criar-skill

criar-skill is a skill for Claude Code from georgemarmelstein/superjurista-dev. It costs 84 tokens per session (6,287 once invoked), scanned A, original, MIT.

A guide for creating, changing, or packaging reusable instructions for an AI coding assistant. It describes how to turn a repeated workflow or specialized knowledge into a skill.

In plain words
What is it for?
Creating new skills, improving existing ones, packaging workflows, and testing whether the instructions guide the assistant correctly.
Why use it?
It provides a defined process for building and testing skills instead of assembling them inconsistently. It also clarifies which agents handle each part of the work.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; names the TodoWrite tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the superjurista-dev plugin — 11 skills, 22 commands, 7 agents shipped together

Good fit Creating new skills, improving existing ones, packaging workflows, and testing whether the instructions guide the assistant correctly.

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

criar-skill 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 — 617 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<quando_usar> Use quando: - Usuário pede para "criar skill" ou "nova skill" - Usuário quer "transformar workflow em skill" - Usuário menciona "empacotar conhecimento" - Usuário quer "automatizar" um processo repetitivo do Claude - Usuário pede para "melhorar" ou "refatorar" skill existente

<regras_uso> - Subagentes LEEM agents/ diretamente (não recebem cópia) - Orquestrador NÃO executa tarefas dos subagentes - Cada subagente tem contexto ISOLADO - Apenas orquestrador usa TodoWrite </regras_uso>

**Nota sobre Write:** Esta skill usa Write diretamente na Etapa 4 para
criar os arquivos da skill-alvo. Isso é uma exceção justificada ao padrão
"orquestrador não usa Write": aqui o orquestrador É o criador — não há
subagente de escrita porque a montagem do SKILL.md depende do contexto
acumulado das etapas anteriores.

<teste_green_falha> Se o agente ainda VIOLA na fase GREEN (escolhe A com skill): → Skill não está clara o suficiente → Identificar falha específica na instrução → Adicionar regra ou racionalização → Re-testar (máximo 2 tentativas) </teste_green_falha>

<teste_competing_falha> Se o agente CEDE ao pedido contrário na fase COMPETING: → A skill depende do apoio do prompt (falha silenciosa) → Adicionar à a desculpa "o usuário pediu/autorizou" → Re-testar (máximo 2 tentativas) → Persistindo: registrar a pendência no relatório final (não-bloqueante) </teste_competing_falha>

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
