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 | $0.00109 | $0.03808 |
| Opus 5 | $0.00055 | $0.01904 |
| Sonnet 5 | $0.00022 | $0.00762 |
| Haiku 4.5 | $0.00011 | $0.00381 |
Grade A, and why
aimeat-design-language 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 3d 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 — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The AIMEAT design language
One product, two faces. The showroom is what a visitor sees before signing in: the front page, how it works, for your business, help, members, the change log. The poster is what a person sees once inside: the home, every profile tab, the chat, the sign-in dialog, the app catalog. They share the type, the colours, the shapes and the rules; they differ in how loud they are. A third register, the classic shell (rounded controls, cards), remains under the admin dashboard and the oldest views and is not extended; it reads the same type tokens.
Every value in this document is a token in aimeat/public/css/theme.css. A view sheet reads the
token; it never writes a face or a colour out in full. When a value changes, it changes in that one
file, and the map at the end says which surfaces follow.
The faces
Three lines in theme.css are the whole typography; every other font token on the sheet is an
alias of one of them, so a face changes once and reaches every page, outside and in:
| Token | Value | Where |
|---|---|---|
--font-headline |
Fjalla One, uppercase, one weight | every headline, big numeral, sticker, slab and tab (the wordmark is its own token, below) |
--font-body |
Archivo | everything read as a sentence on every face: body 400, emphasis 600, actions and row names 700 to 800; also form controls and the classic shell |
--font-mono |
JetBrains Mono | identifiers, keys, crumbs, addresses, commands, small labels that name a machine thing |
The aliases a view sheet reads, and what they resolve to: --font-showroom and --font-poster are
--font-headline; --font-showroom-body, --font-poster-section and --font are --font-body.
A sheet picks the alias that names its face (showroom outside, poster inside), and never writes a
family name. A face has to be served to be used: every family is self-hosted under
aimeat/public/lib/fonts/ (woff2, latin and latin-ext, SIL OFL) and declared in
aimeat/public/lib/aimeat-fonts.css, which aimeat-theme.css imports and the standalone pages
link. Nothing on the node links a font CDN, and the CSP refuses one; a new face is vendored
there, with its row in lib/fonts/LICENSE.md, before a token names it.
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.

aimeat-design-language is a skill published in the GitHub repository miikkij/aimeat-protocol (7 stars, last pushed yesterday), licensed MIT. It adds 109 tokens to every session and 3,808 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
