Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00154 | $0.01330 |
| Opus 5 | $0.00077 | $0.00665 |
| Sonnet 5 | $0.00031 | $0.00266 |
| Haiku 4.5 | $0.00015 | $0.00133 |
Grade A, and why
brain 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brain — segundo cérebro em LLM Wiki (OKF v0.2)
Papel
Roteador e guardião do formato: leva cada intenção do usuário para a operação certa e impede escrita fora do fluxo.
Princípio central
Nada entra na wiki sem discussão e sem citação. A wiki acumula valor porque cada afirmação tem fonte e cada mudança passa pelo usuário — gravar direto "para agilizar" destrói exatamente o que a torna confiável.
Antes de começar
- Leia
.claude/pwdev-brain-context.md— idioma, caminho do brain, identidade e preferências. - Sem contexto ou sem
<brain>/wiki/index.mdválido → pare e aponte/pwdev-brain:init. - Idioma conforme
${CLAUDE_PLUGIN_ROOT}/references/language.md; formato conforme${CLAUDE_PLUGIN_ROOT}/references/okf-spec.md.
Framework — intenção → operação
| Intenção do usuário | Operação |
|---|---|
| "adiciona/salva/ingere isso" (arquivo, link, artigo, paper) | /pwdev-brain:ingest <fonte> |
| "o que minha wiki/brain diz/sabe sobre X", perguntas sobre o acervo | /pwdev-brain:query <pergunta> |
| "gera um relatório/comparativo a partir do meu brain" | /pwdev-brain:query (artefato em wiki/output/) |
| "valida/limpa/organiza a wiki", "tem link quebrado?" | /pwdev-brain:lint |
| "cria/configura meu segundo cérebro" | /pwdev-brain:init |
| "como está meu brain?" | /pwdev-brain:status |
Mapa de intenção → tool MCP (leitura rápida)
Path A — MCP brain conectado: para leituras pontuais em conversa
natural, use as tools direto — mais barato em contexto que abrir arquivos:
| Intenção | Tool |
|---|---|
| Panorama/diagnóstico do brain | brain_info (caminho, resolved_via, contagens) |
| Ponto de entrada da wiki | brain_index |
Listar conceitos (filtro por type/status/tag) |
brain_list |
| Buscar por termo (ranqueado, com snippets) | brain_search |
Ler conceito ou fonte (wiki/…, raw/…) |
brain_get |
| Histórico de mudanças | brain_log |
Path B — MCP ausente ou falhando: não simule resultado de tool. Siga o
fluxo filesystem dos comandos (index → conceitos → Grep dirigido). Falha
com brain válido é quase sempre sessão iniciada antes do plugin/env var
ou node ausente — aponte /pwdev-brain:status e reinício de sessão.
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.

brain is a skill published in the GitHub repository pwdev-solucoes/pwdev-claude-marketplace (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 154 tokens to every session and 1,330 once invoked, about $0.0008 per session on Opus 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.
