imagem

imagem is a skill for Claude Code from inhabitants/sapiens-mcp. It costs 47 tokens per session (2,649 once invoked), scanned A, original, MIT.

A guide for writing prompts for the service's image generator, including layout rules, model selection, aspect ratios, and reference images. It focuses on making the main subject large and prominent in the frame.

In plain words
What is it for?
Use it before generating images to choose a suitable model and write prompts for portraits, anime, readable text, character consistency, or other supported image goals.
Why use it?
It reduces generic compositions and common prompt choices that lead to small subjects, borders, or unwanted styles. It also explains how to filter available models by the kind of image they are suited to produce.

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

imagem 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Imagem na régua da casa

A regra do prompt

Full-bleed. Sujeito oversized, ocupando 70% ou mais do frame. Sem moldura, sem margem, sem cena pequena em paisagem vasta.

Proibidos no prompt: "tarot card illustration", "intimate scale", "card-style portrait", "watercolor portrait of", "small subject in vast landscape". São os padrões que sabotam o resultado e entregam imagem genérica.

O básico

action=generate com prompt, model e aspectRatio. action=models (sem custo, sem login) lista o catálogo vivo com preço atual, resolução máxima e se o modelo aceita referência.

O preço de models é o do 1K. Sem size, nano-banana-2, nano-banana-max e a família Krea 2 geram em 2K e somam o adder de 2K: passe size: "1K" quando o barato importar mais. O que foi debitado de verdade volta em custoSinapses no retorno do generate; cite esse, não o da lista.

Escolher motor em dois passos

A lista de action=models é longa e segue a ordem da prateleira da casa, não o preço, e nenhuma das duas é a pergunta de quem vai gerar. Três campos do payload resolvem isso:

  • bestFor: pra que o motor serve, num vocabulário fechado (foto, anime, texto pra palavra legível na arte, personagem pra segurar a mesma pessoa, adulto). FILTRE por aqui antes de comparar preço.
  • family + variant: motores com a MESMA family são o mesmo motor em versão diferente (Flux.2 Klein tem Base, Anime, Celular e Transparência; Krea 2 tem Realism e Transparência; Gemini tem 3 Pro e Nano Banana 2.1; GPT Image tem 2 Low, 2 High, 2.5 Flare e 2.5 Sunburst). O retorno traz um índice families já montado.
  • ousadia: nudez é NÍVEL, não motor. Quando o campo vem preenchido, a mesma escolha tem uma versão com nudez: gere com ousadia.model + loraIntensity (suave, medio, forte) pra ter nudez, e com o id da linha pra não ter. Não procure um motor "+18" ou "Nu" separado na lista: ele virou este campo.

Texto legível na arte (placa, rótulo, pôster com acento): a família GPT Image é a de referência. Dentro dela, o 2.5 acerta letra pequena e acento cobrando menos que o 2 High; o Flare é o rápido, o Sunburst segura composição densa e edição em várias voltas. O preço vivo de cada um sai em action=models.

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.
