Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 27 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 497 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00027	$0.00497
Opus 5.5	$0.00011	$0.00199
Sonnet 5.5	$0.00005	$0.00099
Haiku 4.5	$0.00003	$0.00050

Measured today against content hash 2b3d235ab629, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

prodx-existe 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 today.

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

Use a skill prodx, etapa P3, seguindo references/03-existencia.md.

O que procurar está em $ARGUMENTS. Se vier vazio, pergunte o que se quer verificar e pare.

Modo consulta

Rodando isolada, esta etapa responde no chat e não cria arquivo. Só grava 02-existencia.md quando estiver dentro de uma avaliação completa com pasta já criada.

Roteiro

Procure o problema resolvido, não o artefato pedido. Nesta ordem:

Mapa de funcionalidades do PRODUTO.md
Índice do memox, por termo e por módulo
Telas, rotas e relatórios do sistema — busque em português e em inglês
Relatórios de uso do runx — descrevem o sistema na linguagem do cliente
Pedidos já avaliados no INDICE.md — ja_existe e nao_fazer com termos próximos

Saída

Existencia — "<o que foi procurado>"
Termos: <termos e sinonimos>
Desfecho: <EXISTE | EXISTE PARCIAL | NAO EXISTE>
Evidencia: <tela + caminho | rota + arquivo:linha | ocorrencia + trecho>
Se PARCIAL, falta: <o que falta, e o tamanho relativo ao pedido>
Onde procurei sem achar: <lugares>

Regras

Regra 5: "acho que já tem" não é resposta. Toda afirmação vem com evidência.
Registre também onde procurou e não achou — é o que impede a próxima pessoa de repetir a busca.
Antes de declarar EXISTE, confirme que o perfil de quem pediu tem acesso. Se não tem, é EXISTE PARCIAL.
Funcionalidade que existe mas está quebrada não é existência: é correcao.
Dado que existe em tabela sem tela que o exponha é NÃO EXISTE para o usuário.
Sem memox ou sem relatórios do runx: registre a ausência, marque a confiança como reduzida, e siga. Nunca bloqueia.

Changes

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.
