Use Cases

Real-world ways to use lex-intelligentia-skills

Draft a preliminary sentença with proper structure

👤 Magistrados and law clerks preparing draft decisions ⏱ ~30 min advanced

When to use: You have the case file and need a first pass at the relatório / fundamentação / dispositivo structure.

Prerequisites

Case facts summarized in a document — Export from your court system or paste into the chat
Skill installed — git clone https://github.com/fbmoulin/lex-intelligentia-skills ~/.claude/skills/lex-intelligentia-skills

Flow

Feed the case file

Use lex-intelligentia-skills. Aqui está o caso [...]. Prepare um esboço de sentença com relatório, fundamentação e dispositivo.✓ Copied

→ Três seções claramente divididas, citações a CPC e CF
Ask for jurisprudence support

Sugira precedentes do STJ e STF aplicáveis aos pontos controvertidos.✓ Copied

→ List of case citations with súmulas numbers
Human review pass

Liste pontos onde o magistrado deve revisar pessoalmente antes de assinar.✓ Copied

→ Checklist of required human judgment moments

Outcome: A formatted draft sentença ready for the judge's own review and refinement — never signed as-is.

Pitfalls

LLM hallucinates jurisprudence citations — Always verify every case number and súmula against an official source (STJ, STF sites) before using

Combine with: filesystem

Compose a petição inicial with cause of action and pedidos

👤 Advogados starting a new civil action ⏱ ~45 min intermediate

When to use: You have the facts and legal theory; you need a well-structured petition.

Flow

Describe the case and desired relief

Com lex-intelligentia-skills, redija uma petição inicial para ação de cobrança com pedido de tutela de urgência. Fatos: [...]✓ Copied

→ Standard sections: qualificação, fatos, direito, pedidos, valor da causa
Refine pedidos

Revise os pedidos para que sejam certos, determinados e consequenciais.✓ Copied

→ Numbered, precise pedidos with procedural basis

Outcome: A petition draft structured to Brazilian civil procedure rules.

Pitfalls

Generic templates that ignore local court practice — Adjust for your specific tribunal's peculiarities; review with a senior colleague

Produce a legal research memo on a doctrinal question

👤 Pesquisadores jurídicos, law clerks ⏱ ~30 min intermediate

When to use: You need a structured memo on how Brazilian law treats a specific question.

Flow

Frame the question

Use lex-intelligentia-skills. Memorando sobre: responsabilidade civil do Estado em casos de omissão administrativa. Abordagem atual do STF?✓ Copied

→ Structured memo with doutrina, jurisprudência, conclusão
Ask for dissent and controversy

Quais divergências doutrinárias ou mudanças recentes de posicionamento?✓ Copied

→ Explicit acknowledgment of tensions, not a flattened summary

Outcome: A research memo a senior lawyer can actually use as a starting point.

Pitfalls

Citations invented by the model — Cross-check every citation. LLMs are especially bad with numeric case references.

Combine with: paper-fetch-skill

Combinations

Tools

What this MCP exposes

Tool	Inputs	When to call
sentenca_draft	case facts	Preparing judicial decisions
peticao_generator	facts, cause of action	Drafting civil petitions
jurisprudencia_search	legal topic, court	Finding relevant case law — always verify
memo_juridico	research question	Writing doctrinal analysis

Cost & Limits

What this costs to run

API quota: None
Tokens per call: Variable — legal texts tend to be long
Monetary: Free
Tip: For long sentenças, work in sections to avoid context overflow.

Security

Permissions, secrets, blast radius

Credential storage: No credentials

Data egress: None — local skill prompts only; be aware case data sent to Claude API

Case data may include sensitive personal information under LGPD — anonymize before sharing with the model if required by internal policy.
Outputs are drafts, never final. A magistrado or advogado must review and take responsibility.

Troubleshooting

Common errors and fixes

Cited case numbers don't exist

LLMs hallucinate legal citations. Verify every reference against the official court website before use.

Verify: Manual check on stj.jus.br or stf.jus.br

Formatting doesn't match my tribunal

Provide an example document from your tribunal; Claude will match its structure.

Output is in English

Prompt explicitly in Portuguese; reference the skill by name in Portuguese.

Alternatives

lex-intelligentia-skills vs others

Alternative	When to use it instead	Tradeoff
Generic Claude without skill	Non-Brazilian legal work	No Brazilian-specific formatting, higher hallucination rate
Commercial legal AI (Jusbrasil AI, Jurimetria)	You need sourced, up-to-date jurisprudence databases	Paid; this skill is for drafting, not authoritative research
