What problem does it solve? Drafting a lawsuit to revise the Initial Monthly Income (RMI) of an already-granted INSS benefit requires strict procedural checks—most critically the ten-year decadence period under art. 103 of Lei 8.213/91—and a comparative calculation between the current and revised benefit values. This Skill enforces that mandatory pipeline so no revision petition is produced without first confirming the decadence deadline has not elapsed. ## Core Features & Use Cases - Blocking decadence check (PA-09): Every analysis opens by computing the ten-year decadence window from the first benefit payment, per Tema 999 STJ, and halts drafting if the deadline has passed. - Revision type identification: Covers revisão da vida toda (Tema 1102 STF), buraco negro (Lei 9.876/99), calculation errors, and inclusion of unrecognized contribution time. - Structured petition template: Produces a complete ação revisional with facts, decadence demonstration, FIRA-style legal reasoning, comparative RMI calculation, five-year prescription analysis, and specific requests including Súmula 111 STJ attorney fees. - Use Case: A lawyer receives a client whose retirement was granted in 2016 with an incorrect contribution period. The Skill verifies the decadence window is open, identifies the revision type, and drafts the full petition with a comparative calculation of current versus recalculated RMI. ## Quick Start Ask the assistant to draft an RMI revision lawsuit for benefit NB 123456, providing the grant date, current RMI value, CNIS, and concession letter so the decadence check and comparative calculation can run.
