How do I wire the generators into an Astro build?

[RelayStack]

I want llms.txt, sitemap.xml and robots.txt regenerated on every build so they never go stale. What is the recommended setup — copy the scripts into my project or use npx?

Both work. Recommended: keep the generators out of your source tree and pin them through npx in your build hook, so public/ is always fresh:

{ "scripts": {
  "seo": "npx -y github:RelayStack/astro-seo-toolkit astro-seo-llms --dir src/content --site https://example.com --out public/llms.txt && npx -y github:RelayStack/astro-seo-toolkit astro-seo-sitemap --dir src/content --site https://example.com --out public/sitemap.xml",
  "build": "npm run seo && astro build"
} }

Three details that matter:

1. Point --dir at the content collection (src/content/...), not src/pages — otherwise drafts and components leak into the sitemap.
2. Titles/descriptions come from frontmatter. Pages without frontmatter fall back to slug + stripped excerpt, so treat a fallback in the output as a missing-frontmatter bug.
3. Verify after build with node check.mjs --dir public --site https://example.com (or the audit command of the astro-seo skill) — it fails on sitemap/llms.txt drift before you deploy it.

Alternative: vendor the five .mjs files into ./seo/ if you need to work offline or pin an exact version. The examples/astro/ folder in this repo shows the full pattern.
