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 | $0.00039 | $0.01624 |
| Opus 5 | $0.00019 | $0.00812 |
| Sonnet 5 | $0.00008 | $0.00325 |
| Haiku 4.5 | $0.00004 | $0.00162 |
Grade A, and why
frontend-ui-dark-ts 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 8d 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.

Frontend UI Dark (TypeScript)
Critical rules (non-obvious)
- WCAG contrast minimums: text on bg requires 4.5:1 (AA) or 7:1 (AAA); UI elements (borders, icons) require 3:1
- Never use
prefers-color-schememedia query alone — users need a toggle; sync withlocalStorageto avoid flash on hydration - HSL for dark themes: use
hsl(220 15% 10%)not#1a1a2e— HSL lets you programmatically adjust lightness - Avoid pure black (
#000) for dark backgrounds — causes eye strain; usehsl(220 15% 8%)instead color-scheme: darkon:rootmakes browser UI (scrollbars, inputs) follow dark theme

Theme provider (React + no flash)
// providers/ThemeProvider.tsx
export function ThemeProvider({ children }: { children: React.ReactNode }) {
const [theme, setTheme] = useState<"dark" | "light">(() =>
typeof window !== "undefined"
? (localStorage.getItem("theme") as "dark" | "light") ?? "dark"
: "dark"
);
useEffect(() => {
document.documentElement.dataset.theme = theme;
localStorage.setItem("theme", theme);
}, [theme]);
return (
<ThemeContext.Provider value={{ theme, toggle: () => setTheme(t => t === "dark" ? "light" : "dark") }}>
{children}
</ThemeContext.Provider>
);
}
// Prevent flash — add to <head> before React hydrates
const themeScript = `
(function() {
var t = localStorage.getItem('theme') || 'dark';
document.documentElement.dataset.theme = t;
})();

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.

frontend-ui-dark-ts is a skill published in the GitHub repository tranhieutt/software_development_department (72 stars, last pushed 4mo ago), licensed MIT.
