Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00073 | $0.00807 |
| Opus 5.5 | $0.00029 | $0.00323 |
| Sonnet 5.5 | $0.00015 | $0.00161 |
| Haiku 4.5 | $0.00007 | $0.00081 |
Grade A, and why
sites-canvas-design 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 12d 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.

Sites Canvas Design — HTML5 Canvas e SVG
Quando usar Canvas vs SVG
| Canvas | SVG |
|---|---|
| Gráficos dinâmicos (dados em tempo real) | Ícones e ilustrações estáticas |
| Efeitos de partículas | Animações CSS/SMIL |
| Jogos e simulações | Logos e elementos de marca |
| Processamento de imagem | Diagramas e infográficos |
SVG otimizado para web
export function Icon({ className }: { className?: string }) {
return (
<svg
xmlns="http://www.w3.org/2000/svg"
viewBox="0 0 24 24"
fill="none"
stroke="currentColor"
strokeWidth={2}
className={cn("h-6 w-6", className)}
aria-hidden="true"
>
<path ... />
</svg>
)
}
Backgrounds CSS avançados
Fundo deriva da paleta da marca; gradiente só se a marca pedir. Mesh gradient azul/violeta/rosa e
grid de linhas finas cinza atrás do hero são o sinal nº 1 de "cara de IA" — não são padrão aqui. Antes
de qualquer fundo decorativo, pergunte o que ele diz sobre o assunto da página; se a resposta for
"nada", use cor sólida do token (--color-background, --color-muted) e deixe o conteúdo trabalhar.
/* Fundo tonal da marca — duas paradas da PRÓPRIA paleta, contraste baixo.
Só use se o sistema visual do projeto previr gradiente. */
.bg-marca {
background: linear-gradient(180deg, var(--color-background) 0%, var(--color-muted) 100%);
}
/* Padrão geométrico só quando ele vem da identidade (ex.: grade de planta para arquitetura,
pauta para educação) — traço e cor saem dos tokens, nunca cinza genérico fixo */
.bg-padrao-marca {
background-image: linear-gradient(to right, var(--color-border) 1px, transparent 1px);
background-size: var(--padrao-passo, 48px) 100%;
}
/* Noise texture */
.bg-noise::after {
content: '';
position: absolute;
inset: 0;
background-image: url("data:image/svg+xml,...");
opacity: 0.04;
}
Canvas — animação de partículas simples
useEffect(() => {
const canvas = canvasRef.current
if (!canvas) return
const ctx = canvas.getContext('2d')
if (!ctx) return
let rafId: number
const animate = () => {
ctx.clearRect(0, 0, canvas.width, canvas.height)
particles.forEach(p => { p.update(); p.draw(ctx) })
rafId = requestAnimationFrame(animate)
}
rafId = requestAnimationFrame(animate)
return () => cancelAnimationFrame(rafId)
}, [])
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.

sites-canvas-design is a skill published in the GitHub repository joaoguirunas/team-os (6 stars, last pushed today), licensed MIT. It adds 73 tokens to every session and 807 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-03.
