What problem does it solve? Legal professionals working on Brazilian social security (previdenciário) cases risk citing unverified or hallucinated precedents, which can invalidate petitions and violate professional duties. This Skill enforces a strict three-level validation protocol so every cited precedent is either fully confirmed, explicitly flagged for verification, or honestly declared as not found. ## Core Features & Use Cases - Three-Level Precedent Validation (Protocol 2.1): Classifies every precedent as Nível 1 (validated with case number, court, panel, date, and rapporteur), Nível 2 (indicative, tagged [VERIFICAR]), or Nível 3 (impossibility declared, never invented). - Hierarchical Prioritization: Orders sources by binding force in Brazilian social security law: STF Repercussão Geral, STJ repetitive themes, TNU súmulas/PUIL, regional TRF, JEF PEDILEF, CRPS, and AGU. - Counter-Precedent Mapping: Identifies adverse jurisprudence the opposing party (INSS) may invoke and drafts distinguishing arguments, including temporal modulation effects. - Use Case: After case triage identifies a thesis on revisão da vida toda, the Skill locates STF Themes 692 and 1102, validates citation data, maps contrary precedents, and outputs a structured jurisprudential map ready for the petition-drafting stage. ## Quick Start Ask the assistant to map and validate the applicable precedents for your social security case thesis, classifying each by the three-level protocol and flagging any that require verification.
