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

design-tokens 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 7d 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 it actually says

Design-token strict (binding, theme/mode safety)

You are editing UI code. All visual values (color, background, border, shadow, padding / margin / gap, font-size, font-weight, border-radius, transition, z-index) must be referenced through CSS variables.

Token layers

  • Layer 1 raw tokens--g-gray-*, --g-space-*, --g-radius-*, --g-shadow-*, --g-transition-*, --g-z-*. Defined in packages/ui-shared/src/styles/global.css.
  • Layer 2 semantic tokens--color-*, --sidebar-*, --shadow-*, --space-*, --font-size-*, --radius-*, --transition-*, --z-*. Defined in light.css / dark.css and flip with data-theme.

Components consume Layer 2 by default (semantic intent). Drop to Layer 1 only when semantically neutral.

Forbidden

  • Hex / rgb(a) / hsl(a) literals in *.module.css.
  • Hex / rgb(a) literals inside style={{}} blocks.
  • Raw numeric padding: 8 / fontSize: 14 / borderRadius: 4 etc. in style={{}}.

Three escape hatches

  1. Recharts colours — must import from packages/ui-shared/src/theme/chartColors.ts (the single sanctioned hex source).
  2. CSS variable bridgesstyle={{ '--foo': dynamicValue }} is fine.
  3. Runtime-computed dimensionsstyle={{ paddingLeft: `${level * 20}px` }} is fine.

Anything else needs an explicit user waiver in chat.

Enforcement

npm run check:design-tokens           # CI gate
npm run check:design-tokens:hints     # migration suggestions when refactoring legacy code

Skipping this rule requires explicit user approval in chat.

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.
