How to use the Brazilian Criminal Law Research agent skill

What the skill makes the agent do

Once installed, the agent answers questions about Brazilian criminal law in Portuguese, focused on the topics listed above. It is meant to explain general concepts, such as what a protective order is or what a police inquiry involves, and to help organise facts for research.

The skill tells the agent to present itself as an informational research assistant without professional legal credentials. Before working, the agent is told to read a longer reference guide (references/detailed-guide.md) that holds the complete procedure and reference material.

The name says 'lawyer', but the skill itself states that it is not a licensed lawyer (advogado), does not represent parties and does not give professional opinions.

Install the advogado-criminal skill

Download the ZIP from our page and unzip it. You can install it in one of two places: your personal skills folder at ~/.claude/skills/, or a project's .claude/skills/ folder if you want it available only for that project.

If you use the Claude apps instead, you can upload the skill under Settings → Capabilities → Skills.

• Personal: unzip into ~/.claude/skills/
• Project only: unzip into the project's .claude/skills/ folder
• Claude apps: Settings → Capabilities → Skills, then upload

Trigger the skill with natural requests

You do not need a special command. The skill is meant to activate when your request mentions topics such as Maria da Penha, violência doméstica, feminicídio, direito penal, crime or criminal. Ask in plain language, in Portuguese or English.

Be specific about what you want to understand. A clear question about a general concept will get a more useful answer than a request to judge a case.

• Explique o que é uma medida protetiva prevista na Lei Maria da Penha.
• O que é um inquérito policial e quem o conduz?
• Qual a diferença entre ação penal pública e ação penal privada?
• Quais são as etapas gerais de uma ação penal no Brasil?

Know what it needs and how it runs

The skill lists no required tools or packages. It does not run scripts and does not use the network, so it works by giving the agent instructions and reference text.

The reference guide notes that it does not record personal or case data by default, and that some legislative tables from an imported reference were removed because they were out of date or wrong. Check dates, the applicable law and current case law yourself before relying on any answer.

• Requires: nothing listed
• Runs scripts: no
• Uses network: no

Safety notes: when not to rely on it

Do not use this skill for advice on your own case. It has no professional credentials, and its output is not a substitute for a licensed lawyer (advogado) or the Defensoria Pública. Wrong guidance could affect your safety or your liberty.

If you or someone else is in immediate danger, do not use this skill. It does not provide emergency contacts or a safety plan. Call the police on 190 or the Ligue 180 service instead.

The content is specific to Brazilian legislation and is not useful for other countries' law.

• Not for personal case advice
• Not for urgent danger: call 190 or Ligue 180
• Not for non-Brazilian law

Tips for better results

Ask one concept at a time, and say whether you are studying or preparing to speak with a lawyer. The skill is built for explanation and organisation of facts, so ask it to summarise terms and structure your questions.

Verify anything important against the primary sources the reference guide links to, such as the Código Penal and the Código de Processo Penal, and against current case law.

• Start with a defined term, then ask a follow-up
• Ask it to list questions to take to a lawyer or the Defensoria Pública
• Check legal points against primary sources before acting on them
