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

pwa-audit 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.

PWA Audit

Scanner que detecta violacoes de usabilidade mobile-first em componentes React/TSX.

Diferenca do mobile-pwa-usability

Skill Proposito
mobile-pwa-usability Guia — checklist para aplicar ao construir componentes

Quando Usar

  • Apos criar/modificar multiplos componentes interativos
  • Auditoria periodica de compliance PWA
  • Sprint de revisao mobile-first (como o sprint PWA Review)
  • Antes de release que afeta componentes de UI

Criterios de Auditoria

Criterio Regra Padrao Correto Violacao
Touch targets min 44x44px min-h-[var(--touch-target-min)] h-6, h-8, p-1, p-1.5 em botoes
Font size inputs min 16px text-base text-sm, text-xs em <input>, <textarea>, <select>
Touch manipulation Eliminar tap delay touch-manipulation Ausencia em elementos clicaveis
Search inputs Semantica mobile type="search" + inputMode="search" type="text" em campos de busca
Safe areas Suporte notch env(safe-area-inset-*) Elementos fixos sem safe area

Procedimento de Scan

Fase 1: Definir Escopo

Determinar quais arquivos auditar:

# Escopo completo (todos os componentes interativos)
find src -name "*.tsx" | grep -v __tests__ | grep -v '.test.' | grep -v '.stories.'

# Por layer
find src/primitives -name "*.tsx" | grep -v __tests__
find src/layouts -name "*.tsx" | grep -v __tests__
find src/interactions -name "*.tsx" | grep -v __tests__
find src/composites -name "*.tsx" | grep -v __tests__

Fase 2: Scan Automatizado

Buscar padroes de violacao com grep/ripgrep:

Touch Targets Insuficientes
# Botoes com padding pequeno (provavelmente < 44px)
rg '(className.*button|<button|<Button)' --type tsx -l | \
  xargs rg 'p-1[^0-9]|p-1\.5|h-6 |h-7 |h-8 |w-6 |w-7 |w-8 ' --type tsx -n

# Botoes SEM touch target minimo
rg '<button' --type tsx -l | \
  xargs rg -L 'touch-target-min|min-h-\[44|min-h-\[2\.75' --type tsx

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.
