criar-prd

criar-prd is a skill for Claude Code from hmaurus/skills. It costs 49 tokens per session (970 once invoked), scanned A, original, MIT.

A product-requirements interview workflow that asks about the problem, users, scope, and success, then writes or revises a PRD. A PRD is a document describing what a product is for and what it will include.

In plain words
What is it for?
Use it at the start of a product project or when a new decision conflicts with the existing requirements.
Why use it?
It turns an unclear product idea into shared requirements and exposes decisions that would otherwise be hidden in implementation work.

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

criar-prd 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Criar o PRD por entrevista

O PRD responde o que nenhuma linha de código responde: para quem o produto existe, o que ele não vai fazer, e o que conta como sucesso. É o documento do qual sai o primeiro checklist.

Rodar fora do plan mode: o passo final grava arquivo.

Não confundir com /aicf:criar-spec — a spec descreve uma mudança e tem um estado "pronto"; o PRD descreve o produto e é revisado toda vez que uma decisão o contraria, por isso esta skill roda de novo, sem cerimônia de fechamento.

Onde ele fica

docs/projeto/PRD.md. Se já existe preenchido, é modo revisão: ler antes de perguntar, mostrar o que já está respondido e entrevistar só o que mudou ou ficou aberto — não reescrever seção que continua válida. Sem docs/projeto/, perguntar onde gravar em vez de inventar pasta.

Como entrevistar

Começar pelo problema, não pela solução. Quem chega já sabendo o que quer construir começa descrevendo a tela; puxar de volta uma vez — "e o que está errado hoje, para alguém que ainda não tem isso?" — e seguir. Produto desenhado a partir da solução resolve o problema de ninguém.

Ordem que funciona: problema → quem sofre com ele → o que passa a existir → escopo → modelo → sucesso → riscos.

Uma pergunta de cada vez: AskUserQuestion para escolha (o que fica fora, qual modelo, qual sinal de sucesso), aberta para o descritivo (problema, público, proposta) — menu ancora quem ainda não formou opinião sobre o próprio produto.

As três armadilhas

"Fora de escopo" respondido com vazio. É a seção que mais se paga — a que impede a mesma discussão de voltar em seis meses — e a que todo mundo pula. Diante de "nada por enquanto", listar o que apareceu na conversa e não entrou, e perguntar de cada item: foi decisão ou esquecimento? Decisão vai para a seção com o motivo; esquecimento volta para o escopo.

Preencher o que ele não sabe. Público sem resposta é "a definir", não um perfil plausível inventado pelo agente. Documento com resposta inventada é pior que documento com lacuna: a lacuna alguém preenche, a invenção alguém segue.

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.
