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

mobile-frontend 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 9d 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.

mobile-frontend

Композитный скилл для качественной мобильной вёрстки и фронтенда: от правил (отступы, шрифты, якоря, токены) через сборку к многоуровневой проверке с отладкой каждого элемента — включая меню и навигацию — и финальному аудиту перед сдачей. Это «дирижёр»: он держит единый воркфлоу и перенаправляет узкие задачи соседним скиллам (frontend-design-taste, frontend-perfection, /visual-qa, /frontend), а сам владеет мобильными правилами и чек-листом отладки навигации.

Когда использовать

  • «сделай мобильную версию», «mobile-first вёрстка», «адаптив под телефон»
  • «проверь мобилку», «аудит мобильной вёрстки», «mobile QA»
  • «меню/гамбургер не работает на телефоне», «якоря упираются в шапку»
  • «доведи мобильный фронт до идеала», «mobile lighthouse 100»

Не подменяйте этим скиллом

  • Чистая эстетика/палитра без мобильного контекста → frontend-design-taste
  • Глубокий a11y-аудит (ARIA, контраст, фокус-ловушки, скринридер) → frontend-a11y
  • Глубокий perf-аудит (заголовки, вес бандла, CWV, resource-hints) → frontend-performance
  • E2E/визуальные/контрактные тесты → frontend-testing
  • Быстрый Lighthouse/контраст/токены/OG на десктопе → frontend-perfection
  • Один конкретный баг в меню → см. references/debug-menu-nav.md, но воркфлоу всё равно прогоняйте по уровням.

Необходимые мобильные правила (база)

Все числа — в references/tokens.md. Кратко:

  1. Tap-target ≥ 44×44px для любой интерактивной цели (кнопка, ссылка-иконка, пункт меню). Меньше — не прощается.
  2. Нет горизонтального скролла (overflow-x на <html>/<body> недопустим как постоянное состояние; ловите элемент-нарушитель через scrollWidth > clientWidth).
  3. Якоря под фиксированной шапкой: :target и scroll-margin-top равны высоте sticky-хедера + отступ (обычно scroll-margin-top: calc(var(--header-h) + 16px)).
  4. Safe-area: viewport-fit=cover + env(safe-area-inset-*) для нижней панели (home indicator) и чёлки. Меню/CTA не должны упираться в индикатор.
  5. Шрифты: font-display: swap, мобильная тип-шкала на clamp(), базовый размер ≥ 16px для body (чтобы не зумíло при фокусе поля в iOS).
  6. Токены, а не магия: все цвета/отступы/радиусы — через CSS-переменные, вне токенов — только transparent/currentColor.
  7. Контраст WCAG AA: 4.5:1 текст, 3:1 крупный/UI. Проверяется люменесцентно, не «на глаз».
  8. prefers-reduced-motion: анимации меню/переходов защищены @media (prefers-reduced-motion: reduce).

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.

workflow

Use when a task is too large for turn-by-turn orchestration and should run through the big-task workflow lane: system-wide changes, large migrations, repo-wide audits, high-confidence verification, or tasks explicitly asking to run a workflow.
