What is it for?
Use it to add static or dynamic URLs to a sitemap and point robots.txt to that sitemap.
Why use it?
It helps search engines find indexable pages through standard endpoints and requires no extra dependency. It is not intended for private applications with no public pages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sitemap scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

XML Sitemaps

Serves an XML sitemap at /sitemap.xml using a plain Phoenix controller and an EEx template, and wires robots.txt to point at it. No external dependencies — it adds the :xml format to the web entrypoint, a route, a SitemapController, a SitemapXML view, and the template you edit to list your URLs.

When to use

  • The app is public and you want search engines to discover its pages.
  • You need a standards-compliant (sitemaps.org) sitemap served with the correct XML content type.
  • Don't bother for an internal/admin-only app with no indexable public pages.

Dependencies

  • Requires: None.
  • Recommended: None.

Install

mix saaskit.feature.install sitemap

No installer decisions. It injects the :xml format and route, appends the Sitemap: line to robots.txt, and generates the controller, view, template, and test.

What it generates

  • lib/my_app_web/controllers/sitemap_controller.ex — index/2 renders index.xml with layout: false and text/xml content type.
  • lib/my_app_web/controllers/sitemap_xml.ex — SitemapXML view using embed_templates "sitemap_xml/*".
  • lib/my_app_web/controllers/sitemap_xml/index.xml.eex — the sitemap template (one <url> entry for / by default).
  • test/my_app_web/controllers/sitemap_controller_test.exs — asserts the route returns XML.
  • Adds :xml to the allowed formats in lib/my_app_web.ex.
  • Adds get "/sitemap.xml", SitemapController, :index to lib/my_app_web/router.ex.
  • Appends Sitemap: https://example.com/sitemap.xml to priv/static/robots.txt.

Configuration

No config keys. The only value to change is the domain in priv/static/robots.txt:

Sitemap: https://example.com/sitemap.xml

Replace example.com with your production domain.

Tweaking for your app

Add static routes to the template:

<%# lib/my_app_web/controllers/sitemap_xml/index.xml.eex %>
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="https://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc><%= url(~p"/") %></loc>
    <changefreq>daily</changefreq>

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
