or Docsy already provide this capability. Hugo 0.158 has a built-in markdown output format, so a short note on why the module was used instead would close that item.

5. Shortcodes in the markdown output

The module's single.md uses .RawContent, so shortcodes are written out unexpanded, e.g. {{< alert >}}...{{< /alert >}}. 132 files under content/ use shortcodes, and the acceptance criteria ask for output that preserves headings, code blocks, tables and links. .RenderShortcodes expands them, but that means overriding a module template locally, so I would leave the decision to the maintainers.

Thank you, @banana-three-join, for the review.
You’re right. Previously, I was generating an llms.txt file for every page in the docs because I thought this would make the repository more AI-friendly. However, after further research, I found that AI systems could treat these files similarly to the existing index.md/Markdown representation, which is already available for every page through “View as Markdown.” In that case, adding a per-page llms.txt would largely duplicate the existing content.
By removing the per-page llms.txt files, there is also no longer a need to add a dedicated layout for them.
Thank you again for the review.

The output-format config and the removal of the redundant .llms.txt templates look right. Three things left.

Shortcodes are not expanded in the Markdown output

The md output renders through the module's _default/single.md / list.md, which use .RawContent, so shortcodes pass through unexpanded. 131 of the 1,447 files under content/en/ contain shortcodes (86 use alert), and any link written with ref loses its destination — in kanvas/operator/resource-details:

See [Interactive Terminal]({{< ref "kanvas/operator/interactive-terminal/index.md" >}}).

That fails the "preserves ... links" criterion in #1205. .RenderShortcodes resolves it to the real URL. Override the module templates:

{{/* layouts/_default/single.md */}}
# {{ .Title }}
{{ with .Date }}
date: {{ .Format "2006-01-02" }}
{{- end }}
{{ with .Params.description }}
> {{ . }}
{{- end }}

{{ if .RawContent }}{{ .RenderShortcodes }}{{ else }}{{ .Summary | plainify }}{{ end }}

Same substitution in layouts/_default/list.md. This will pass through the HTML emitted by card, cardpane, and alert. Please also bump [module.hugoVersion] min from 0.112.0 — the llms-txt module requires 0.147.2.

Revert on my previous suggestion of removing the link from /videos/

#1205 asks for a link on every content page so my previous suggestion is technically invalid. layouts/video/baseof.html already calls page-meta-links.html, so video pages are covered — except content/en/videos/_index.md, which sets layout: "video" and renders through layouts/video/video.html, a standalone document that bypasses baseof.

The earlier placement sat outside any .td-page-meta wrapper, so it took default anchor styling instead of the $gray-400 / white-on-hover rule in _styles_project.scss. Restore it wrapped:

  <div class="hero-section-wrapper">
    <h1>{{ .Title }}</h1>
    <p class="hero-subtitle">{{ .Description }}</p>
    <div class="td-page-meta">
      {{ partial "page-markdown-link.html" . }}
    </div>

Also. The home page (home.html_default/baseof.html) is the other page still uncovered.

CONTRIBUTING.md section

Three inaccuracies: the output comes from the llms-txt module's md output format, not Hugo's built-in Markdown rendering; it is raw source via .RawContent, not rendered content; and "every rendered documentation page" is not true while the home page and /videos/ have no link. It also omits /llms.txt and /llms-full.txt, which this PR now generates.

The # heading directly above ## Prerequisites also reparents Prerequisites, which belongs to General Contribution Flow, and the Sections list at the top of the file was not updated. Move the section below "Documentation Contribution Flow" at ## and replace the text with:

## <a name="markdown-export">LLM-friendly page output</a>

Every documentation page is also published as Markdown. The **View as Markdown**
link in the page's right-hand meta column points to `<page-url>/index.md`, which
carries the page title, description, and body content with no navigation,
sidebar, footer, or styling. Hugo also generates [`/llms.txt`](https://llmstxt.org/)
and `/llms-full.txt` at the site root for AI agents that index the whole site.

This comes from the [llms-txt Hugo module](https://github.com/gethugothemes/hugo-modules/tree/master/llms-txt),
imported in `hugo.toml`, which registers the `llms`, `llmsfull`, and `md` output
formats. Neither Hugo core nor Docsy v0.14.3 ships this capability; see the
[module announcement](https://discourse.gohugo.io/t/hugo-module-for-llms-txt-and-llms-full-txt/56990).

If you add a new page layout, include `{{ partial "page-markdown-link.html" . }}`
in it, or reuse `page-meta-links.html`, so the new pages keep the link. To leave
a path out of `llms.txt`, add it to `exclude` under `[params.llms]` in `hugo.toml`.
