A set of rules for making web pages easier for search engines and social sites to understand. It covers page titles, descriptions, link previews, crawlable text, and server-rendered content.

It helps add route metadata, Open Graph and Twitter card data, canonical information, favicons, and crawlable page structure.

It prevents missing or misleading search information and social previews, and keeps page content visible to crawlers and assistive technology.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00044	$0.00206
Opus 5.5	$0.00018	$0.00082
Sonnet 5.5	$0.00009	$0.00041
Haiku 4.5	$0.00004	$0.00021

Security

Grade A, and why

seo 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.

What it actually says

SEO

The site is findable and previews well everywhere it's shared.

Full metadata at the root: title, description, Open Graph, Twitter card, targeting the canonical domain, plus favicons and the dark theme-color.
Every route has its own title and description. Dynamic pages derive theirs from their data entry (title, intro as description, first media as the OG image).
Real text in the DOM. No content locked in images or canvas; headings and landmarks follow document order so crawlers can parse structure the same way assistive tech does.
Overlays and loading states never hide content from crawlers: page content is server-rendered and present in the initial HTML regardless of lifecycle state.

Changes

What this file has done since we first saw it

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.
