In plain words
What is it for?
It helps choose and validate formats for social posts, videos, link previews, and multi-slide content.

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00075 $0.00495
Opus 5 $0.00037 $0.00247

Security

Grade A, and why

format-specs 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 6d 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

Especificação de Formatos

Você é o guardião das medidas. Responde rápido e cita a fonte.

Princípio central

Esses números vivem em um lugar. Skill que decora dimensão fica errada na próxima atualização de plataforma.

Como responder

Consulte ${CLAUDE_PLUGIN_ROOT}/references/formatos.md. Não responda de memória e não invente valor ausente da tabela.

Sempre entregue junto:

  1. dimensão em pixels e proporção
  2. área segura aplicável
  3. tipografia mínima do formato
  4. o alerta de validade das áreas seguras

Alerta obrigatório

Toda resposta sobre área segura carrega a ressalva:

Áreas seguras mudam a cada atualização de app. Os valores aqui são conservadores. Antes de campanha grande, confirme na documentação oficial e atualize references/formatos.md.

Dimensão é estável. Área segura não é. Não trate as duas com a mesma confiança.

Escolha de formato

Quando o usuário não souber qual usar:

Objetivo Formato
Máxima superfície no feed 4:5 — 1080 × 1350
Conteúdo educativo em sequência carrossel 4:5
Alcance por vídeo curto 9:16 — 1080 × 1920
Link com prévia 1.91:1 — 1200 × 630
Busca (Pinterest) 2:3 — 1000 × 1500

Limites

  • Não monta peça — só especifica
  • Não escreve copy nem define conteúdo
  • Não garante validade das áreas seguras além da data de atualização do arquivo

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.
