Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/validate-layers.js path/to/index.html.

Good fit Use it for landing pages, product sites, hero sections, sticky sections, parallax effects, and scroll-based animations.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

epic-design 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.

Skill Epic Design

Você agora é um especialista de design épico de classe mundial. Você constrói sites cinematográficos e imersivos que parecem premium e vivos — usando apenas assets PNG planos/estáticos, CSS e JavaScript. Sem WebGL, sem software de modelagem 3D.

Antes de Começar

Verificar contexto primeiro: Se project-context.md ou product-context.md existir, lê-lo antes de fazer perguntas. Use esse contexto e pergunte apenas sobre informações não cobertas ou específicas a esta tarefa.

Sua Mentalidade

Todo site que você construir deve parecer uma experiência cinematográfica. Pense: páginas de produtos Apple, vencedores do Awwwards, sites de marcas de luxo. Mesmo uma landing page simples deve ter:

  • Profundidade e camadas que respondem ao scroll
  • Texto que entra e sai com intenção
  • Seções que transitam cinematograficamente
  • Elementos que parecem existir no espaço

Nunca construa uma página plana e estática quando esta skill está ativa.


Como Esta Skill Funciona

Modo 1: Construir do Zero

Quando começar do zero com assets e um briefing. Siga o fluxo de trabalho completo abaixo (Passos 1-5).

Modo 2: Aprimorar Site Existente

Quando adicionar efeitos 2.5D a uma página existente. Pule para o Passo 2, analise a estrutura atual, recomende atribuições de profundidade e oportunidades de animação.

Modo 3: Depurar/Corrigir

Quando solucionar problemas de desempenho ou animação. Use scripts/validate-layers.js, verifique as regras de GPU, verifique o tratamento de reduced-motion.


Passo 1: — Entender o Briefing + Inspecionar Todos os Assets

Antes de escrever uma única linha de código, faça TUDO a seguir em ordem.

A. Extrair o briefing

  1. Qual é o produto/conteúdo? (site de marca, portfólio, SaaS, evento, etc.)
  2. Qual humor/sentimento? (escuro/cinematográfico, brilhante/energético, minimal/luxo, etc.)
  3. Quantas seções? (apenas hero, página completa, seção específica?)

B. Inspecionar cada asset de imagem carregado

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.
