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 | $0.06410 | $0.06410 |
| Opus 5.5 | $0.02564 | $0.02564 |
| Sonnet 5.5 | $0.01282 | $0.01282 |
| Haiku 4.5 | $0.00641 | $0.00641 |
Grade A, and why
code-ai-template AGENTS.md 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 5d 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Instruções para o agente de código deste projeto. Núcleo agnóstico de ferramenta e fonte única de toda regra de método — vale em qualquer stack e qualquer agente. Use como está. Regra agnóstica nova entra aqui, nunca só num flavor; flavor duplica significado só em material on-invocation (runbook de skill), com nota de sync.
- Flavors (só mecânica da própria ferramenta + ponteiros): Claude Code →
CLAUDE.md· Cursor →.cursor/rules/metodo.mdc. - Convenções de código/UI deste projeto:
CONVENCOES.md. Linguagem ubíqua do domínio:CONTEXT.md. - Projeto de LLM/agentes: acople o add-on opcional e referencie aqui (ex.:
PERFIL-LLM.md). Instruções no README.
O loop — plan e code
Uma superfície, dois modos — os dois são você, os dois com o repo na mão:
- Plan mode (raciocínio): lê os docs vivos e audita o código real, discute o aberto com o dono (uma pergunta por vez), e grava a spec da fase no
docs/SETUP.md— e para aí. Ler código é o trabalho desta passada; escrever código é da outra. - Code mode (execução): em sessão nova (contexto limpo), lê a spec do
SETUP.md, implementa aterrado no código, roda os critérios de sucesso na mesma resposta, e atualiza os docs vivos numa única passada antes de encerrar.
Entre os dois, uma fronteira dura: é o dono que limpa o contexto e abre a execução. Cada fase é tarefa independente — o contexto mora nos docs vivos, não na sessão.
Como o planejador tem o repo, a spec nasce confirmada contra o código: nomes de arquivo e símbolo são verificados no plan mode, não "hipóteses a confirmar". Ainda assim a verdade é o código — se em code mode a realidade diverge da spec, implemente o que é correto e registre a divergência (nota na fase, ou ADR se for decisão de arquitetura).
Regra que precisa valer sempre vira hook. Este arquivo e as skills aconselham — quem lê é o agente, e agente esquece; só o hook enforça, porque roda fora do modelo e barra a chamada antes de ela acontecer. Skill é ordem de passos, não guardrail. Daí o critério: regra violada mais de uma vez é candidata a hook, e a regra escrita continua sendo o porquê que a mensagem do bloqueio cita — hook sem regra escrita vira parede sem explicação. Os dois hooks do template mostram a forma: .claude/hooks/block-dangerous-git.sh (git destrutivo) e .claude/hooks/block-comandos-do-dono.sh (o git add cego, mais exemplos comentados dos comandos que só o dono roda). O inverso também vale: hook que não paga um risco medido não entra — meça antes de escrever guardrail contra um problema que você supõe ter.
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.

code-ai-template AGENTS.md is an instructions file published in the GitHub repository FHDumont/code-ai-template (2 stars, last pushed 5d ago), licensed MIT. It adds 6,410 tokens to every session, about $0.0256 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
