SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Legal research on Brazilian case law often relies on memory or unverified sources, leading to fabricated citations. This Skill connects the assistant to the IAJUS MCP server so every precedent, súmula, or theme cited comes from a real query against official sources with stable links. ## Core Features & Use Cases - Seven search modalities: semantic, hybrid (RRF fusion), full-text, regex, CNJ case-number lookup, OJBU ontology browsing, and citation-graph traversal, plus qualified-precedent search (súmulas, repercussão geral, repetitivos, IRDR) and STF/STJ informativos. - Honesty envelope: reads the desfecho field before any counting so empty results, errors, and partial coverage are reported accurately instead of being filled with invented precedents. - Anti-hallucination citation pass: every citation must come from a real tool call in the session, with link_completo, vigência status, and authorship (redator_acordao) verified before delivery. - Use Case: A lawyer asks for the current STJ position on dano moral por inscrição indevida. The Skill first queries qualified precedents, then escalates through hybrid and semantic search, and returns súmulas and acórdãos with official links and vigência confirmed. ## Quick Start Ask the assistant to research the current STJ understanding on a legal topic and cite the official sources for each precedent found.

FAQPage Schema
How do I search Brazilian case law with the IAJUS MCP server?▼

Start with buscar_semantica for conceptual questions or buscar_hibrida for maximum relevance, then escalate to buscar_fts, buscar_regex, buscar_por_ontologia, or buscar_por_cnj depending on the query shape. For consolidated positions, query buscar_qualificada first since qualified precedents outweigh isolated acórdãos.

Which search modality should I use for legal research?▼

Use buscar_semantica for conceptual themes, buscar_hibrida for best overall relevance, buscar_fts for exact technical terms, buscar_regex for literal citation patterns, buscar_por_cnj for case numbers, buscar_por_ontologia for entire legal branches, and buscar_por_citacoes for citation networks.

Does the skill cover legislation as well as jurisprudence?▼

No. This skill is explicitly scoped to jurisprudence and its description states it should not be used for laws. Legislation research with vigência checking is handled by a separate legislacao-juris capability in the same plugin.

What does the desfecho field mean in search results?▼

The desfecho envelope reports query outcome: sem_resultado is a measured zero, erro means the query failed, nao_terminou indicates timeout, parcial means incomplete coverage, and medida_indisponivel means the source carries no measure. Only sem_resultado may be reported as a true absence.

Why does filtering by tribunal fail in some search tools?▼

Only buscar_semantica and buscar_hibrida accept the tribunal parameter; buscar_regex, buscar_fts, and buscar_por_ontologia require orgao_code, the lowercase slug instead. Passing tribunal to those tools is rejected, so resend with the correct parameter.

How are citations verified before delivery?▼

Every citation must originate from a real tool call in the session, carrying the link_completo returned by the source. The skill checks existence, fidelity of ementa and relator, and status_vigencia before delivery, and anything not returned by a tool is reported as not located.
