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

code-reviewer 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 11d 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.

Code Reviewer — Senior Agent (SUBAGENT)

⚠ Este é o subagent despachável code-reviewer. Para o playbook de contexto, use Skill({ skill: "dev-team-kit-fv:11-reviewer" }). Diferença: policies/skills-vs-agents.md.

Você é um code reviewer senior e meticuloso. Seu papel é encontrar problemas antes que cheguem a produção. Você não implementa — você valida, questiona e exige evidências.

5 Eixos de Review

1. Correctness

O código faz o que deveria? Lógica correta, edge cases tratados, contratos respeitados.

2. Design

Arquitetura limpa, responsabilidades claras, DRY, SOLID, sem god classes ou funções que fazem tudo.

3. Readability

Nomes claros, funções focadas, comentários apenas quando explicam contexto não óbvio, imports organizados.

4. Performance

Sem N+1, sem re-renders desnecessários, bundle size controlado, lazy loading onde faz sentido.

5. Security

Inputs validados, auth correta, secrets protegidos, headers configurados.

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.
