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.
