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 | $0.00191 | $0.01706 |
| Opus 5 | $0.00096 | $0.00853 |
| Sonnet 5 | $0.00038 | $0.00341 |
| Haiku 4.5 | $0.00019 | $0.00171 |
Grade A, and why
sota-ux-writing 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.

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

Other skills, from other repositories
brand
Use to establish or audit a product's brand so the factory's output looks intentional, not template — when a ticket asks to "create a brand", "define the design system / visual identity / palette / typography", or when delivered UI looks generic and needs a deliberate direction. Detects existing brand and extends it…
design-system
Use when a ticket needs a systematic token + component foundation for a frontend — the three-layer token architecture (primitive → semantic → component), component specs with full state coverage, or a recommendation for which design system a product should have. Invoke for "set up design tokens", "define the component…
frontend-design
Use when a ticket builds or reworks a user-facing frontend surface — a hero, landing page, dashboard, marketing section, or any screen where the visual quality matters, not just the markup. Produces distinctive, intentional, production-grade UI that avoids generic template aesthetics. Invoke for "build the landing…
mobile-ui
Use when a ticket builds or reworks UI in a React Native / Expo (or React + Capacitor) mobile app and it must feel like a real, store-credible native app — not a wrapped mobile website. Covers the native-feel bar, safe-area/gesture/haptics, store-readiness, and mobile performance. Invoke for "make this screen feel…
frontend-foundations
Use on any frontend delivery to hold the surface-specific quality floor that engineering-craft doesn't cover — intentional visual hierarchy over template defaults, accessible-by-default markup, design tokens instead of hardcoded values, reusable components matching the repo, and compositor-friendly motion. Invoke…
frontend-a11y
Use when a ticket requires accessibility work or when delivering UI that must be usable by everyone — keyboard navigation, screen-reader labelling, focus management, colour contrast, or reduced-motion support. Invoke for "make X accessible", "fix the a11y issues", "add keyboard support", or as a companion check on any…
