Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

copilot-instructions ui-ux.instructions.md 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.

Design System

Typography

  • Base typography 14–16px
  • Line-height 1.4–1.6
  • Use clamp() for fluid sizing
  • Avoid very thin fonts
  • Font pairing: Display font (Poppins) for titles, Body font (Inter) for text
:root {
  --theme-font-display: 'Poppins', sans-serif;
  --theme-font-body: 'Inter', sans-serif;
}

h1, h2, h3 {
  font-family: var(--theme-font-display);
  font-weight: 700;
}

body {
  font-family: var(--theme-font-body);
  font-size: clamp(14px, 1.5vw, 16px);
  line-height: 1.5;
}

Spacing Scale

  • Base spacing 8px (4px for dense)
  • Consistent tokens in design-system.scss
:root {
  --spacing-xs: 4px;
  --spacing-sm: 8px;
  --spacing-md: 16px;
  --spacing-lg: 24px;
  --spacing-xl: 32px;
  --spacing-2xl: 48px;
  --spacing-3xl: 64px;
  --spacing-4xl: 80px;
}

Shadows (Softer for Modern Look)

:root {
  --shadow-soft: 0 2px 8px rgba(0, 0, 0, 0.05);
  --shadow-medium: 0 4px 16px rgba(0, 0, 0, 0.08);
  --shadow-strong: 0 8px 32px rgba(0, 0, 0, 0.1);
}

.card {
  box-shadow: var(--shadow-soft);
  transition: box-shadow var(--transition-fast);
}

.card:hover {
  box-shadow: var(--shadow-medium);
}

Transitions

:root {
  --transition-fast: 200ms ease-in-out;
  --transition-normal: 300ms ease-in-out;
  --transition-slow: 500ms ease-in-out;
}

CSS Variables

  • Theme variables for runtime switching: --theme-*
  • Static tokens for design system: --spacing-*, --shadow-*, --transition-*
  • Quasar utility classes first - prefer built-in classes over custom CSS
/* design-system.scss - Theme Variables */
:root {
  /* Theme colors (switchable at runtime) */

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.
