Make atet.sh readable to agents without adding a hosted API

[0thernet]

Pre-deploy Is Agentic report: https://is-agentic.com/scan/atet.sh scored 74 / 100 on 2026-08-21T21:58:42.678Z (Ready with a few material gaps). Essential 60 / 80 (4 of 6). Recommended 12.2 / 20 (5 of 9). Bonus +2.1. This PR does not claim a new live score. Rescan atet.sh after production deploy.

Findings

Essential

markdown-negotiation-vary — Markdown content negotiation (acceptmarkdown.com) — failed.

Not acceptmarkdown.com compliant: Accept: text/markdown returned text/html; charset=utf-8; Vary header missing Accept (got "none")

agent-friendly-404 — Agent-friendly 404s — partial.

Nonexistent paths return a real HTTP 404. For full credit, include a short markdown body (site map links, where to look next) so agents can recover.

Recommended (fixed when the product already had the capability)

agent-instruction — Agent instruction / when-to-use — failed.

No agent instruction file with when-to-use guidance found

Recommended leftovers (need a product decision)

brand-search-accuracy — Brand name discoverability — failed.

"Atet" search returned 9 results but domain did not appear - brand may be too generic or not indexed

trust-anchors — Trust anchor pages — failed.

No trust anchor pages found with sufficient content (About, Contact, Privacy)

org-schema-completeness — Organization schema completeness — partial.

Organization schema found but missing: contactPoint, address

Changes

• Honor Accept: text/markdown on the homepage with Content-Type: text/markdown; charset=utf-8 and Vary: Accept, Accept-Encoding, including q-value parsing and 406 when the request rejects HTML and markdown.
• Publish /llms.txt (text/plain) with an H1, summary, and When to use Atet. Publish /index.md and /sitemap.md.
• Keep real HTTP 404s. HTML 404s and markdown 404s now point at /, /llms.txt, /sitemap.md, and /sitemap.xml.
• Allow the common AI fetchers explicitly in robots.txt without adding a Disallow.
• Do not add an API, OAuth, GraphQL, MCP, account, commerce, About, Contact, or Privacy surface, and do not invent an organization address or phone number.

Curl verification

After production deploy:

curl -sI -H "Accept: text/markdown" https://atet.sh/
# Content-Type: text/markdown; charset=utf-8
# Vary: Accept

curl -s -H "Accept: text/markdown" https://atet.sh/ | head
curl -sI https://atet.sh/llms.txt
# Content-Type: text/plain

curl -s https://atet.sh/llms.txt | head
curl -sI https://atet.sh/sitemap.md
curl -s -o /dev/null -w "%{http_code}\n" https://atet.sh/this-path-does-not-exist
# 404

curl -sI -H "Accept: text/markdown" https://atet.sh/this-path-does-not-exist
# 404 and Content-Type: text/markdown

curl -sI -H "Accept: application/xml" https://atet.sh/
# 406

Then npx is-agentic atet.sh for a post-deploy score.
