jev-opportunity-scout

jev-opportunity-scout is a skill for Claude Code from felvieira/claude-skills-fv. It costs 239 tokens per session (3,125 once invoked), scanned A, original, Apache-2.0.

A code-scanning review skill that finds fragile ways of making semantic decisions, such as string checks, regular expressions, hard-coded keywords, or generic language-model parsing. It recommends specific typed judgment replacements and shows where they would fit.

In plain words
What is it for?
Use it to review a project for classification, detection, scoring, routing, or verification logic that could use typed judgments. It helps prepare candidates and reasoning for a later integration design.
Why use it?
It replaces vague suggestions with concrete findings: the file and line involved, why the current approach is fragile, and an example replacement call. It stops at analysis and recommendation rather than performing the integration.

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

jev-opportunity-scout 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 1mo 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.

Jev Opportunity Scout — Onde um Judgment Tipado Resolveria Melhor

Varre o projeto atual, encontra pontos onde uma decisão semântica (classificar, detectar, pontuar, rotear, verificar) está implementada com heurística frágil, e entrega candidatos concretos migrados pro formato real do Jev (modelo System One da TypeSafe) — com localização exata, primitivo certo (Choice/Noul/Score), chamada de exemplo pronta pra copiar, e custo real calculado. Ser assertiva é o ponto desta skill: não é um relatório morno de "talvez isso ajude" — é apontar o arquivo, a linha, o motivo concreto de fragilidade, e a chamada exata que resolveria, pra quem for decidir ter o material completo na mão, não um resumo vago.

O handoff pra integrar de fato é a skill 25 (AI Integration Architect) pra desenho de adapter, ou instalar npx skills add typesafe-ai/skills --skill typesafe-ai direto — mas o trabalho de achar e justificar os candidatos é inteiro desta skill, feito com profundidade, não terceirizado por preguiça.

Governanca Global

Esta skill segue GLOBAL.md, policies/execution.md, policies/handoffs.md, policies/tool-safety.md.

Regra de escopo: análise e recomendação, não a integração final. allowed-tools não inclui Bash/Write/Edit porque o trabalho é ler o codebase e produzir o relatório — não porque a skill deva ser tímida sobre o que encontra. Escrever o adapter, configurar credencial, ou editar o código de produção é trabalho da skill 25 ou de implementação direta, depois que os candidatos concretos desta skill já estiverem na mesa. A skill entrega munição completa, não uma sugestão frouxa.

Regra de honestidade de custo. Todo candidato reportado inclui o custo real por chamada, calculado a partir do preço documentado ($0.042 por milhão de tokens de input, output gratuito — ver references/pricing.md), não uma estimativa vaga. Se o volume do candidato for alto (ex.: rodar em cada request de produção), calcular o custo mensal projetado e destacar isso — o ponto não é vender a integração, é dar dado suficiente pra decisão.

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.
