Generate or update the site's /llms.txt endpoint. Run this after adding, removing, or significantly editing content.

Overview

The /llms.txt file follows the llmstxt.org specification — a Markdown file at the site root that helps LLMs understand the site's content and structure.

Step 1 — Read site context

Read these files to understand the current site state:

•src/config.ts — author info, site URL, social links, navigation
•src/pages.config.ts — page descriptions and headings
•src/content.config.ts — content collection schemas

Step 2 — Read all content collections

Read all non-draft MDX files from each collection to gather titles, summaries, and metadata:

•src/content/projects/*.mdx — extract title, role, year, outcomeSummary, status
•src/content/publications/*.mdx — extract title, authors, journal, publishDate
•src/content/journey/*.mdx — extract date, title, type, description
•src/content/tools/*.mdx — extract name, description, is_favorite

Filter out any entries with draft: true.

Step 3 — Generate llms.txt content

Follow the llmstxt.org specification exactly:

markdown

# {Site Title}

> {Brief summary of the site and its author — 2-3 sentences from config and pages.config}

{A short paragraph about the site's purpose, structure, and content types}

## Projects

- [{title}]({url}): {outcomeSummary}
  (repeat for each non-draft project, sorted by year descending)

## Publications

- [{title}]({url}): {journal}, {publishDate year}. Authors: {authors joined}
  (repeat for each non-draft publication, sorted by publishDate descending)

## Journey

- [{title}]({url}): {description} ({date year})
  (repeat for each non-draft journey entry, sorted by date descending)

## Tools

- [{name}]({url}): {description}
  (repeat for each non-draft tool, sorted by is_favorite descending then name)

## Optional

- [Sitemap]({siteUrl}/sitemap-index.xml): XML sitemap for all pages

URL format

•Projects: {siteUrl}/projects/{slug}/
•Publications: {siteUrl}/publications/ (publications are listed on a single paginated page, no individual routes)
•Journey: {siteUrl}/journey/ (journey is a single timeline page, no individual routes)
•Tools: {siteUrl}/tools/ (tools are listed on a single page, no individual routes)

For collections without individual pages (publications, journey, tools), link to the listing page instead of per-item URLs.

Slug derivation

Project slugs are derived from the MDX filename (without .mdx extension).

Step 4 — Write the endpoint

The file should be an Astro API route at src/pages/llms.txt.ts, following the same pattern as src/pages/robots.txt.ts:

•Import content collections using getCollection from astro:content
•Filter out drafts
•Sort entries as specified above
•Build the Markdown string
•Return a Response with Content-Type: text/plain; charset=utf-8

If the file already exists, update it. If not, create it.

Step 5 — Validate

•Run bun run build to verify the route compiles
•Check that dist/llms.txt exists in the build output and contains the expected content
