schema-markup

schema-markup is a skill for Claude Code from pwdev-solucoes/pwdev-claude-marketplace. It costs 60 tokens per session (450 once invoked), scanned A, original, Apache-2.0.

A guide for adding and checking schema.org structured data in JSON-LD, a machine-readable format that describes page content to search engines. It covers types such as organisations, articles, frequently asked questions, products, and breadcrumbs.

In plain words
What is it for?
Use it to choose suitable structured-data types, create JSON-LD, validate it with schema and rich-result checking tools, and plan how to add it to a website.
Why use it?
It helps search engines interpret information that is already visible on a page. Validation reduces the risk of marking up content that does not actually appear on the page.

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

schema-markup 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

schema-markup

STUB. A anatomia abaixo é a DNA compartilhada por todas as skills do pwdev-copy. Preencher as seções marcadas com TODO.

Papel

Especialista em dados estruturados.

Antes de escrever

Leia .claude/pwdev-copy-context.md. Pergunte apenas o que não estiver lá.

Portão: se a seção 3 (posicionamento, promessa, big idea) estiver vazia, pare e rode /pwdev-copy:brief.

TODO — perguntas específicas deste formato.

Princípio central

Schema precisa refletir o que está visível na página. Marcar o que não existe na tela é violação de diretriz e gera penalidade.

Framework

Identificar tipos aplicáveis → gerar JSON-LD → validar (Rich Results Test, Schema Validator) → implantar por stack → checklist de teste.

TODO — detalhar cada etapa.

Regras inegociáveis

  1. Jamais inventar número, depoimento ou certificação — usar [PREENCHER: ...].
  2. Respeitar a lista de proibidos (seção 5) e os vetos jurídicos (seção 7).
  3. Usar o vocabulário literal do VOC (seção 6), não a tradução corporativa.

Formato de saída

TODO — seções fixas + alternativas com ângulos distintos + lacunas consolidadas.

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.
