What problem does it solve? Brazilian social security (previdenciário) cases depend on the CNIS extract, but reading it manually is error-prone: overlapping employment periods, administrative pendency indicators (PE, PVI, IREC), and missing contribution months can silently invalidate time and carência calculations. This Skill structures the CNIS analysis so no vínculo, pendency, or omission is missed before drafting any petition or calculation. ## Core Features & Use Cases - CNIS Data Extraction: Structures insured identification, NIT, and every employment/contribution vínculo with employer, category, dates, and contribution salaries. - Pendency Detection: Identifies administrative indicators (PE, PVI, IREC, IEAN, IPESC, IGFIP) and proposes a remediation strategy for each. - Time & Carência Mapping: Builds a vínculo table, resolves concomitant periods, converts special time (1.4x/1.2x), and counts carência month by month under Lei 8.213/91. - Use Case: A lawyer receives a client's CNIS PDF before filing a retirement claim. The Skill produces a report with total contribution time, carência count, flagged pendencies, and rural/special period opportunities, satisfying the mandatory pre-analysis protocol (PA-13). ## Quick Start Attach the client's CNIS extract and ask the assistant to analyze the CNIS, mapping all vínculos, contribution time, carência, and pendencies before drafting any benefit petition.
