Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00003 | $0.02104 |
| Opus 5.5 | $0.00001 | $0.00842 |
| Sonnet 5.5 | $0.00001 | $0.00421 |
| Haiku 4.5 | $0.00000 | $0.00210 |
Grade A, and why
sigil-layout 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 — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sigil Layout
Compose page layouts using Sigil's page, section, rhythm, and structural-visibility primitives.
When to Use
- User asks to build a page layout, section, or screen
- User says "layout", "page structure", "grid", "compose a page"
- User wants to use sigil-grid, sigil-rail, or sigil-cross components
- User is building a landing page, dashboard, docs layout, or app shell
How to Use
1. Core page primitives
Sigil page code should describe content and structure. Token math, snap padding, gutter phase, and divider stroke placement live inside package primitives.
| Component | Purpose |
|---|---|
SigilPage |
Page shell with rhythm="locked" / rhythm="hairline" and chrome modes |
SigilHero |
Hero section root with built-in section spacing |
SigilHeroLayout / Content / Media |
Hero composition parts |
SigilSection |
Section band with named space presets |
SigilDivider |
Locked full-cell structural divider band |
Hairline |
Free-flow editorial rule |
SigilSectionHeader |
Canonical label/heading/description stack |
SigilActionRow |
Token-rhythm CTA/action row |
SigilStack |
Token-rhythm vertical stack |
SigilMonoBlock |
Token-rhythm mono/code block |
SigilGhostLink |
Secondary link CTA |
2. Page layout pattern
import {
AccentCTA,
SigilActionRow,
SigilDivider,
SigilGhostLink,
SigilHero,
SigilHeroContent,
SigilHeroLayout,
SigilHeroMedia,
SigilPage,
SigilSection,
SigilSectionHeader,
} from "@sigil-ui/components";
export function LandingPage() {
return (
<SigilPage rhythm="locked" chrome="rails">
<SigilHero>
<SigilHeroLayout>
<SigilHeroContent>
<SigilSectionHeader
label="Components"
heading="Browse the full component system."
description="Tokens and grid rhythm are handled by Sigil."
/>
<SigilActionRow>
<AccentCTA>Browse Components</AccentCTA>
<SigilGhostLink href="/docs">Read Docs</SigilGhostLink>
</SigilActionRow>
</SigilHeroContent>
<SigilHeroMedia>{/* product visual */}</SigilHeroMedia>
</SigilHeroLayout>
</SigilHero>
<SigilDivider />
</SigilPage>
);
}
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.

sigil-layout is a skill published in the GitHub repository Kevin-Liu-01/Sigil-UI (10 stars, last pushed 7d ago), licensed MIT. It adds 3 tokens to every session and 2,104 once invoked, about $0.0000 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 2026-08-31.
