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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00064 | $0.00747 |
| Opus 5 | $0.00032 | $0.00374 |
| Sonnet 5 | $0.00013 | $0.00149 |
| Haiku 4.5 | $0.00006 | $0.00075 |
Grade A, and why
plain-portuguese-explainer 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.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plain-Portuguese Explainer
When to run this skill
- After producing a technical artifact (TECHNICAL-PLAN, sprint plan, architecture decision).
- When the user says "não entendi" / "explica de novo" / "o que isso quer dizer" / "tô perdido".
- After an error message, build failure, or stack trace.
- When introducing a new concept (database, deploy, branch, environment variable, API).
Rules
- Use everyday Portuguese. No English jargon unless impossible to translate, and even then explain it once.
- Use analogies from outside tech. Restaurant, mailbox, car, building.
- Three-line max for the core idea. Then optional "se quiser detalhes" expansion.
- No condescension. The user is smart, just not a dev.
- End with one concrete action the user should take, or "nada que precise fazer agora".
Translation patterns
| Termo técnico | Tradução curta |
|---|---|
| API | "Garçom" — leva pedido pro sistema lá atrás e volta com a resposta. |
| Banco de dados | "Caderno organizado" — guarda informação em linhas e colunas. |
| Branch | "Cópia de rascunho" — pra mexer sem bagunçar a versão principal. |
| Build | "Cozinhar a comida" — pegar os ingredientes (código) e montar o prato final (app). |
| Cache | "Geladeira" — guarda coisas prontas pra não precisar fazer de novo. |
| Deploy | "Colocar a placa de aberto" — sai do seu computador, vira algo que o mundo acessa. |
| Env var | "Bilhetinho secreto" — informação que o app precisa mas não fica no código. |
| Hooks | "Alarme do despertador" — coisa que dispara automático em certos momentos. |
| Linter | "Revisor ortográfico do código". |
| Migration | "Reforma planejada do banco" — muda a estrutura sem perder o que tinha. |
| PR / pull request | "Pedido formal pra entrar mudança" — alguém olha antes de aceitar. |
| Repo / repositório | "Pasta organizada com histórico" de tudo que mudou. |
| Stack | "Conjunto de ferramentas" que o projeto usa. |
| Token | "Chave de cofre" — prova quem você é pra um sistema. |
| Webhook | "Bilhete que cai automático na sua caixa" quando algo acontece num outro sistema. |
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.

plain-portuguese-explainer is a skill published in the GitHub repository lglucas/ai-dev-operating-system (11 stars, last pushed 1mo ago), licensed MIT. It adds 64 tokens to every session and 747 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
